Unsaturated Polyester Resin (UPR) Recycling and Circular Economy Trends

The unsaturated polyester resin (UPR) market is undergoing significant transformation as industries around the world strive to adopt more sustainable practices. As UPR is widely used in industries like automotive, construction, and marine for its durability and strength, its environmental impact has come under scrutiny. One of the major challenges is the difficulty in recycling UPR, which has traditionally been a barrier to implementing a circular economy in this sector.

However, as sustainability becomes a top priority, efforts to integrate UPR into a circular economy are gaining traction. The idea of a circular economy revolves around minimizing waste, extending the life of products, and reusing materials wherever possible. For UPR, this means rethinking how the material is produced, used, and ultimately disposed of. Let’s explore how the UPR industry is shifting towards more sustainable practices, focusing on recycling innovations and circular economy trends.

The global unsaturated polyester resins market is valued at USD 8.50 billion in 2024 and is projected to reach USD 10.29 billion by 2029, growing at 3.9% cagr from 2024 to 2029.

Recycling Challenges with UPR

One of the fundamental properties of unsaturated polyester resins is their ability to create strong, thermoset materials once cured. These materials are highly valued for their strength, but their inherent structure makes them difficult to recycle. Unlike thermoplastics that can be melted down and reshaped, thermosetting resins like UPR do not revert to a malleable state after curing, making traditional recycling methods ineffective.

In addition to the challenge posed by its chemical structure, UPR is often combined with glass fibers and other additives to create composite materials, further complicating the recycling process. Separating these components at the end of a product’s life is not only difficult but also costly, leading to large amounts of UPR-based materials ending up in landfills.

Circular Economy and UPR: Shifting Towards Sustainability

Despite these challenges, the drive toward a circular economy is leading to significant changes in how UPR is being approached. A circular economy model emphasizes keeping materials in use for as long as possible, recovering and regenerating materials at the end of their life cycle. For UPR, this shift is taking several forms:

Designing for End-of-Life Recovery: One of the key principles of a circular economy is designing products with their entire lifecycle in mind, including what happens after their useful life. In the UPR market, this involves developing resins that are easier to recycle or disassemble once they reach the end of their use. This shift in product design requires collaboration across the supply chain, from manufacturers to recyclers, to ensure that products can be effectively processed for reuse.

Chemical Recycling Innovations: While traditional mechanical recycling methods fall short for UPR, chemical recycling offers a promising alternative. Through chemical recycling, UPR can be broken down into its original components, which can then be reused to produce new resins. This approach, though still in the early stages of development, has the potential to significantly reduce waste. Technologies like pyrolysis and solvolysis are being researched as potential solutions to chemically break down UPR composites. While these processes currently require significant energy input, further innovation could make them more economically and environmentally viable.

Bio-Based UPR Development: To reduce reliance on fossil fuels and enhance recyclability, bio-based unsaturated polyester resins are becoming a topic of interest. These resins, derived from renewable sources like plant-based oils, offer an eco-friendlier alternative. Although still relatively new, bio-based UPRs could help lower the environmental footprint of resin production while making the material more compatible with circular economy practices. Researchers are actively exploring how bio-based UPRs can be integrated into a fully circular lifecycle, from production to recycling.

Hybrid Composites for Enhanced Recyclability: Another innovative trend is the development of hybrid composites that blend UPR with thermoplastics, which are easier to recycle. By incorporating thermoplastics into the resin, manufacturers can produce materials that offer the same durability and strength as traditional UPR but with improved recyclability. These hybrid composites are gaining interest in industries where both performance and sustainability are critical, such as automotive and aerospace.

Market and Regulatory Influences on UPR Recycling

The shift toward more sustainable UPR practices is not just being driven by technological advancements but also by market demands and regulatory pressures. Consumers are becoming increasingly aware of the environmental impact of the products they use, pushing industries to adopt greener practices. In response, companies that utilize UPR are looking for ways to improve the sustainability of their products.

In addition, governments around the world are enacting stricter regulations on the disposal of plastics and other non-recyclable materials. For example, the European Union’s Circular Economy Action Plan is setting ambitious targets for recycling and waste reduction, including guidelines for plastics. These regulations are encouraging companies to invest in research and development for more sustainable UPR products and recycling methods.

What is the RTM Molding Process for Composite Material?

RTM refers to a process technology in which low-viscosity resin flows in a closed mold, infiltrates reinforced materials and solidifies into shape. It belongs to the category of liquid forming or structural liquid forming technology of composite materials. The specific method is to pre-place reinforced materials that have been rationally designed, cut or mechanized pre-formed into the designed mold. The mold needs to be sealed and tightened around the perimeter to ensure smooth resin flow. After the mold is closed, a certain amount of resin is injected. And after the resin solidifies, the desired product can be obtained by demoulding.

The RTM molding process has the following main characteristics

RTM is a closed mold molding process. The infiltration of the reinforcement and the resin is completed by the rapid flow of pressurized resin in a closed mold cavity, instead of manual infiltration in hand lay-up and spraying processes, nor expensive mechanized infiltration in prepreg and SMC processes. RTM is a low-cost, high-quality semi-mechanized fiber/resin impregnation method.

The RTM molding process uses reinforced material preform technology that is similar to the shape of the product. Once the fiber/resin infiltration is completed, it can be cured, so a low-viscosity fast-curing resin system can be used. It can also heat the RTM mold to further improve production efficiency and product quality.

The reinforced material preform in the RTM molding process can be prepared from chopped strand mat, fiber cloth, wrinkle-free fabric, three-dimensional knitted fabric, three-dimensional braided fabric, etc. And according to the performance requirements, selective reinforcement, local reinforcement, hybrid reinforcement, and embedded and sandwich structures can be used, which can give full play to the performance designability of FRP/composite materials.

The closed-mold resin injection method of the RTM molding process can greatly reduce the toxicity of harmful resin components to the human body and the environment, and meet the increasingly stringent restrictions on the volatilization concentration of harmful gases such as styrene in advanced industries.

The RTM molding process generally adopts a low-pressure injection process, which is conducive to the preparation of complex overall structures with large sizes, complex shapes, and two-sided surfaces.

According to the requirements of the production scale, RTM molds can be selected from different grades of molds such as polyester molds, epoxy molds, surface nickel-plated material molds, alloy molds, aluminum molds and steel molds to reduce costs.

Requirements of RTM technology on epoxy resin systems

Epoxy resin has low viscosity at room temperature or lower temperature, and has a certain storage period.

Epoxy resin has good wettability, matching and adhesion to reinforced materials.

The epoxy resin system has good curing reactivity and does not produce volatile matter and other undesirable side reactions during the curing reaction. The curing temperature should not be too high, and the curing speed should be appropriate.

As a high-performance composite material, epoxy resin is also required to have high heat resistance and moisture resistance, excellent mechanical properties, especially toughness. In some special applications, it should also have certain functionalities, such as low dielectric loss, high conductivity, excellent flame retardancy, etc.

High-performance epoxy resin system is still the most widely used high-performance composite matrix. Epoxy resin systems usually used to make prepregs are difficult to mold using the RTM process due to their high viscosity and short storage life. In order to be suitable for RTM molding, YQXPOLYMER launched the 9320A/B epoxy resin curing system. 9320A/B is a special epoxy resin curing system for RTM process. This system product is composed of special epoxy resin and modified amine curing agent. The 9320A/B epoxy resin curing system has the characteristics of fast curing speed, good water resistance, high hardness, good adhesion, mechanical properties of the cured material and high Tg temperature. It can be widely used in automotive composite materials for RTM molding, cultural and sports products (fishing rods, badminton rackets, golf clubs, etc.) and other carbon fiber composite materials. The RTM process has a wide range of advantages. The molded parts have high fiber system content, low porosity, low water absorption, and good mechanical properties. Conventional resins and reinforcing materials can be used in the RTM process.

Bonding Excellence: Navigating Trends in the Epoxy Adhesive Market

Adhesives are essential products that are often overlooked. They’re noticed, until they fail. If your supports aren’t correctly fused, it could bring about disjointed parts, damaged equipment, and worn-out piping systems.

So, this blog has the ins and outs of epoxy adhesives, which can help you secure the pipe supports with confidence.

What Is an Epoxy Adhesive?

From time-to-time epoxy adhesives are confused with bonding products like glue. However, they’re far more complex than most adhesives. These are often called structural adhesives These terms make their role clearer: They’re high-performance adhesives meant for applications calling for powerful bonding, such as aircraft, automobiles, aerospace technology, or heavy process piping systems.

Uses of Epoxy Adhesives Coming to process piping systems, the epoxy adhesives have a vital role to play. These systems frequently require to join unlike materials together, like composite pipe shoes and metal piping. Besides, adhesives need to hold structures together in heavy vibrations, high pressure, and corrosive environments.

An area where epoxy adhesives have advantage is when you’re including pipe supports like wear pads, pipe shoes, and Flat Plates. That’s since this mixture enables to install without welding.

Benefits of Epoxy Adhesives? • By safeguarding pipes or adding wear pads to the system, raw piping can be insulated. Suddenly, you’ve protected pipes from metal-on-metal contact deprived of the high cost of specialized labor. Also, by eliminating welding, you’ll be evading susceptible spots requiring special heat treatments. • These pipe supports can increase the life of the systems, need to be held together. These adhesives work pretty well since they are sturdy and can stand extreme environments. • An epoxy can also work as a sealant filling open gaps. This guards pipes and supports from corrosion.

Different Kinds of Epoxy Adhesives There are numerous epoxy adhesives, but they can be split into two one-component and two-component

One-Component Adhesives These more often than not come as a single paste. Though, the name can deceive a few. Though they come as only a single physical substance, they still require external elements to start the curing process. That means they require moisture, heat treatment, or special lighting for bonding.

Two-Component Adhesives These require you to blend two elements. When applied properly, the outcome is a powerful bond. Though, since two-part adhesives need mixing, there’s the likelihood for a human error.

What’s the Solution? If you desire to get the paybacks of a two-component adhesive without mixing the right ratio or getting it on the skin, use a static applicator. This loads onto a standard epoxy cartridge and brings a two-part epoxy in a flawless mixing ratio, saving the mess and guesswork that from time to time come with physically mixing two-component epoxies.

Due to the increasing demand for these adhesives in numerous industries, the total value of the epoxy adhesives will reach $13,484 million by 2030.
