A Complete Guide to Choosing the Right Rubber Edge Profiles from Greendale Rubber

How to Get the Right Rubber Edge Profile

People who come into touch with bare edges are shielded by edge profiles. Additionally, edge profiles, also known as profile seals, give surfaces like car doors, machinery, and equipment a polished appearance. Selecting the appropriate rubber edge profiles is crucial, but you also need to be careful while installing profile seals. If not, these plastic or rubber goods may split or buckle.

This blog from Greendale Rubber will teach you how to buy rubber edge profiles online according to application requirements, building materials, and other factors. Additionally, you will discover some best practices for profiling and applying profile seals.

Types of Rubber Edge Profile

Rubber edge profile is often made to order according to project specifications. Rubber edge profiles are produced using techniques such as injection moulding, compression, and extrusion, which provide a clean surface finish appropriate for purchasing specifications. Typical varieties of rubber edge profiles include the following:

Accordion profile

Bulb profile

Door profile

Lip profile

Edge profile Durometer

Rubber edge profile can be composed of two types of rubber: dual durometer rubber or sponge rubber. One kind of edge profile is a bulb profile, which has a firmer retainer pushed into place over the flange and a softer bulb. A dual durometer rubber bulb profile is a good choice for low-to-medium compression force applications because it can insulate against sound and provide air, dust, water, and fluid sealing.

Materials

Neoprene and robust EDPM rubber are the two materials most frequently used to make rubber edge profiles. Due to their extreme density, both materials may be used in a variety of ways. Both materials provide outstanding resistance to abrasion and wear and tear. Both of them are perfect for usage in homes, businesses, truck cabs, and on sharp edges.

EDPM: EDPM is an adaptable, chemically and thermally resistant material that may be used to create sealing components for a variety of uses and sectors. Because EPDM moulded sealing materials provide exceptional protection against severe temperatures, they are a top choice for applications involving hot and cold temperatures.

Neoprene: For a better seal against petroleum-based compounds like oils and greases, a neoprene rubber edge profile is the better choice. Neoprene profiles can also be used as sealants against rubber and ozone-containing materials. It is important to remember, nevertheless, that neoprene does not provide the same endurance against cold conditions that EDPM provides.

PVC: This material is robust, lightweight, and resistant to abrasion. Although PVC is simple to install, it can fade in the sun and crack in the winter.

Silicon: It has a broad temperature range of thermal stability, moderate toxicity, and minimal chemical reactivity. However, dust may stick to silicone.

TPE: This is costlier than alternative edge profile materials, such as EPDM, but less prone to break in the winter than PVC. encourages recycling.

Do you want assistance selecting the rubber edge profiles online for your requirements? While material kind, durometer, and core type are significant considerations, they are not the only ones. Apart from the actual measurements, it could be necessary to indicate a certain hue or feel. The minimum bend radius and edge thickness are also important.

Extrusion What does it mean

There are a lot of different processes in the manufacturing world. One of them is extrusion. The main purpose of this process is to create products that have a fixed cross section. In comparison to other manufacturing processes, extrusion seems to be advantageous. This is because it allows creating complex cross-sections with materials that are brittle by nature. Extruded products also have a perfect finish. In addition to that, products made by solid rubber extrusion are smooth, soft, biocompatible, have transparency and are resistant to tear.

Manufacturers like Lusida Rubber Products extrude materials like Chloroprene, Butyl, Viton™, Nitrile, Neoprene, SBR, NBR, Natural Rubber and EPDM. In addition to that, the methods employed during manufacturing are approved by FDA.

Apart from solid rubber extrusion, there is sponge rubber extrusion as well. It is quite similar to the former but involves addition of chemicals during processing. This lets you use it for several applications. Most of the extruded products include extruded seals and extrusion seals with wire carrier. These are widely used for different purposes. Extruded seals are used for pumps, mills, industrial equipment, automobiles, construction, fuel tanks, electronic enclosures and much more. In fact, you would find these seals in doors and windows so that wind and water don’t enter into your house.

Spills Are Gone - Manual for Mechanical Seals

Mechanical Seals and How They Work

Maybe the most dependable depiction of mechanical seals is that they are gadgets that control spills. They close gases and fluids so whatever is inside is kept from heading outside. For example, a seal is set between the part where two pipes combine so that gases and liquids don't spill out.

Seals are accessible in different varieties, sizes, shapes, and materials. They're intended to confront requesting, outrageous conditions, like those with hugely high strain. Basic settings, for example, the lower part of a bath can likewise utilize seals.

The releases that departure from seals might be exceptionally poisonous, so they should remain tough and effective. Dealing with fixing hardware is difficult, notwithstanding, since they're straightforwardly exposed to possibly hurtful strong particles and synthetic substances.

Seals experience a great deal of grating since they're situated among joints, and erosion is something significant that adds to mileage.

Despite the fact that there are medicines that expand the life expectancy of mechanical seals, they should be supplanted at last.

The Various Kinds of Mechanical Seals

· Gaskets and Fittings

Plugs are the easiest types of seals. They might be made of elastic materials, similar to stopper or elastic. At the point when attachments are fitted into an opening, they are squeezed into that opening such a lot of that mechanical tension is made. The tension seals the opening, consequently keeping anything from getting away from the opening.

Gaskets support this instrument. In the event that the space between two items isn't totally fixed or on the other hand in the event that a joint isn't adjusted, a gasket can occupy this space so liquid or gas is totally closed.

· Hose Couplings

A few seals function as straightforward as screwing something into that two separate items fit cozily together. For instance, when a hose is in a bad way into a spigot, there's tiny opportunity that water will escape.

· Complex Seals

Obviously, a few seals are basically significantly more muddled than the above models. Shafts introduced in siphons, for example, are set up firmly inside their packaging. To ensure water stays out, a layer of oil is put between the siphon's packaging and shaft. A gasket is situated right between the shaft and the packaging with the goal that both will push against one another. This framework will bring about a strong obstruction that can endure gigantic measures of tension.

· Rib Gaskets

Ultimately, there's the rib gasket, which is utilized for fitting or joining two areas of lines. It's particularly intended for pipes that are erupted to introduce a higher surface region. There are various sizes of rib gaskets, and they're estimated by inward and external widths. Rib gaskets might fall into any of these classes: twisting injury gaskets, ring gaskets, layered metal gaskets, and sheet gaskets.

Mechanical seals are persistently improved to have a more drawn out life expectancy and endure extreme working conditions. One improvement includes the utilization of an inward pressure ring, which permits better spine pressure. One more improvement in mechanical seal innovation utilizes an external directing ring, which fills in as a pressure inhibitor.

SantopSeal uses a Thermoplastic rubber Santoprene TPE/TPV material to create custom profile extrusions of various shape and size of Seals & Gaskets as a solution to all your sealing needs.

how we made custom rubber extrusions for clients

Custom rubber extrusions are made to be small size flexible strips or large size straight bars/profiles,often made by EPDM,silicone rubber etc, the finished products series are

weatherstrip seals for vehicle,door and window(sunlight,rainstorm, cold,wind,ozone,UV etc)

edge trims for guard protection or rough parts decoration(e.g.sheet metal)

sponge/foam rubber edging for sheet metal extrusions for anti impact/vibration/collision/hard-wearing

industrial use rubber tubing,rubber strip/sheet,extruded large profiles

custom rubber extrusions manucturing workflow chart

1.Raw material preparation–compounding

Mix all raw materials to a certain proportion except ultra accelerator and vulcanizator,for the first stage mixing:banbury internal mixing. Most of the rubber extrusions requires two stage mixing/plastication:

banbury internal mixing

open mixing

2.Banbury internal mixing

Mix uniformly the crude rubber with the compounding ingredients e.g. vulcanizing agent,oil-softener,fortifier etc,and stash it for 8 hours or so,to make it

Recover the fatigue

release mechanical stress

Reduce shrinkage

Compounding diffusing uniformly

Bound rubber reinforcement between carbon black and rubber with cross-linking matrix structure

first stage rubber mixing machine–banbury mix machine

Notes:

One of the ingredients Kerosene is to change the plasticity and flexibility to be more machinable;

The largest 3 synthetic rubber producing country are: USA/Japan/Korea,especially for EPDM rubber;

Rubber straining machine can effectively wipe off the impurities of the compounding rubber

Open Mixing

Compounding with accelerant,prepare the material to be next process-calendaring molding

second stage open mixing-epdm rubber mixer machine

Extruding

The exhaust type pin cold feed extruder is the most popular extruding machine,or thread cold feed extruder is another option,for general custom rubber extrusions. Extruding Die design moulds to determine the cross section shapes,which makes extruded rubber items to be a continuous bar with constant lateral section shape.

Vulcanization

Closely followed by vulcanization(or sulfidation),via a series of curing equipment—micro wave vulcanister,hot air culcanister,hauling machine and cooling equipment.

Packaging (cutting or coiling)

After cooling then make dry,the rubber extrusions item can be cut to be a given length or packed in a roll. Small size extruded rubber items is flexible,we often call it “rubber strips”(including small diameter rubber tubing),it can be curled in a roll,then every 200~300meters per carton;

Large size extruded rubber items are not easy to bend,it is more like straight bars,we often call them “rubber profiles”,rubber extrusions profiles are usually cut into centain length bars,such as anti-collision rubber profiles;

8.Required Properties for Automotive rubber extrusions

Working conditions of automotive rubber seals are required strictly conditional especially for weathering aspect,the service life of the finished product are up to the performance index of rubber extrusion items. Important parameters of automotive rubber extrusions:

Temperature range: typical value: -35℃ to 70℃

Hardness

Tensile strength: typical value >=7Mpa

Enlongation at break   Typical value 250~350

Compression set(compression load)

Anti-ozone aging

Atmospheric aging

Resistant to paint(coating properties)

Low-temperature properties (low-temp elasticity)    typical value:keep resilient at -35℃

Installation performance(insert/pull out force)

Flocking resistance

Cohesiveness

Extrusion force for edge trims

Brittleness temperature    typical value -35℃

The above properties and its typical value applies to custom rubber extrusions for common projects of industrial use rubber extrusions, such as u channel rubber edge trims,epdm rubber tubing,house door window rubber strip seals,etc
