It is significantly lighter than similar parts manufactured by other processes

The material is a good choice for insulation in buildings and other industrial uses. The foams are also good for the environment. There is no harm in using them. The patented technology is available in Cassel, Virginia. The company is committed to developing new technologies and products for industry and the general public. 

Structural foam injection molding is a common method of creating plastic parts that are highly durable, lightweight, and impact resistant. It has many advantages over traditional plastic injection molding processes. Its process also allows for larger part sizes than injection molding and produces parts that resist warping and fading. Here's how this method works: First, a mold is designed for a large part, Wholesale China Polymethacrylimide Foam Suppliers such as a car bumper or large furniture piece. 

The mold then introduces nitrogen gas into the barrel, which increases the density of the plastic. Another important characteristic of structural foam is its sandwich structure, with a low-density core completely surrounded by a higher-density outer layer. The result is a material that is 20% to 40% lighter than traditional materials. Its base material is a thermoplastic polymer such as polyurethane, polycarbonate, or polyphenylene oxide.

Other polymers that may be used to make structural molded parts include acrylonitrile butarene, nylon, and Noryl. One of the primary benefits of using structural foam is its reduced weight. It is significantly lighter than similar parts manufactured by other processes. Because it doesn't have a cellular core, structural foam parts can be as light as 10% to 30% lighter than comparable parts. The material is also easy to work with, enabling them to be finished much like wood.
