1. Polyurethane rigid core foam plastic has the advantages of light weight, high specific strength and good dimensional stability. Polyurethane rigid foam has good mechanical strength. In low temperature environment, its...
The core material foam can be divided into rigid foam, soft foam, semi-rigid or semi-soft foam. The core material foam plastic is also called porous plastic, a plastic with numerous micropores inside made of resin as the...
1. Molding process: The mold cost is relatively high. The advantage is that it can accurately ensure the thickness and size of the composite material. It has two smooth surface components. The components that usually use...
After proper high temperature treatment, PMI foam can withstand the high temperature composite material curing process requirements, so that PMI foam has been widely used in the aviation field. Medium-density PMI foam ha...
Polymethacrylimide foam refers to a foam with a C-C chain as the main molecular chain and an imide structure in the molecular side chain, which can be manufactured by a variety of methods. PMI foam is currently the heat-...
PMI foam has the following properties: 1. 100% closed cell structure and isotropic. 2. Good heat resistance, heat distortion temperature is 180~240℃. 3. Excellent mechanical properties, high specific strength and high sp...
