Application Prospect Of High Strength Foam Material

High-Strength foam materials are gaining market share in markets including transportation, electronics, healthcare, industrial equipment, consumer appliances, construction, boots, and sporting goods. The main reasons are the plastic's lighter weight and cushioning properties of traditional foams, plus high strength, heat and flame resistance, damping properties, chemical resistance and biological inertness.

Core Foam High-performance firing polymers include polyurethanes, polyolefins, silicones, fluoropolymers, benzene-based polymers, and other engineering polymers. Some of these materials have superior mechanical properties, heat resistance and chemical stability. Other materials use molecular chain chemical modification, cross-linking treatment or add special fillers to improve the performance of the material. Core Foam High-performance foams are fired by standard methods, such as chemical blowing agents and physical blowing agents.

High-performance foams are competitive with non-foamed plastics, metals, natural or synthetic rubbers. Foam materials can be applied to gaskets, sealing products, heat shields, shock and vibration gaskets, auxiliary equipment and electromagnetic shielding devices for EMI/RFI. In fact, there is no accurate definition of high-performance foam materials, so it is difficult to estimate the market share of its products.

After proper high-temperature treatment, it can withstand the high-temperature composite material curing process requirements, which makes the foam widely used in the aviation field. The medium-density foam has good compression creep properties and can be cured in an autoclave at a temperature of 120oC -180oC and a pressure of 0.3-0.5MPa. PMI foam can meet the creep performance requirements of the usual prepreg curing process, and can realize the co-curing of the sandwich structure. PMI foam as an aerospace material is a uniform rigid closed-cell foam with basically the same pore size.
