type of polymer material formed by a large number of gas micropores dispersed in solid plastic. It has the characteristics of light weight, heat insulation, sound absorption, shock absorption, etc., and its dielectric properties are better than those of the matrix resin, and it has a wide range of uses. Almost all kinds of plastics can be made into foam plastics, and foam molding has become an important field in plastic processing. Also called porous plastic. Plastic made of resin as the main raw material with countless micropores inside. Lightweight, heat-insulating, sound-absorbing, shock-proof and corrosion-resistant. There are soft and hard materials. It is widely used in thermal insulation, sound insulation, packaging materials and car and ship shell making. Foam plastics, microporous plastics, plastics that contain countless micropores throughout.
Plastic with many tiny pores inside. It is produced by mechanical method (injecting air or carbon dioxide while mechanically stirring to make it foam) or chemical method (adding foaming agent). It is divided into two categories: closed cell type and open cell type. The pores in the closed-cell type are isolated from each other, while the pores in the open-cell type are connected to each other and have no floating properties. It can be made of polystyrene, polyvinyl chloride, polyurethane and other resins. It can be used as thermal insulation and sound insulation materials and has many uses.
Foam plastic is a type of polymer material formed by a large number of gas micropores dispersed in solid plastic.

Almost all kinds of plastics can be made into foam plastics, and foam molding has become an important field in plastic processing. Structural foam plastics developed in the 1990s are characterized by foaming in the core layer and non-foaming in the cortex. They are hard on the outside and tough on the inside. They have high specific strength (strength per unit mass) and consume less material. They are increasingly used to replace wood. in the construction and furniture industries. The success of chemical or radiation cross-linking foaming technology of polyolefins has greatly increased the production of foam plastics. Foam plastics made by blending, filling, reinforcing and other modified plastics have better comprehensive properties and can meet the needs of various special purposes. For example, glass fiber reinforced polyurethane foam made by reaction injection molding has been used as structural components of aircraft, automobiles, computers, etc. Foam made of polybenzimidazole filled with hollow glass beads is lightweight and resistant to high temperatures. Already used in spacecraft.
