Foamed plastic profiles refer to plastic materials with numerous gas micropores made by foaming molding technology. This material has characteristics such as lightweight, thermal insulation, sound absorption, and shock absorption, and its dielectric properties are superior to those of the matrix resin.
Craftsmanship
The production of foamed plastic profiles is mainly achieved through foaming molding technology. The specific process involves dispersing a large number of gas micropores in solid plastics, which can be achieved through mechanical methods (such as mechanical stirring while introducing air or carbon dioxide) or chemical methods (adding foaming agents).
classification
Foam plastic profiles can be classified according to the cell structure and density:
According to the cell structure: closed cell foam plastic (all cells are almost disconnected), open cell foam plastic (all cells are almost connected), mesh foam plastic (cells are almost wall free).
According to density: low foaming (density greater than 0.4g/cm ³), medium foaming (density of 0.1-0.4g/cm ³), high foaming (density less than 0.1g/cm ³).
application area
Foamed plastic profiles are widely used in many fields due to their excellent performance:
Industry: Used for sound insulation and thermal insulation materials.
Agriculture: Used for insulation materials.
Architecture: Used for sound insulation and thermal insulation materials.
Transportation: Used as sound insulation, thermal insulation, and shock absorption materials for automobiles and ships.
Environmental Protection and Sustainability
The recycling and treatment of foamed plastic profiles is relatively difficult, which causes some pollution to the environment. Therefore, attention should be paid to their environmental protection and sustainability in the process of promotion and use.
