Pet core foam plastic has advantages in environmental protection, but not all advantages. The foaming of pet core foam is pure physical foaming technology of carbon dioxide supercritical foaming, and the entire foaming process is free of emissions. Pet itself is not toxic, and pet foam will add additives during the production process, and these additives have no harmful substances and are harmless to the body. Pet foam is a thermoplastic that can be recycled and reused, but pet itself degrades for a long time and will form plastic particles.

 

 

Pet foam is mainly used for blade filling in wind power. At present, a lot of them are used. Jinfeng, Yuanjing, Mingyang, SAIC and other whole machine factories also have blades made of pet foam core material, but the blades of pet foam core material have not been verified by time in China, so some Manufacturers are still more cautious. PET foam is a sandwich structure foam, which has a certain bearing capacity, but cannot completely replace wood.

 

Because of its strength, high quality and light weight, it can be used in rail transportation. In yachts, light boats also have applications. In addition, it is also used in household furniture. It can partially replace MDF and be used as furniture board. It can resist mildew and corrosion. It is hydrophobic because of closed-cell foam. It can be used in hot and humid environments, such as bathroom shower rooms. Polystyrene foam is made of polystyrene resin as the main body, and additives such as foaming agents are added. It is a widely used buffer material.

 

It has a closed-cell structure, low water absorption, excellent water resistance, and low density, generally 0.015 to 0.03. Good mechanical strength and excellent cushioning performance. Good processability and easy molding. It has the advantages of good colorability, strong temperature adaptability, excellent radiation resistance, high dimensional accuracy and uniform structure. Therefore, it occupies a high proportion in external wall insulation, but it will emit styrene gas that pollutes the environment when it is burned. It is a Class B material in the architectural profession.
