The main component of PET core foam plastic is polyethylene terephthalate, commonly known as polyester resin. PET foam is a kind of closed-cell thermoplastic structural foam, which has certain shear and compression stren...
High-density polyethylene closed-cell high-temperature-resistant foam is a new type of waterproof material with an independent bubble structure. The appearance structure is composed of tiny foam particles. Foaming produc...
The main component of PET foam is polyethylene terephthalate, commonly known as polyester resin. PET foam has good heat resistance, mechanical strength and environmental performance, so it is widely used in construction,...
Classification of chemical principle of core foam plastic: 1. By-product gas during the polymerization process, such as polyurethane foam, when isocyanate and polyester or polyether undergo polycondensation reaction, som...
Styrofoam is flame retardant. Flame retardant foaming agent characteristics: front foaming, one-time foaming rate is 70%; high expansion, can hit 20 meters; foam stability, high compressive strength; closed cell rate up ...
Gradual degradation of high temperature resistant foam: This degradation is mainly at the high temperature of processing, and the foamed polymer contains trace moisture, acid or alkali, etc. for selective degradation. Th...
