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...
Development trend of high temperature resistant foam materials: High temperature resistant foam materials are generally materials with a guide thermal coefficient less than or equal to 0.2. The use of good insulation tec...
What are the classification of MI foam? 1. Rigid foam, that is, at room temperature, the polymers constituting the foam are crystalline or amorphous, and their glass transition temperature is higher than normal temperatu...
What types of carbon fiber composite materials should be considered? 1. Polyester resin: It is the most widely used resin in the core foam industry. Polyester resin is cheaper, has certain corrosion resistance, and is mo...
