COLOR FELT MANUFACTURER of ethylene and vinyl acetate random copolymer with VA content of the nature of the change: the VA content of the smaller, the closer its properties of the copolymer PE; content is, the copolymer nature closer rubber. For the purposes of plastics, VA content of about 10% to 20%.

COLOR FELT MANUFACTURER foam is COLOR FELT MANUFACTURER resin matrix while the interior has a microporous plastic products, gas makes the existence COLOR FELT MANUFACTURER foam has low density, high specific strength, can absorb the load, to insulation, sound insulation, etc. so widely used, has been greatly developed in recent years [2]. COLOR FELT MANUFACTURER bubble nucleation method can be divided into physical foaming chemical foaming method, the present study the latter. Since AC is generic organic blowing agent in the hair blowing gas maximum (of 250 ~ 300mlPg), and there is less heat release, dispersion, and the release of nitrogen-based and difficult to escape from the foam body, etc., so with AC as a blowing agent.

AC main decomposition reaction is highly exothermic, the secondary reaction is an endothermic reaction, the reaction temperature as the primary and secondary reaction temperature or less, the foaming aid ZnO added to increase the foaming temperature range , but also suppresses the AC decomposition ZnO secondary reaction, which prevent the formation of isocyanate and ammonia cause corrosion of equipment.
