Plastic foaming agents in the case of heating , can decomposite carbon dioxide, nitrogen, and the gas will dispersed

into the plastic melt, and form the formation of pores,chemical foaming agent can improve the apparent density and

physical properties of plastic products.

Plastic foaming agent inluding chemical foaming agent and physical foaming agents,

Chemical foaming agents for plastics mainly inlude azodicarbonamide, AC blowiing agnet, NC blowing agent,

H blowing agent, OBSH blowing agent.

Chemical foaming agent mainly be used on PVC, polyethylene, polypropylene, polystyrene, polyamide, ABS and

other synthetic materials. Widely used in slippers, soles, shoe soles, plastic wallpaper, ceiling, floor leather,
