plastics foaming agent （ also 称起泡 agent ）　
指 can promote resin generate foam formed or structure material 质. foaming agent can separation is material foaming agent and chemical foaming agent large type.

　　(1) material foaming agent: also is property foaming agent. its in, gas foaming agent has gas, oxidation carbon and nitrogen gas and other, property liquid foaming agent has fluorine 里昂, low carbon 烷烃, and alcohol and other. in addition, also has can solvent property solid 体, water solvent property polyethylene (PE) alcohol and other. material foaming agent widely used in production foam plastics. it 们不污染 products, price 便宜. generally using/adopting low has machine liquid 体.

　　(2) chemical foaming agent: also is separation understanding property foaming agent. used for plastics in generate chemical foaming material 质, its separation understanding temperature degree and polymer melt temperature degree versus 近, in hot function lower separation understanding generate gas 体, make plastics foaming. generate gas 体应无毒, 无腐蚀 property, easy property. large separation thermoplastic property plastics can use chemical foaming agent foaming. chemical foaming agent separation machine foaming agent and has machine foaming agent 2 types. machine foaming agent has carbon acid hydrogen 钠, carbon acid hydrogen and other, hot separation understanding generate oxidation carbon or gas; has machine foaming agent main/primary has nitrogen combined material, nitrogen 二异丁腈, nitrogen 二甲酰 amine （即 foaming agent AC）, 碘酰肼化 combined material, nitrogen combined material, 亚硝基化 combined material, nitrogen combined material and other, can separation understanding generate nitrogen gas, oxidation carbon or gas. its in commonly used foaming agent nitrogen 二甲酰 amine color crystallization, separation understanding material 无毒, 无臭, 不污染, color, has self-extinguishing property. used for polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PP) and other foaming.
