Shanghai Daoqin Plastics Co., Ltd.

toughening agent 发现我国 plastics additives industrial is polyvinyl chloride (PVC) industrial development 起, 经 50 year construction and development, already formed is type relatively is full, production enterprise ultra- 1000家 large industry, in technology water 平, product structure, production and 科技人员 素质 and other 方面均 has long 足 进步.

    a, currently, plastics additives demand product types type type fine separation, main/primary can separation is, increase agent, flame retardant, heat stabilized agent, impact resistant agent, resistant oxidation agent, lubricant, light stabilizer and other 7 type.

    b, has type polymer/macromolecule combined material, can and resin mixed solvent, has active property 基团, 缤纷 toughening agent can and resin solid reaction, improve/increase fracture elongation and impact strong/high degree, heat deflection temperature (HDT) has decline, this type of material 质称之 is increase agent （flexibizer）, commonly used has liquid poly 硫橡胶, liquid 体丁腈橡胶, due to it and resin amount combined, can made formed structure agent, therefore will increase agent toughening agent type.

    c, plastics additives application relatively is 广泛, 如, construction, automotive, machine, 医院, chemical industry, packaging and other industry. this industry fast speed development, make for plastics additives product demand upper rise.

    d, plastics additives is plastics industrial important formed separation. 缤纷 toughening agent combined formed resin molding processing is improvement processing properties or resin property can 不足而必 must add versus additives, through processing process made formed tool has function plastics products.
