        (2)不 effect/influence plastics resistant water property, chemical resistant product property, weather resistance, heat resistant property and other;

        (3)不 reduce plastics physical properties;

        (4) can a large amount of filling;

        (5) versus for density small, for products density effect/influence large;

        (6) price versus for low 廉.

        2, reinforcement modified

         reinforcement measures: through in add glass fiber, carbon fiber and other fiber material 质.

         reinforcement 效果: can obvious improvement material rigid property, strong/high degree, hardness, heat resistant property,

         modified defect effect/influence: 但 very more material 会导致 surface defect and fracture elongation reduce.

         reinforcement principle:

        (1) reinforcement material tool has relatively high strong/high degree and modulus;

        (2) resin tool has many solid has excellent material 理, chemical (corrosion resistant, insulation, resistant 辐照, resistant high temperature and other) and processing properties;

        (3) resin and reinforcement material composite/compounding rear, reinforcement material can to increase resin force or other property can, resin for reinforcement material can to bonding and 传递载荷 function, make reinforcement plastics tool has excellent property can.

        3, toughened modified

         has relatively more material tough property 不够, 太脆, can through add tough property relatively good material or ultra- fine machine material, increase material tough property and low temperature use property can.

         toughening agent: is reduce plastics hard rear property, improve/increase its impact strong/high degree and elongation add resin in types additives.

         commonly used toughening agent —— more is maleic anhydride grafted compatibilizer:

         ethylene -醋 acid ethylene ester copolymer (EVA)

         polyolefin elastomer (POE)

         chlorine polyethylene (PE) (CPE)

         styrene - butadiene thermoplastic property elastic property (SBS)

         ternary 乙丙橡胶(EPDM)

        4, flame retardant modified

         in electronics electrical appliances, automotive and other very more industry requirements material has flame retardant property, very more plastics raw materials flame retardant property relatively low. improve/increase flame retardant property can through add flame retardant achieve.

         flame retardant: also flame resistant agent, resistant agent or anti agent, easy polymer flame resistant property function property additives; it large more is cycle table/sheet in 第ⅤA(磷), ⅦA(bromine, chlorine) and ⅢA(锑, aluminum)族元素 化 combined material.

         tool has function combined material, combined material and iron combined material and other flame retardant 范畴, main/primary suitable for has flame retardant demand plastics, or anti plastics especially is polymer/macromolecule type plastics 燃烧. make its time growth, self-extinguishing, difficult 以点燃.

         plastics flame retardant rating:

        由HB, V-2, V-1, V-0, 5VB toward 5VA逐 grade increase.

        5, weather resistant modified

         generally plastics in low temperature lower resistant can force, due to plastics solid has low temperature property, make plastics in low temperature lower 变脆, for/regarding very more in low temperature ring lower use plastics products, generally requirements its tool has resistant property.

         weather resistance: is plastics products to cationic light 照射, temperature degree 变化, 风吹雨淋 and other outer conditions effect/influence, 而出现 褪 color, color, crazing, powder and strong/high degree decline and other series aging phenomenon. 紫 outer 线照射 is make plastics aging key/critical factors.

        6, modified alloy

         plastics alloy is utilizing material blending or chemical grafting, copolymer methods, will types or multiple material made formed high property can, function 化, specialized types new material, to improvement types material property can or tool types material features 目. it can improvement or improve/increase has plastics property can reduce cost.

         general purpose plastics alloy: 如PVC, PE, PP, PS alloy use 广泛, production technology already by 普遍掌握.

         engineering plastics alloy: 泛指 engineering plastics (resin) blending material, main/primary 包括以PC, PBT, PA, POM（ polyoxymethylene (POM) ）, PPO, PTFE（ PTFE ） and other engineering plastics is blending system , and ABS resin modified material.
