Shanghai Daoqin Plastics Co., Ltd.

         plastics production process in, polymer, additives, processing equipment is main/primary material conditions.

         thermoplastic property plastics use additives product types and amount relatively more, hot solid property plastics processing in remove solid need additives outer, for other additives demand versus for relatively less.

         additives use amount relatively small, generally is polymer weight separation 之几, per mille 之几. increase agent, strong/high agent, filling agent, soft agent, flame retardant and other use amount relatively large, can 达10份至数十份. additives use amount small, function significantly, can make certain property can defect relatively large or processing very difficult 而几乎失 实 use value polymer formed 宝贵 材 material.

         due to additives use, from make many fine chemical industry product obtain more has application. therefore, additives also by is “ industrial 味精”.

        按 products features selection additives

        一, improve/increase stability property additives

        即 stabilizer, is anti or polymer in processing, and use process in aging 变质. due to aging mechanism 各异, stability additives also separation is below/following type:

        1, antioxidant

        （1）自由基抑 made agent: 主 antioxidant, amine type and type;

        （2） oxidation material separation understanding agent: 辅助 antioxidant, main/primary is 硫代二羧 acid ester and acid ester, usually and antioxidant use.

        2, light stabilizer

         also is outer light stabilizer

        （1） light agent: 炭黑, oxidation zinc and 一 无 machine material;

        （2）紫 outer light absorption agent: water acid ester type, 二苯甲 ketone type, 苯并三唑 type, acrylonitrile type, type and other;

        （3）猝灭 agent: main/primary is has machine combined material.

        3, heat stabilized agent

         generally polyvinyl chloride (PVC) and chlorine ethylene copolymer use stabilizer

        （1）主 stabilizer: salt property salt, metal type and salt type, has machine combined material and other.

        （2）辅助 stabilizer: ring oxidation combined material, acid ester, more alcohol and other.

        （3） composite/compounding stabilizer: 由主 stabilizer (main/primary is metal type and salt type and has machine combined material) and stabilizer, other stability additives formed.

        4, anti agent

        绝 large more polymer for is 不敏感, due to in processing in add increase agent, lubricant, acid type heat stabilized agent and other can 滋生霉菌 material 质, from tool has easy property. anti agent chemical type type very more, 包括元素 has machine combined material, nitrogen has machine material, 二硫代氨基甲 acid salt, 三卤代甲基硫化 material, has machine material and type material and other.

        二, improvement mechanical properties additives

         improvement tensile strength, hardness, rigid property, impact strong/high degree, hot deformation property and other. main/primary below/following type:

        1, resin crosslinked agent —— separation is 辐射 crosslinked and chemical crosslinked

         chemical crosslinked using/adopting crosslinked agent, commonly used has machine oxidation material and crosslinked agent and crosslinked promote agent use, improve/increase crosslinked degree and crosslinked speed degree. ring oxygen resin crosslinked agent is solid agent, using/adopting amine and has machine acid 酐. outer crosslinked light agent belongs to crosslinked agent.

        2, strong/high agent, filling agent and coupling agent

         tool has strong/high function fiber type filling agent glass fiber, carbon fiber, metal must and other; filling agent main/primary has carbon acid 钙, 陶土, slip 石, 云母, oxidation silicon, acid 钙, acid 钙, powder and fiber and other; coupling agent is machine reinforcement material and filling agent and has machine polymer between 桥梁, can significantly improve/increase plastics machine strong/high degree, main/primary is has function property silicon and titanium acid ester type combined material.

        3, impact resistant agent —— used for improvement hard plastics products impact resistant property can

         commonly used has: MBS(methacrylic acid ester - butadiene - styrene copolymer), ABS(acrylonitrile-butadiene-styrene (ABS) copolymer)以 and CPE(chlorine polyethylene (PE)).

        三, improvement processing properties additives

        包括 lubricant, demolding agent, soft agent and other. increase agent has improvement polymer processing properties function. lubricant can improvement polymer add hot molding flow property and demolding property, 包括烃 type, acid and its amine, ester, metal and other material. demolding agent coating mold surface, make products easy demolding, make its surface light 洁, using/adopting silicon 油.

        四, soft/flexible and light additives
