Shanghai Daoqin Plastics Co., Ltd.

         plastics is types pure material 质, it is many material made formed.

         its in polymer/macromolecule polymer (or combined formed resin) is plastics main/primary formed separation, in addition, is plastics property can, also need in polymer in add various 辅助材 material, filler, increase agent, lubricant, stabilizer, color agent and other, can formed is property can good plastics.

        1, combined formed resin

         combined formed resin is plastics most main/primary formed separation, its in plastics in content generally in 40%～100%. due to content large, but also resin property 质常常决定 plastics property 质, therefore 人们常 resin formed is plastics 同义词. polyvinyl chloride (PVC) resin and polyvinyl chloride (PVC) plastics, aldehyde resin and aldehyde plastics mixed is 一谈. its resin and plastics is different concept. resin is types processing polymer, it not only used for manufacturing plastics, but also also is coating material, viscous agent and combined formed fiber raw materials. plastics remove less separation 含100% resin outer, large more plastics, remove main/primary separation resin outer, also need add other material 质.

        2, filler

         filler also filling agent, it can improve/increase plastics strong/high degree and resistant thermal properties, reduce cost. 例如酚 aldehyde resin in add powder rear can large large reduce cost, make aldehyde plastics formed is most plastics 之一, meanwhile also can significantly improve/increase machine strong/high degree. filler can separation is has machine filler and machine filler type, front 者如木 powder, 碎布, and various material fiber and other, rear glass fiber, silicon 藻土, 石棉, and other.

        3, increase agent

         increase agent can increase plastics can property and soft/flexible property, reduce property, make plastics easy processing molding. increase agent generally is can and resin mixed solvent, 无毒, 无臭, for light, heat stabilized high has machine combined material, most commonly used is 邻苯二甲 acid ester type. production polyvinyl chloride (PVC) plastics 时, add relatively more increase agent can to soft polyvinyl chloride (PVC) plastics, add or less add increase agent (use amount <10%), hard polyvinyl chloride (PVC) plastics.

        4, stabilizer

         is anti combined formed resin in processing and use process in light and hot function separation understanding and bad, long use lifespan, need in plastics in add stabilizer. commonly used has hard acid salt, ring oxygen resin and other.

        5, color agent

         color agent can make plastics tool has various 鲜艳, color. commonly used has machine material and machine material as is color agent.

        6, lubricant

         lubricant function is anti plastics in molding viscous in metal mold upper, meanwhile can make plastics surface light slip 美观. commonly used lubricant has hard acid and its salt and other.

        7, antioxidant

         anti plastics in add hot molding or in high temperature use process in hot oxidation, make plastics 变黄, and other.

         remove upper additives outer, plastics in also can add flame retardant, foaming agent, anti-static agent and other, meet/satisfy different use requirements.
