Shanghai Daoqin Plastics Co., Ltd.

         plastics processing in add a small amount of antioxidant, can retardant or aging process, from long plastics products use lifespan.

         selection antioxidant 时, main/primary according to plastics material types type and Model/Grade, processing equipment and process conditions, its it chemical additives product types and add amount, products use ring and and other factors comprehensive 确定.

         selection industrial applications antioxidant basic below/following 原则.

         versus property

         plastics polymer and antioxidant versus property relatively 差, usually is in high temperature lower will antioxidant and polymer melt combined, polymer solid will antioxidant separation versus in polymer separation in 间. in formulation use amount scope/range inner, antioxidant in processing temperature degree lower need melt. need especially attention/notes, design formulation 时, selection solid antioxidant, light stabilizer melting point or upper 限, low plastics polymer processing temperature degree.

        迁移 property

         plastics products, especially is surface and ratio (or quality ratio)数 value relatively small products, oxidation main/primary in products surface, this need antioxidant 连续不断 from plastics products internal to products surface 而发挥 function. if toward products surface speed degree fast, amount large, antioxidant need to products surface ring in, or expand dispersion agent and products surface its it in loss 失, this type of loss 失事实 upper is can 避免, design formulation add 以考虑. antioxidant product types has selection 余 时, selection molecular weight versus for relatively large, melting point relatively high product types, and need most use ring is front 提确定 antioxidant use amount.

         stability property

         antioxidant in plastics material in maintain stability, in use ring lower and high temperature processing process in loss less, color or color, separation understanding (remove used for processing heat stabilized function antioxidant outer), and its it additives 发生不利 chemical 应, 不腐蚀 machine equipment, easy by products surface its it material 质 抽提.

         processing property

         plastics products processing 时, add antioxidant for resin degree and screw 转矩都 can can 发生改变. antioxidant for resin melt scope/range if versus relatively large, generate antioxidant or screw phenomenon. antioxidant melting point low processing temperature degree 100℃ above 时, will antioxidant made formed masterbatch, again and resin mixed combined processing products, 以避免因偏流造 formed products in antioxidant distribution and processing output/production volume decline.

         ring and property

         antioxidant 应无毒 or low 毒, powder or low powder 尘, in plastics products processing manufacturing and use in for 人体无 has function, for material, material 无危害, for gas, 土壤, water 系 无污染.

         for use film food packaging box/case, toys, one-time property liquid and other or 直接接触 food, product, medical device tool has plastics products, not only selection already through USA food and material tube/pipe 理局(FDA)检验并许 can, or 欧共体委员会 method 令允许 antioxidant product types, but also add amount 应严格 control in most large 允许限 degree inner.

         main/primary product

        ★ antioxidant 1010

         white flow property powder 末, melting point 120~125℃, property relatively low, is types relatively good antioxidant. in PP in application relatively more, is types heat stabilized property high, non combined high temperature conditions lower use additives. another, can used for its it large more resin. generally add amount large 于0.5%.
