Shanghai Daoqin Plastics Co., Ltd.

  hot melt adhesive formed separation: basic resin, increase viscous agent, viscosity adjustment agent and antioxidant and other formed separation formed.

      1. basic resin: hot melt adhesive basic resin is ethylene and acid ethylene in high temperature high pressure lower copolymer formed, this type of resin is hot melt adhesive main/primary formed separation.

      2. increase viscous agent: increase viscous agent is hot melt adhesive main/primary additives 之一. in its in add increase viscous agent can improve/increase flow property and for by viscous material lubricating wet property, improvement adhesion property can, to adhesion strong/high degree.  

      3. viscosity adjustment agent: is hot melt adhesive main/primary additives 之一. it is is increase flow property, adjustment solid speed degree, this can to fast speed adhesion solid 目.  

          4. antioxidant: add amount antioxidant is is anti hot melt adhesive aging.  

          hot melt adhesive formed separation:

          hot melt adhesive remove above types raw materials outer, also can according to gas temperature, 区 差别配 upper 一 适 combined cold belt/tape gas temperature resistant agent or combined hot belt/tape gas temperature resistant hot agent:  

          1. resistant agent main/primary function is improve/increase hot melt adhesive property, add resistant agent can anti 止冬天 gas temperature low formed open time and solid time front, effect/influence 书册 黏 force, add can add a small amount of dilute （ generally is 2% left right ）.        

          2. resistant hot agent main/primary function is improve/increase hot melt adhesive hardness, increase basic resin formed separation and other. add resistant hot agent can anti due to gas temperature high and 区 差别, formed 胶体不 easy solid and cooling type effect/influence quality and appearance 效果.
