.Introduction:

ACR-LP40 and ACR-LP21 are the copolymer, which is formed by the ACR monomer with latex, and they are also high molecular weight polymer with multi-layer structure self developed by us.

 

 

When PVC injection molding uses macromolecular weight LP21, LP40 to be possible to prevent effectively "spraying" and "the runner white halo" the phenomenon occurrence, simultaneously enhances the injection speed, enable the product surface smoothly, to have the gloss, is advantageous in the injection molding physics performance enhancement

 

LP40 is equal to Japanese KANEKA PA40
