Product Details
Properties
* Impact modifier is an acrylic ester based impact modifier with a "core-shell" structure. Its core is a lightly crosslinked acrylic ester copolymer, and its shell is a methyl methacrylate copolymer, which has good compatibility with PVC. When subjected to external impact, the rubber core changes, causing the generation of silver lines and shear bands, absorbing impact energy, and exhibiting excellent impact resistance, weather resistance, and color durability under long-term outdoor exposure conditions.
* Acrylic impact modifiers are widely used in various transparent and non transparent products such as profiles, profiles, pipes, fittings, plates, films, wood plastic, etc.
