ASA brief introduction

2018-09-04

Asa 003

ASA is the acronym for acrylate rubber modified styrene acrylonitrile copolymer. ASA is a terpolymer that can be produced either by a reaction process of all three monomers or by a graft process.

ASA is usually made by introducing a grafted acrylic ester elastomer during the copolymerization of styrene and acrylonitrile, known as SAN. The finely divided elastomer powder is uniformly distributed and grafted onto the SAN molecular chains. The outstanding weatherability of ASA is due to the acrylic ester elastomer.

ASA polymers are amorphous plastics, which have mechanical properties similar to those of the ABS resins. However, the properties of ASA are far less affected by outdoor weathering.

ASA resins are available in natural, off-white, and a broad range of standard and custom-matched colors. ASA resins can be compounded with other polymers to make alloys and compounds that benefit from ASA's weather resistance.

ASA is used in many products including lawn and garden equipment, sporting goods, automotive exterior parts, safety helmets, and building materials.
