ASA is an opaque yellow amorphous polymer, odorless and non-toxic, and its flame retardancy can be achieved UL94HB grade, it burns slowly, and emits the smell of benzene and rubber.

The relative density of ASA is 1.05~1.09, the notched impact strength is 480~580J/m, the tensile strength is 38~48MPa, the heat deformation temperature is 85~105°C under 1.86MPa load, and it can grow at -20 Used at ~75°C, it has better high temperature resistance.

ASA maintains the good mechanical properties of ABS, and has good resistance to environmental stress cracking.

ASA chemical stability is similar to ABS, resistant to oil, hydrochloric acid, dilute acid and alkali, but not resistant to esters, ketones, aromatics, chlorinated and alcohols. Compared with ABS, ASA does not contain double bonds. It can not only resist degradation, aging, and fading caused by ultraviolet radiation, but also can prevent decomposition and discoloration by heat-resistant oxygen during processing. It is precisely because of this that ASA has become one of the best weather-resistant varieties in plastics, and its aging resistance is more than 10 times higher than that of ABS.

ASA is a kind of self-antistatic material, which can reduce the accumulation of dust on the surface of the product.

The homologues of ASA are ABS and AES, and the rubber phases are polybutyl acrylate, butadiene/styrene copolymer, and ethylene/propylene copolymer. Studies have shown that the lower the eight of the rubber phase, the higher the impact strength of the resin.
