ABS and ASA are similar thermoplastics. ABS is most well known in casings for domestic appliances and for toys although generally these are moulded rather than extruded. ASA was created in the 1970s with the intention of creating a similar product to ABS, but with higher levels of weather resistance.
ABS and ASA are polymers that share many similar properties. They both have high impact resistance at high and low temperatures. They share excellent rigidity and chemical resistance, and both have good adhesive properties.
ASA extrusions are best known for their high UV and weather resistance.
