What is styrene acrylonitrile copolymer?

Styrene acrylonitrile copolymer (SAN) is a thermoplastic polymer made up of styrene and acrylonitrile monomers. SAN's chemical composition typically consists of around 70-80% styrene and 20-30% acrylonitrile.

SAN is known for its strong resistance to impact, chemicals, and high temperatures. It's used in a wide variety of applications, including electronic equipment, automotive parts, and household items such as kitchenware and toys. SAN is often used in place of other materials because of its strength, transparency, and durability.

Some of the benefits of SAN include:

1. High thermal stability: SAN can withstand high temperatures without degrading or warping.

2. Excellent chemical resistance: SAN is resistant to organic solvents, acids, and bases.

3. Good impact resistance: SAN can absorb energy and distribute it across a wider area, making it more resistant to impact than other plastics.

4. Easy to process: SAN can be easily molded and extruded, making it a popular choice for manufacturing complex parts.

Overall, styrene acrylonitrile copolymer is a versatile, strong, and durable material that's widely used in various industries.
