Description
SAN is a copolymer of styrene and acrylonitrile, featuring high transparency (90% light transmittance) and rigidity. However, it is more brittle than ABS and has moderate weatherability, requiring protection from prolonged UV exposure.
Key Features
1. High transparency (comparable to PS, and superior to ABS)
2. Excellent rigidity (flexural modulus≥3.5 GPa)
3. Oil/chemical resistance (resistant to grease and weak acids/bases)
4. Prone to stress cracking (avoid alcohol-based solvents)
