1. High Gloss and Surface Finish
PMMA/ASA granules exhibit exceptional surface brightness due to PMMA's inherent transparency and ASA's rubber-like phase, which enhances light reflection. This property allows for a "paint-free" finish, mimicking the aesthetic of traditional painted surfaces without environmental pollutants .
2. Weather Resistance
The ASA component provides superior UV resistance, maintaining color stability and mechanical properties under prolonged UV exposure. PMMA/ASA alloys resist discoloration, cracking, and fading, even in harsh climates, making them ideal for outdoor automotive components .
3. Impact and Chemical Resistance
The blend of PMMA and ASA improves toughness compared to neat PMMA. ASA's rubbery phase (acrylate-styrene-acrylonitrile) enhances impact resistance, while PMMA contributes rigidity. The alloy withstands mechanical stress and resists chemicals like acids, alkalis, and solvents .
4. Thermal Stability
PMMA/ASA alloys exhibit good
heat resistance , though additives or copolymer modifications (e.g.,
PC blends) may be required for higher-temperature applications .
