PC ASA ALLOY
product details
Engineered to Outlast the Sun — The Outdoor-Grade Alloy You Can Trust for a Decade
Material Overview
ASA was developed for one specific reason: to give engineers an ABS-like material that would not yellow, chalk, or embrittle under sustained sunlight. PC/ASA elevates that legacy by combining polycarbonate’s structural backbone with ASA’s acrylic-rubber UV stability, creating an alloy purpose-built for outdoor service.
Where standard PC/ABS surrenders within months of unprotected sun exposure, PC/ASA continues to perform for years, retaining both mechanical integrity and surface appearance. Renhong’s PC/ASA compounds are formulated for applications where 5 to 10 years of unprotected outdoor service is the baseline expectation, not the upper limit.
Key Features
🌞 Strong UV Stability
Retains over 90% impact strength after 2,000+ hours QUV exposure (ISO 4892-3) — outperforming standard PC/ABS in outdoor service.
🎨 Long-Term Color Retention
ΔE color shift below 3.0 after equivalent five-year outdoor exposure in pigmented grades.
💪 Robust Impact Performance
Maintains over 30 kJ/m² Izod impact strength after weathering, helping reduce embrittlement common to PC/ABS outdoors.
🌡️ Heat Resistance
HDT up to 110°C supports stability under solar heat loads and against lamp ballast warmth.
🌊 Humidity & Hydrolysis Performance
Performs reliably in coastal and tropical climates where polyester-based alloys may degrade.
