FAQ

What causes UV degradation in plastics?

UV radiation breaks polymer molecular chains through photo-oxidation, causing embrittlement, surface chalking, color fading, and loss of mechanical properties. The degradation rate depends on polymer type, stabilizer system, and exposure conditions.

How long do UV resistant plastics last outdoors?

UV stabilized PP with carbon black can last 5-10+ years, while ASA alloys maintain performance for 10+ years in automotive exterior applications. Actual lifespan depends on UV intensity, temperature, and chemical exposure.

What is the difference between UV resistant PP and ASA?

UV PP uses additives (carbon black, HALS, UV absorbers) for protection and is cost-effective. ASA has inherently weatherable acrylic rubber phase, providing superior gloss retention and impact resistance at higher cost.

How is UV resistance tested?

Common methods include QUV accelerated weathering (UVB-313 or UVA-340 lamps), xenon arc exposure testing, and outdoor Florida/Arizona exposure. Performance is evaluated by color change (ΔE), gloss retention, and mechanical property retention.

Can UV masterbatch be added to existing materials?

Yes. UV masterbatches are designed for let-down compounding at 2-5% loading. They can be added during injection molding or extrusion. However, optimum performance requires matching the stabilizer system to the base resin and application requirements.
