Use & applications
Features & Benefits
Superior Flame Retardancy
It achieves UL94 V-0 rating at just 2.5mm thickness, ensuring critical fire safety in electrical components. Eliminates risks in high-heat environments.
Crystal Clarity + UV Stability
It maintains transparency and resists yellowing under sunlight, perfect for outdoor use. Reduces part replacement costs long-term.
Eco-Friendly & Process-Ready
Halogen-free formulation meets global environmental regulations. Mid-low flow simplifies injection molding with minimal shrinkage (0.5–0.7%).
FAQs
The supplied ISO TDS lists “Halogen free” in the features.
UL Product iQ for AC385(x) lists UL 746C f1 outdoor suitability. The ISO TDS also lists UV resistance. This supports outdoor use, subject to final product validation.
UL Product iQ for AC385(x) lists V-0 at 2.5–3.0 mm, in NC/WT colors, with f1. The ISO TDS lists V-0 2.5 mm. Verify the exact thickness and color.
The processing guide recommends pre-drying at 120°C for 4–8 hr. Nozzle and middle zones are 250–300°C, rear zone 240–280°C, mold temperature 70–100°C. Do not exceed 320°C.
It is a transparent, flame-retardant, mid-low-flow, UV-resistant, halogen-free grade. It is often used for transparent covers, lenses, and light guides requiring V-0 and outdoor suitability.
