Features & Benefits
Halogen-Free Flame Retardancy
Tairilite AC3830 meets UL 94 V-0/5VA standards (1–3 mm thickness), eliminating toxic fumes during combustion. This ensures compliance with global safety regulations for electronics and lighting enclosures.
Superior Light Diffusion & UV Stability
Optimized for light-managing applications, its built-in UV resistance prevents yellowing and maintains optical clarity outdoors (UL 746C f1-rated). Perfect for long-life diffusers exposed to sunlight.
Balanced Flow & Toughness
With a melt flow index of 12 g/10 min (ISO 1133) and Charpy impact strength of 70 kJ/m², it enables intricate molding while resisting fractures—reducing scrap rates in thin-walled designs.
Use & applications
FAQs
The supplied ISO TDS lists “Halogen free” in the features.
UL Product iQ for AC383(x) lists UL 746C f1 outdoor suitability. The ISO TDS also lists UV resistance. This makes it suitable for outdoor or UV-exposed applications, subject to final product validation.
UL Product iQ for AC383(x) lists V-0 at 1.0–3.0 mm and 5VA at 3.0 mm, in ALL colors, with f1. The ISO TDS lists V-0 1 mm and 5VA 3 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 260–320°C, rear zone 250–290°C, mold temperature 70–100°C. Do not exceed 330°C to avoid degradation.
It is a light-diffusion, mid-flow, UV-resistant, halogen-free flame-retardant grade. It is often used for light-diffusion covers, LED lighting parts, and outdoor housings.
