Overview
ALITA 565 Halogen-Free Low-Smoke Flame-Retardant Resin
Category：Flame Retardant ResinCode：ALITA 565
Applications
ALITA 565 is an additive-type flame-retardant unsaturated polyester resin reinforced with high-efficiency composite flame retardants. It is halogen-free and pre-dissolved in styrene.
- Core Features: Low smoke, low toxicity, high flame retardancy, and excellent self-extinguishing properties. Complies with TB/T 3138-2006 and German standard DIN 5510-2.
- Process Advantages: Combined excellent handling performance with superior mechanical properties.
- Applications: Widely used in FRP products requiring stringent flame retardancy. Recommended for buses, trains, subways, light rails (interior components), and the construction industry.
