Home " Product Center " AOC " AOC Palatal A 400-901 m-phenylene unsaturated polyester resin

Product Properties

Beryl A 400-901 is a general-purpose m-phenyl unsaturated polyester resin with medium viscosity and high reactivity.

major application

Brylon A 400-901 is suitable for casting products and FRP products that require high mechanical strength and high temperature and corrosion resistance, and is used in artificial stone, handicrafts, grills and pipes, ships, automobile parts, etc. It has low fracture sensitivity and thus high fatigue life. The products have low fracture sensitivity and thus have high fatigue life. It is especially suitable for products in contact with water, especially seawater. It has high resistance to water and chlorine. The main molding processes are hand lay-up, winding, casting grating and pultrusion.
