Product classification
TR-P792 Unsaturated polyester resins
TR-P792 Unsaturated polyester resins
Features and main purposes:
TR－P792 is a kind of unsaturated polyester resin synthesized with main raw materials of phthalic anhydride, maleic anhydride and standard diatomic alcohol, having dissolved in styrene.It has medium viscosity and high reactivity. Pultrusion products made with it have high strength, good toughness and good heat resistance. It is suitable for pultrusion molding process, suitable for making tent pole, fishing rod and other products.
