What is general unsaturated polyester resin ?


General unsaturated polyester resin is a chemical, mainly used for casting, molding and glass fiber reinforced composite materials. Manufacturing of car and dinghy shells, containers, structural parts and electrical insulation products.

characteristic

In the formula, R′ is an alkylene group of a dihydric alcohol; R is an alkylene group or an arylene group of a saturated dibasic acid (drunk); and H 3 is an alkylene group or an arylene group of an unsaturated dicarboxylic acid (drunk). . Pure resin (excluding styrene) at room temperature [1]

Under the light yellow solid, relative density}.n a 1.15, melting temperature so a}} r, soluble in ketones and aromatic solvents, insoluble in water. Dipropylene, ethylene glycol and other glycols with phthalate L} F3, maleic acid (with dicarboxylic acid and other dihydric acid C drunk condensation) obtained by adding styrene, polymerization inhibitors, stabilizers Get a cat-like liquid resin. With styrene as a cross-linking agent, it can be cured at room temperature under the action of the initiator Liu Yi. Mainly used for casting, molding and glass fiber reinforced composite materials. Manufacturing of car and dinghy shells, containers, structural parts and electrical insulation products.
