Product Name:Unsaturated Polyester Resin
English Name:Unsaturated Polyester Resin
CAS No.:26123-45-5
Aliases:Unsaturated Polyester, FRP Resin
Molecular Formula:(C20H22O11)n
Physical Properties:Yellow to amber transparent viscous liquid, density 1.1~1.4 g/cm³, viscosity 0.2~2 Pa·s at 25°C, soluble in styrene, acetone and other organic solvents, insoluble in water. When mixed with an initiator, it cures into a thermosetting resin at room temperature or upon heating. After curing, it exhibits high mechanical strength, excellent electrical insulation and chemical corrosion resistance.
Uses:Mainly used to manufacture glass fiber reinforced plastics (FRP/GRP), such as ships, automotive parts, storage tanks, pipes, cooling towers, etc. Also used for making artificial stone, buttons, coatings and handicrafts. By combining with crosslinking monomers such as styrene and initiators, it can be cured at room temperature or by heating for molding.
Technical Specifications:
Acid value ≤40 mg KOH/g
Viscosity at 25°C: 0.2~2.0 Pa·s
Gel time at 25°C: 10~30 min
Heat deflection temperature after curing ≥60°C
Tensile strength ≥40 MPa
