Unsaturated Polyester Resin
TH-450-1
TH - Tianhe Resin Series
Tianhe TH-450-1 is a thickening type of bisphenol A epoxy vinyl ester resin. After rubber modification, the resin has ultra-high impact resistance and fatigue resistance, while also providing excellent thickening effects, making it suitable for molding processes such as SMC and BMC. Compared to similar types of resins, TH-450-1 has higher impact resistance, better wettability, extremely low volume shrinkage, and good processability.
