Unsaturated Polyester Resin

TH-450

TH - Tianhe Resin Series

Tianhe TH-450 is a thixotropic bisphenol A epoxy vinyl ester resin. After modification with anhydride, the resin exhibits excellent thickening effects, along with good mechanical strength and resistance to chemical corrosion, making it suitable for molding processes such as SMC and BMC. Compared to similar types of resins, TH-450 has superior wettability, extremely low volumetric shrinkage, and good processability.
