Unsaturated Polyester Resin

TH-480

TH - Tianhe Resin Series

Tianhe TH-480 is a rubber-modified bisphenol A epoxy vinyl ester resin. After rubber modification, the resin has excellent impact resistance and elongation at break, as well as good mechanical strength and fatigue resistance. Compared to similar types of resins, TH-480 has outstanding impact resistance, superior mechanical properties, lower volume shrinkage, and good processability.
