2023-11-13

1、 Features and main uses:

Tianrun TR-P995 is an unsaturated polyester resin (modified) synthesized from isophthalic acid, maleic anhydride, and standard diols, which has been dissolved in styrene. It has medium viscosity and high reactivity, and the pultruded products made from it have high strength, toughness, and heat resistance. Suitable for pultrusion molding process, suitable for making products such as tent poles and fish poles.
