2023-11-13
1、 Features and main uses:
Tianrun TR-31029 is an unsaturated polyester resin (modified) synthesized from phthalic anhydride, maleic anhydride, and standard diols as the main raw materials. It has the characteristics of good wettability, high reactivity, fast curing, and excellent thermal strength. The products made from it are heat-resistant and have excellent mechanical properties, high modulus, and high hardness, making them suitable for high-speed extrusion processes.
