      TR-86A Unsaturated Polyester Resin (Modified)

      2023-11-13

      1、 Features and main uses:

      Tianrun TR-86A is an unsaturated polyester resin (modified) synthesized from phthalic anhydride, propylene glycol, and a small amount of neopentyl glycol as the main raw materials, which has been dissolved in styrene. It has low viscosity and moderate reactivity, and excellent mechanical properties. Used for injection molding handicrafts, especially suitable for making artificial stone products, with excellent strength, toughness, water resistance, and weather resistance.
