Tianrun TR-887 is an unsaturated polyester resin (modified) with isophenic acid and standard diols as the main raw materials, which has been dissolved in styrene. With medium viscosity and medium reactivity, excellent mechanical properties, high thermal deformation temperature, especially suitable for winding process. FRP storage tanks and pipes reinforced with glass fiber have excellent strength and toughness.
