TR886 is a modified unsaturated polyester resin synthesized from phthalic anhydride, maleic anhydride, and standard diols, dissolved in styrene. It exhibits medium viscosity and reactivity, excellent mechanical properties, and a high elongation at break, making it particularly suitable for winding processes. Glass fiber reinforced fiberglass tanks and pipelines exhibit excellent strength and toughness.
