Unsaturated Polyester Resin
DS-876N
DS-Tianhe Resin Series
Tianhe Dianshi brand DS-876N is a high-temperature resistant unsaturated polyester resin. It has characteristics such as high heat distortion temperature, resistance to boiling water, good high-temperature resistance, and excellent corrosion resistance, with good wettability with fillers and glass fibers. It is particularly suitable for the production of SMC/BMC pressed sanitary ware, automotive, rail transit, electrical components, building facilities, and industrial and civilian equipment in fields that require extremely high heat distortion temperature for molded products. It is also very suitable for wide addition to various molding process resins such as hand lay-up, winding, casting, pultrusion, RTM, etc., greatly improving the product's heat distortion temperature and resistance to high temperatures, boiling water, and corrosion.
