Polyester operating temperature is 130 ºC - 150 ºC. Polyester has excellent insulation, wear resistance, high strength and good thermal stability. But polyester is easy to hydrolyze. It is stable for general organic solvents, good for weak alkali resistance and general for strong alkali resistance. Typical applications Polyester is widely used in iron and steel metallurgy, machinery manufacturing, cement industry, wood processing and other fields of dust collection process.
