Description
Polyester operating temperature is 130 ℃ - 150 ℃. 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.
Maximum Continuous in Dry Conditions: 150°C / 302°F
Maximum Surge in Dry Conditions: 160°C / 320°F
Typical applications
Polyester is widely used in iron and steel metallurgy, machinery manufacturing, cement industry, wood processing and other fields of dust collection process.
