Excellent cake release.  Lowest temperature

Polypropylene felt is used for general applications where chemical and moisture attacks other fibers

Polypropylenes offer high strength, excellent resistance to most acids and alkalis

Smoothness of fibers allows good cake release and resistance to blinding. Moisture absorption is virtually non-existent.

Excellent resistance to both mineral and organic acids and alkalis with the exception of sodium and potassium hydroxide above 110degrees.

Fair resistance to most oxidizing agents

Excellent resistance to most organic solvents with the exception of ketones, esters, and chlorinated hydrocarbons

Continuous operating temperature 194℉ (90°C)
