Polipropileno (PP)
High Strength, Excellent Resistance.
Polypropylene Felt: Temperature, Resistance, and Finishes
Polypropylene Felt: Normal maximum continuous operating temperature is 170°F. 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. This media has very good resistance to both mineral and organic acids and generally good resistance to alkalis with the exception of sodium and potassium hydroxide above 200°F. Good resistance to most reducing agents. Polypropylene also has fair resistance to most organic solvents with the exception of ketones, esters, and chlorinated hydrocarbons.

Polypropylene Felt Common Finishes
Singed(SIPP): el fieltro se chamusca por el lado del pastel de polvo para mejorar la liberación del pastel. El proceso consiste en exponer las fibras superficiales a una llama abierta que derrite los extremos sueltos de las fibras a los que podrían adherirse las partículas de polvo.
Glazed (GLPP) – This process involves running the felt through two heated rollers to melt back the loose fiber ends improving the cake release. The process can also compress the felt to smooth the surface, further improving the cake release.
SlyTech-01 (ST-01) – Oleophobic -water and oil repellent finish. SlyTech-01 is a complete PTFE bath which provides an excellent cake release finish to each fiber. This finish is cheaper and more durable than a membrane that can be easily scratched. Click here for more information on ST-01.
