About Blending PTFE(Teflon) Needle Felt: we can lower the cost by 10% – 30%. Our sales manager will advise you to choose the most suitable fabrics after we have a clear understanding of your plant. Consider cost, the blending PTFE Needle Felts is more economical. After our calculation, we can lower the cost by 10%-30%. PTFE(Teflon) Needle Felt is one of the most excellent chemical fiber fabrics. This material has acid-alkali resistance of various characteristics of organic solvents, almost insoluble in all solvents. At the same time, PTFE fabric has great heat-resistance and its coefficient of friction is low, so we can easy to clean this fabric.
