About Blending PTFE Needle Felt: we can lower the cost by 10% – 30%.Our sales manager will advice you to choose the most suitable fabrics after we have a clear understanding of your plant. Consider of cost, the blending PTFE Needle Felts are 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 fabric. 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 it’s coefficient of friction is low, so we can easy to clean this fabric.
