Felt
LONGWOOD operates the only known dedicated PTFE needle felt operation in the world today. All of our felt products are made from 100 percent PTFE fibers or PTFE polymer. Our proprietary process allows LONGWOOD to align fibers and lock them into high strength felts. Since we strictly use PTFE product in our manufacturing process, there is no chance of cross contamination by other sub straights.
