To reinforce belts and hoses, DeWAL products lead the industry with skived thin gauge PTFE (Polytetrafluoroethylene) and UHMW-PE film (Ultra High Molecular Weight Polyethylene), the highest quality film available today. Skived films are used in many industries, including hose lining, hose cover, release liner, belt reinforcing, automotive, pressure sensitive tape, flex & microwave circuit manufacture and rubber industries. Films used as protection for hose and belt materials are made of unfilled PTFE & UHMW along with pigmented and filled PTFE & UHMW materials used in many other demanding applications.
DeWAL skived UHMW polyethylene films (Ultra High Molecular Weight) have extremely high abrasion resistance, exceeding the abrasion resistance of steel. UHMW is used in belting as a structural support layer and also in automotive rubber profiles as a wear and friction reducing layer. The natural UHMW material carries with it FDA and USDA compliance characteristics. The conductive fillers are used to enhance static dissipation in hose and other applications. DeWAL UHMW forms a superior bond directly to non-polar rubber substrates.
DeWAL PTFE films made from virgin and modified PTFE, are bonded to rubber materials to produce pump diaphragms that are used in aggressive chemical environments. Our manufacturing technologies allow us to meet customer requirements in both thickness and slit widths resulting in optimum processing efficiency. Sintered, Skived PTFE (Polytetrafluoroethylene) film is sold by the pound, foot, or meter in slit width or full width rolls and can also be supplied in sheet form. It is used in electrical applications where high temperature service rating and superior electrical properties are desired.
Overall, DeWAL products provide solutions for hose linings, hose reinforcement and belt reinforcement.
