PVC Window Welding Application Spotlight

Application: DuraLam® fabrics and tapes are used in the vinyl window industry on the welders that bond the vinyl extrusions of new and replacement windows to prevent the hot PVC from sticking to the plates. The tapes cover the platen, where the miter of the window gets heated to weld it to the opposite vinyl piece. The fabrics are fabricated into pad covers. These pads cover most of the platen and are attached with a tong. The major difference between the two products is that the tape is smaller and more difficult to change and remove. Pads can be changed by a machine operator in less than 5 minutes. While it can take at least an hour to remove and change the tape and typically requires someone in the maintenance department.

• Solution: The ideal products for this application are AFC DuraLam® 25-05 fabric and 255-05GGS. Both products are specifically engineered to maximize product life, while minimizing down time in the welding production process. Our proprietary coating formulation was developed to reduce abrasion, increase lubricity and prevent leaching into the materials. In tests carried out in the PVC window industry, our products have been shown to last significantly longer than equivalent products from other manufacturers. We can supply product in full width, slit rolls or fabricated pieces.
  AFC’s 25-05 and 255-05GS materials are lasting 25% to 50% longer than competitive products.
