Taconic PTFE Coated Advanced Engineered Composite Materials

PVC Welding

The manufacture of vinyl extrusions into frames for windows and doors requires a durable nonstick material during the welding process. PTFE tape or fabric covers the heated platens which allows heat to form the joint weld while preventing hot PVC from sticking to the weld plates. Taconic’s TacWeld fabric and tape are chemically inert, temperature and abrasion resistant and provide superior release which allows end users to melt the angled edges of the uPVC profile and press them together to form a clean weld in a window or door frame. TacWeld is engineered for more efficient production. Formulated for increased wear, abrasion, cut-through and puncture resistance along with temperature resistance up to 500 °F/260 °C, TacWeld’s product life is maximized to reduce machine down time. High weld quality means an improved finished product which also leads to higher production efficiency.
