DX Alltra is a line of premium grade, re-structured PTFE gasket material, made from only the finest PTFE resins, which are then filled and re-structured in a state-of-the-art manufacturing process. The result is a line of gasket materials that you can count on to seal almost every process chemical known, under 500°F.  Its composition reduces cold flow for greater load retention and leak free sealing. Plus, at prices well below comparable PTFE sheet materials, Alltra is simply a great gasket and a great value for fabricators and end users. Available in four styles, there's an Alltra sheet for your gasket applications.
