HY-P330SI is made with 100% Virgin PTFE with Silica as the filler. Compared to conventional Virgin PTFE, this gasket material is suitable for considerably higher pressure and temperature applications. HY-P330SI is ideal for standardisation because of excellent chemical resistance and mechanical characteristics. This material offers resistant to cold flow and creep, excellent bolt-load retention, outstanding dimensional stability under thermal stress, and resistance to wear and abrasion.
