HY-P330BS is the most chemically resistant of PTFE material variants, and is made with 100% Virgin PTFE with Barium Sulfate as the filler. HY-P330BS is manufactured by a unique process that structures the composition into fibers - This offers excellent chemical resistance, improved performance over conventional PTFE, resistant to cold flow and creep, excellent bolt-load retention, outstanding dimensional stability under thermal stress, and resistance to wear and abrasion. HY-P330BS is suitable for use with aggressive chemicals including sodium and potassium hydroxide, hydrogen and aluminum fluoride, chrome plating solution and vinyl compounds.
