Technical Upgrade of Modified PTFE Sealing Materials for Corrosive New Energy Working Conditions

     Industrial material R&D data shows nanographite-modified PTFE sheets and braided packing deliver over 60% improved creep resistance, with long-term service temperature range expanded to -20℃ ~ 260℃. They stably fit sealing applications for lithium production pipelines and chemical reactor pumps & valves. High-purity modified PTFE sealing products are listed as key promoted categories in the National New Material Catalogue. Major domestic refining and new energy enterprises gradually launch localized procurement bids for sealing components to substantially cut costs of imported purchases.

     With advantages of non-toxicity, full medium corrosion resistance and low friction wear, modified PTFE packing and gaskets are gradually replacing traditional rubber seals to become standard fluid sealing solutions for new energy and fine chemical sectors.
