Expanded PTFE Joint Sealant is made from 100% white pure virgin imported PTFE resin combined with a continuous self-adhesive strip for easy application.
Advantage:
• Easy installation,cheap cost.
• Low requirement for the bolt pretightening force.
• High temperature resistance, long service life.
• Ideal for damaged flanges, irregular flanges, and glass-ceramic flanges.
• No pollution for fluid.
• Chemical corrosion resistance.
• Excellent flexibility,few cold flow deformation.
• Clean, from dust-free workshop.
