EXPANDED PTFE SHEET - EPTFE SHEET
Description:
Expanded PTFE Sheet is made from 100% virgin PTFE with biaxially oriented,and more strength than ptfe joint sealant. it is white color,peak temperature 310℃,In possession of the characteristics of self-lubrication, low coefficient of friction and widely chemical corrosion resistance with good resistance of pressing, cold flow,and creep relaxation.
Advantage:
• Gasket making convenient.
• 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.
• network structure, reduce the cold flow deformation.
• Clean, from dust-free workshop.
