Molded PTFE Tube
Molded PTFE Tube OD: 30mm to 600mm Length: 10mm to 300mm/pc we have virgin molded ptfe tube, filled molded ptfe tube, fiber glass molded ptfe tube, graphite filled molded ptfe tube, bronze filled molded ptfe tube.
PTFE Tubes
We are the leading supplier of the ptfe tubes. The all manufacturing process is design in such a way that minimizes the cost of the production. Our ptfe tubing is appreciated and favored by the customers for their performance.
It consists of all characteristics of ptfe, which is an ideal raw material among all plastics. It has internally smooth structure, which made it so strong and flexible. It consists anti friction, anti-brokage and anti-blockage characteristic. It's highly resistant to the corrosive chemicals. It also consists of good dielectric strength and good tensile strength.
Advantages
• Smooth inner surface
• Abrasion resistance
• High temperature resistant
• High dielectric strength
• High strength against pressure
• anti-friction
• anti-corrosive
• Flexible.
• Non-contaminating
