Description

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
