θ THETA - PTFE LAB / PTFE Thin Wall Tubes

Thin Wall Tube

Thin Wall Tube

Technical specifications
Standard product range consists of a set of thin wall tubes made by using natural PTFE raw material.
Inside diameter: from 1,5 mm to 26 mm.
Wall thickness: from 0,5 mm to 3,0 mm.

Length: based on diameter and wall thickness. For market most requested diameters, standard length coils are supplied: in 25 meters, 50 and 100 meters.

Owing to state of the technology art plants is able to produce, for some diameters, coils with lengths that can vary from 150 to 1,000 meters.

Industrial sectors
• Fluid, gas and other materials transport industry
• Electronic and electrical industry
• Automotive and motorcycle industry
• Semiconductor industry

Upon request DIFLON can produce TWT with custom specifications such as:
diameter and tolerance as requested by the client’s drawing, calibrated outside diameter, FDA raw materials, pigmented raw material available in several colours (ROHS free), antistatic and/or special additive fi lled raw materials, different shape sections, hoses cut at specific measure and/ or treated as requested by the client’s drawing.
