PTFE Virgin Tubing

PTFE Virgin Tubing

PTFE Tubing Can Be Used With Virtually All Industrial Solvents, Chemicals & Corrosive Materials, And Can Be Used In Processes At Elevated Temperature. Working Temperature: -240°C ~+260°C Application: Electrical Insulation, Air Sampling, Chemical Transfer, Spray Painting, Pulp & Paper Processing, Food And Beverage. 

- PTFE products have excellent dielectric performances in a wide range of frequencies and temperatures. The dielectric strength changes according to the thickness and decreases when the frequency increases, with no substantial alterations up to 260°C.

- PTFE is practically inert to all chemical products, except for some alkaline metals, for example, clorotrifluoruro and for basic fluorine at high temperatures and pressures.

- PTFE is considered one of the most stable materials from the thermal point of view. Up to a service temperature of 260° C PTFE does not change its own physical and molecular properties.

- The compressive strength at a certain predetermined compression value is one of the most significant mechanical characteristics of PTFE, in a wide range of service temperatures. Flexibility strength, plastic memory and hardness, are additional characteristics of PTFE products.

- There are five basic techniques:

It is the most used processing method by which small or massive cylindrical, rectangular and sheet shapes of PTFE are moulded at room temperature and sintered in electrical ovens.

It is usually utilized for mass production of small parts with fairly simple geometry.

PTFE can be compression moulded under pressure and heat applied simultaneously followed by cooling. This process can be used to produce unfilled and filled resins almost free from porosity and with enhanced mechanical properties.

In contrast to standard compression moulding process, isostatic pressing, thanks to elastic mould, achieves compaction from all directions. With this process also complicated shapes can be processed and the final part shows isotropic properties.

It is the only continuous process for manufacturing cylindrical parts and simple profile. Compaction and sintering steps are performed simultaneously into the extruder. In general extruded parts are less performant in comparison to compression moulded parts.
