1. Mechanical Benefit and Properties: FEP tubing has good flexibility in the thin-walled portion and relative rigidity in the thick-walled portion. the flexural modulus of FEP tubing decreases significantly with increasing temperature, up to a maximum continuous service temperature of 400°F (204°C). fEP tubing has a very low coefficient of friction, but it is slightly higher than that of Teflon PTFE. FEP tubing has little or no adhesion to other substances on the surface but can be specially treated to accept conventional industrial adhesives. can be specially treated to accept conventional industrial adhesives.

2. Electrical properties: FEP pipe has good electrical insulation properties. Its surface resistivity and volume resistivity are very high, 10^15 and 10^17 ohm-cm respectively. the dielectric strength of FEP tubing varies somewhat in different thicknesses, but usually meets the requirements. the dielectric constant of FEP tubing remains stable at different frequencies, making it suitable for a wide range of electrical applications.

Optical clarity: FEP tubing has good optical clarity and effectively transmits UV light. The specific UV transmittance depends on the quality and thickness of the tubing, but FEP tubing typically has good UV transmittance properties. In addition, FEP tubing has a refractive index of 1.341-1.347, which demonstrates good optical clarity.

FEP has the following major advantages over other materials:

What is the difference PTFE vs FEP ?

1. High Temperature Resistance: FEP pipe has a maximum service temperature of 200°C (392°F), while PTFE pipe has a maximum service temperature of 260°C (500°F). Therefore, PTFE tubing has a better ability to withstand high temperature environments.

2. Flexibility and durability: FEP tubing has good flexibility in the thin-walled portion of the tube, while PTFE tubing is relatively rigid.PTFE tubing has higher tensile strength and durability, and can withstand higher stresses and deformations.

3. non-stick properties: FEP pipe non-stick better, but PTFE pipe non-stick is more excellent. PTFE pipe surface almost does not adhere to other substances, with better prevention of adhesion and clogging.

Chemical resistance: PTFE pipe has better resistance to chemicals. It has good resistance to most chemicals, whereas FEP pipe may be affected under certain strong acid and alkali conditions.

HOW To Manufacturing Process OF FEP TUBING ?

fep making process

The extrusion process of polyfluoroethylene (FEP) pipe is as follows:

1. Raw material preparation: Mix the FEP resin powder with other additives according to a certain proportion and pre-dry to ensure the dryness of the raw material.

2. Melting: The pre-dried FEP resin powder is put into the feed port of the extruder, and melted into molten state by heating and mixing.

3. Extrusion: The molten FEP resin is pushed into the mold through the action of the screw and barrel of the extruder. In the mold, the FEP resin is formed into a tube.

4. Cooling: The extruded FEP tubing is rapidly cooled through a cooling unit to cure and stabilize the shape.

5. Cutting and collection: The cooled FEP tubes are cut into desired lengths and collected through a collection device.

6. Inspection and Packaging: The extruded FEP pipes are inspected for quality to ensure that they meet the specified standards and requirements. It is then packaged for transportation and storage.

The above is the typical extrusion process of FEP pipe, and there may be some slight differences and adjustments in the actual production to adapt to different production requirements and conditions
