FEP Tube - Processing Techniques 


FEP resin is heated and forced through a die to form the desired tube shape. This is a common method for producing FEP tubes of various sizes.

2.Heat Shrink Tubing: 

FEP heat shrink tubing is heated to shrink down and conform to the shape of the object it's covering, providing insulation, protection, or sealing.

3.Coiling and Bending: 

FEP tubes can be coiled or bent to achieve specific shapes or routing in applications where flexibility is required.


The end of a FEP tube can be flared to facilitate connections with other components, such as fittings or connectors.

5.Cutting and Welding: 

FEP tubes can be cut to specific lengths and welded together to create complex structures or longer tubing runs.

6.Lining and Coating: 

FEP can be used to line or coat other materials, providing a protective barrier against corrosion or chemical attack.
