FEP Tube - Processing Techniques
1.Extrusion:
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.
4.laring:
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.
7.Printing and Labeling:
Information, identification, or branding can be printed or labeled onto the surface of FEP tubes for easy identification.
