Polyethylene tubing is commonly used in a wide range of industrial and consumer applications, including in the food and beverage, medical, and chemical industries. However, polyethylene tubing is not as temperature resistant as PTFE tubing and may not be suitable for certain applications that involve high temperatures.

PTFE is available in many different Grades as Virgin PTFE, Chemically Modified PTFE, Carbon Filled PTFE, Glass Filed PTFE, Carbon / Coke Filled PTFE, Graphite Filled PTFE, Bronze Filled PTFE, Bronze + Molybdenum Disulphide Filled PTFE, Aluminum Oxide Filled PTFE, Calcium Fluoride Filled PTFE, Stainless Steel Filled ...

Processing PTFE is difficult and expensive, and this is because of its rigid polymer chain structure.

Limitations of PTFE: Non-melt processable material. Low tensile yield strength and modulus (when compared to PEEK, PPS and LCP) High wear behaviour in unfilled state. Not weldable. Sensitivity to creep and abrasion. Low radiation resistance.

Teflon™ is a synthetic polymer, which is containing carbon and fluorine – this, therefore, makes it Polytetrafluoroethylene. YES, Teflon™ is a PTFE. Teflon™ is a trademarked name for PTFE, owned by Chemours.

The expanded PTFE sheet is made from 100 percent virgin PTFE and is exceptionally compressible. It is a food-safe product with great chemical resistance, making it a preferred sealing material in the food, beverage, and pharmaceutical sectors.
