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.
Polytetrafluoroethylene (PTFE) is one of the most common materials used for seals. Expanded PTFE, or ePTFE, is a soft material with many of the same properties as PTFE. However, ePTFE is more flexible, making it a better choice for specific applications.
Both PTFE and Expanded PTFE have good chemical resistance. Additionally, Expanded PTFE has better creep resistance and cold flow. Some of the key characteristics of PTFE are as follows: It can perform well in environments with temperatures as high as 260 Degree Celsius.
