PTFE WASHER

Product Description

PTFE (polytetrafluoroethylene) washers are components used in various applications where resistance to chemicals, high temperatures, and low friction are required. Here are short specifications of PTFE washers:

1. Material: Made from PTFE (polytetrafluoroethylene), a synthetic fluoropolymer known for its exceptional chemical resistance, low friction coefficient, and high-temperature tolerance.

2. Features:

   - Chemical Resistance: Resistant to a wide range of chemicals, including acids, bases, solvents, and fuels.

   - Temperature Resistance: Can withstand temperatures ranging from -200C to +260C (-328F to +500F), making them suitable for both cryogenic and high-temperature applications.

   - Low Friction: Exhibits a low coefficient of friction, reducing wear and ensuring smooth operation in moving parts.

   - Non-Stick Properties: Non-adhesive surface prevents materials from sticking to the washer, facilitating easy cleaning and maintenance.

   - Electrical Insulation: Provides excellent electrical insulation properties, making them suitable for electrical applications.

3. Applications: 

   - PTFE washers find applications in various industries, including aerospace, automotive, chemical processing, food and beverage, pharmaceuticals, and electronics.

   - Common applications include sealing, insulating, spacing, and reducing friction in assemblies where chemical resistance and temperature stability are crucial.

4. Sizes and Shapes: 

   - Available in a wide range of sizes and shapes, including flat washers, gaskets, spacers, and custom-designed configurations to suit specific application requirements.

5. Installation:

   - Can be easily installed by placing them between mating surfaces or components to provide sealing, insulation, or spacing functions.

   - Typically used in conjunction with bolts, screws, or other fasteners to distribute load and prevent leakage.

Overall, PTFE washers offer excellent chemical resistance, temperature stability, low friction, and electrical insulation properties, making them versatile components in various industrial applications where reliability and performance are paramount.
