1. Basic Concepts

PTFE has excellent dielectric properties and provides excellent thermal insulation properties, and the operating temperature range is -400°F to 500°F. PTFE is the most chemically resistant plastic known and is not affected by most corrosive liquids, vapours and gases. PTFE is usually offered in thicknesses ranging from .002″ to .250″ and meets FDA and AMS specifications, making it acceptable for the medical and food production industries.
In a strong chemical environment, contamination of the medium is not allowed, and the use of standard gaskets is very complicated. Here PTFE gasket is used as a flange gasket connection. For example, in the (petro) chemical industry, in the process industry. The PTFE gasket is also very suitable for applications in the food industry. PTFE is physiologically inactive and can be used in direct contact with food.
Weiten supplies expanded PTFE gasket, modified PTFE gasket, PTFE bonded EPDM gasket, pure PTFE gasket.

2.Advantages of PTFE Gasket

Exceptional corrosion resistance: Withstands almost all chemical media (except molten alkali metals) and a pH range of 0–14, making it ideal for handling corrosive substances such as strong acids and alkalis.

Wide temperature range: Suitable for long-term use between -100°C and +100°C; modified materials offer an even broader temperature range.

Clean and aging-resistant: High-purity, non-contaminating, and non-stick material suitable for the food and pharmaceutical industries; highly resistant to aging, ensuring a long service life.

Easy to process: Can be readily machined (turning) or molded into various sizes, facilitating non-standard customization.

3.Key Application Areas of PTFE Gasket

Thanks to their unique properties, PTFE gaskets are widely used for sealing connections in various industrial sectors, including pumps, valves, pipelines, and reactors.

Chemical Industry: Used to seal against strong acids, strong alkalis, and various organic solvents, preventing leakage.

Food and Pharmaceutical Industries: Suitable for sanitary-grade piping and equipment due to their clean, non-contaminating nature.

Oil and Gas: Used for sealing pipeline flanges that transport corrosive media.

Electronics Industry: Used in piping systems with strict purity requirements, such as those handling ultrapure water or chemical reagents.

General Machinery: Used for shaft seals and static sealing applications in equipment such as compressors, mixing vessels, and centrifuges.
