Expanded PTFE Tapes

Description

Expanded PTFE sheet is an extremely compressible material manufactured from 100% virgin PTFE. It is a food approved product and has excellent resistance to a wide range of chemicals, making it a popular sealing material in the food, drink and pharmaceutical industries.

Expanded Polytetrafluoroethylene (ePTFE) is a flexible, mesh-structured resin made from PTFE that has many industrial applications:

• Uses

ePTFE is used in medical devices, food processing, oil and gas, and other industries that require tight seals. It’s also used in electronic insulators and high performance filters.

• Properties

ePTFE is non-toxic, hygienic, and chemically inert, like PTFE. It’s also softer and more flexible than regular PTFE gaskets, so it can conform to irregular surfaces. ePTFE is permeable to air, gases, and water vapor, but it still resists particulates and liquids.

• Manufacturing

ePTFE is made by stretching PTFE resin through a unique processing method. The manufacturing process includes:

Expanded PTFE (ePTFE) has many properties, including:

• Chemical resistance: ePTFE is chemically resistant and inert, and can withstand a wide range of pH levels.
• Non-toxic: ePTFE is non-toxic and hygienic.
• Electrical insulation: ePTFE has excellent electrical insulation properties.
• Low creep relaxation: ePTFE maintains its sealing integrity over time, even under continuous compression.
• Non-stick: ePTFE has non-stick properties that prevent contaminants from adhering to the surface.
• Permeable: ePTFE is permeable to air, gases, and water vapor, while still resisting particulates and liquids.
• Soft and flexible: ePTFE is softer and more flexible than regular PTFE gaskets, so it can conform to irregular surfaces.
• Easy to compress: ePTFE is easier to compress than regular PTFE gaskets.
• FDA approved: ePTFE gasket material often complies with FDA regulations for food-contact applications.
• Compatible with many flange materials: ePTFE gasket material is compatible with a wide range of flange materials
