PTFE

PTFE (Polytetrafluoroethylene) sheets, often referred to as Teflon sheets, are known for their exceptional chemical resistance, low friction and high thermal stability. They are used in various applications, especially where exposure to chemicals or high temperatures is of a concern. PTFE sheets are also known for their non-stick surface and excellent insulation properties.

Key properties of PTFE

• PTFE is resistant to almost all chemicals, making it suitable for use in harsh chemical environments.
• PTFE has a very low coefficient of friction, making it ideal for applications requiring low friction and wear resistance.
• PTFE can withstand a wide range of temperatures, from very low (-240°C) to high (260°C).
• PTFE’s smooth non stick surface is beneficial in various applications including food processing.
• PTFE has excellent electrical insulation properties.

Applications

• Chemical industry – gaskets, seals, linings for pipes and tanks.
• Food industry – non-stick surfaces for cooking equipment and packaging.
• Electrical industry – insulation and circuit boards.
• Sliding applications – bearings, seals and wear-pads.
• Aerospace due to its thermal stability and chemical resistance.
