PTFE Plastic Sheet

PTFE Plastic Sheets – Polytetrafluoroethylene (Teflon)

Advanced Seals & Gaskets Ltd (ASG) supply a wide range of plastic sheets, including high-performance PTFE sheets, also known as Polytetrafluoroethylene or Teflon. PTFE is a versatile, fluorocarbon-based polymer widely used across industries due to its exceptional chemical resistance, high thermal stability, low friction, and excellent electrical insulation properties.

Our PTFE sheets are available in a range of thicknesses from 0.25mm to 100mm and sheet sizes up to 1500mm x 1500mm, depending on thickness. We offer PTFE in sheets, rolls, or tube form, which can be precisely cut, machined, or converted in-house into finished components such as washers, pads, strips, gaskets, or bespoke parts.

    What Are PTFE Plastic Sheets?

    PTFE sheets are made from Polytetrafluoroethylene, a fluorocarbon material composed entirely of carbon and fluorine. This molecular structure gives PTFE unique properties:

    • Hydrophobic: PTFE repels water, preventing moisture absorption.

    • Non-stick: Materials do not adhere to PTFE, making it ideal for food contact surfaces or chemical processing.

    • Chemically inert: Resistant to most chemicals, acids, alkalis, and solvents.

    • Low friction: Reduces wear, energy consumption, and heat buildup in moving components.

    • High dielectric strength: Excellent for electrical insulation applications.

    While naturally white, PTFE sheets can also be supplied in custom colours to suit aesthetic or functional requirements. Virgin PTFE has excellent chemical resistance but moderate mechanical strength, which can be enhanced with fillers like glass fiber or carbon, increasing durability and load-bearing capacity.

    Why Use PTFE Plastic Sheets?

    PTFE sheets are used in high-performance applications due to their unique properties:

    1. High Temperature Resistance: PTFE maintains stability in temperatures ranging from -200°C to +260°C, with short-term resistance up to 300°C, making it suitable for industrial ovens, chemical reactors, and heat shields.

    2. Chemical Inertness: PTFE is resistant to corrosive chemicals, solvents, and cleaning agents, protecting machinery, pipelines, and components from chemical degradation.

    3. Low Friction & Non-stick Surface: Ideal for applications where parts slide against each other, PTFE reduces wear, energy consumption, and noise, extending equipment life.

    4. Electrical Insulation: PTFE’s dielectric properties make it ideal for circuit boards, electrical components, and insulators, safely protecting devices from current leakage.

    5. Food & Pharmaceutical Safe: FDA-compliant grades of PTFE are perfect for contact with food, beverages, or pharmaceuticals, preventing contamination while remaining easy to clean.

    Advantages of PTFE Plastic Sheets

    Using PTFE sheets offers numerous industrial and commercial advantages, including:

    • Durability: Resistant to wear, corrosion, and UV degradation.

    • Wide Temperature Range: Performs under extreme heat and cold.

    • Chemical Resistance: Withstands acids, alkalis, and most solvents.

    • Non-toxic & FDA Compliant: Safe for food, drink, and pharmaceutical applications.

    • Flame Resistance: UL94 V-0 rated, self-extinguishing.

    • Low Friction & Non-stick: Reduces component wear and prevents sticking of materials.

    • Electrical Insulation: Ideal for high-voltage and precision electrical applications.

    Conversion and Custom PTFE Components

    At Advanced Seals & Gaskets Ltd, our in-house facilities allow us to convert PTFE sheets into bespoke components:

    • Pads & Washers: Cut to precise thickness and diameter for industrial or mechanical applications.

    • Strips & Gaskets: Custom shapes and sizes for sealing, vibration reduction, and component protection.

    • Laminated Components: PTFE sheets can be laminated with foils, adhesives, or other materials for enhanced properties.

    We use advanced saws, presses, and oscillating knives to ensure precision, guaranteeing components meet exact customer specifications.

    Applications of PTFE Plastic Sheets

    PTFE sheets are widely used across industries due to their versatility, durability, and chemical resistance:

    • Chemical Industry: Lining tanks, seals, and gaskets for corrosive chemicals.

    • Food & Beverage: Non-stick surfaces, conveyor parts, and FDA-compliant packaging.

    • Pharmaceutical Industry: Clean, inert surfaces for processing medicines and supplements.

    • Electrical & Electronics: Insulation sheets, spacers, and circuit components.

    • Industrial Machinery: Bearings, wear pads, slides, and machine guides.

    • Laboratories: Containers, tubing, and fittings handling corrosive materials.

    PTFE is particularly valued in high-temperature, high-wear, or chemically aggressive environments, providing a long-lasting solution where other plastics fail.
