Polytetrafluoroethylene (PTFE) sheet, also known as TeflonTM, is a high-performance engineering plastic. It has a wide operating temperature range, is chemically inert (except for some alkali metals), and has a very low coefficient of friction. PTFE has excellent dielectric properties and corrosion resistance, but it is prone to creep due to its non-stick surface.
Group provides a variety of grades with varying characteristics. Our most common and standard grade of PTFE plastic is Virgin, which meets FDA and EC food contact regulations. It can supply this grade with an etched backing that allows the material to be bonded to other materials, or it can be supplied with a dimpled surface if needed. Carbon, glass, stainless steel, and bronze-filled composites are available and offer improved dimensional stability and creep resistance and other individual benefits such as static dissipation and thermal conductivity. In addition, we can provide detectable metal options for use in food processing applications and skived PTFE if an adhesive backing is required.
PTFE is frequently used to make gaskets and seals, insulators, slide bearings, plates, and linings. Because of the material’s properties, the PTFE sheet is machined into a wide variety of finished products for use in aerospace, chemical, printing and publishing, power generation, and food and pharmaceutical. Although PTFE is simple to machine, it is difficult to bond (unless supplied with a chemically etched backing). Due to its soft surface, it is not suitable for applications involving highly abrasive materials.
We provide a plastic machining service that uses cutting-edge CNC technology and can produce parts ranging from simple to complex shapes if needed. There is also a PTFE rod and tube available. Please see the links below or click the ‘buy online’ button above for more knowledge on each grade.
Standard Grades of PTFE Sheet
PTFE Sheet – Virgin
Our standard and most popular grade; virgin PTFE offers exceptional resistance to chemicals and has a very low co-efficient of friction. It complies with EC and FDA regulations and offers good dielectric strength. Temperature range -200°C up to +260°C.
PTFE Sheet – Blue Food Quality
Commonly used in food processing applications due to its highly visible colour, blue food quality PTFE sheet retains the key characteristics of the virgin alternative. It also complies with FDA and EC regulations. Temperature range -200°C up to +260°C.
PTFE Sheet – Carbon Filled
Provides improved dimensional stability and resistance to creep and wear compared to virgin PTFE. Carbon filled PTFE is partially electrically conductive and is used to help dissipate electric charge. Temperature range -200°C up to +260°C.
PTFE Sheet – Glass Filled
Glass filled PTFE sheet offers improved dimensional stability and resistance to creep when compared to virgin PTFE. It is commonly manufactured into bearings that work at low pressure / velocity (PV) values. It is not suitable for food contact applications. Temperature range -260°C up to +250°C.
PTFE Sheet – Stainless Steel Filled
Providing enhanced mechanical properties, resistance to wear and improved thermal conductivity compared to the Virgin alternative. Stainless steel PTFE is FDA approved and is commonly manufactured into slide runners and pads. Temperature range -200°C up to +260°C.
PTFE Sheet – Bronze Filled
Bronze filled PTFE sheet provides improved mechanical strength, thermal conductivity and resistance to cold creep when compared to standard grades of PTFE. It is commonly used in dynamic applications that require a strong, hard material. Temperature range -200°C up to +260°C.
PTFE Sheet – Metal Detectable
Offers outstanding resistance to corrosion, chemicals and temperature. Metal detectable PTFE contains additives that are visible to most metal detector scanning equipment. It is EC and FDA approved for food contact applications. Temperature range -200°C up to +260°C.
PTFE Sheet – Skived
Manufactured from a thin film of PTFE with a self-adhesive silicone backing. Skived PTFE has a non-stick surface that is chemically inert and provides resistance to high temperatures. It is used in applications where an instant anti-stick lining is required. Temperature range -73°C up to +260°C.
