PTFE ( Polytetrafluoroethylene PTFE Products ) |
PTFE -an acronym for Polytetrafluoroethylene - is a high molecular weight polymer, one of the most versatile plastic materials known and useful for a large range of products for applications excluded to other materials. Commonly referred to as Teflon PTFE has extremely low coefficient of friction Main properties of our range of PTFE sheet, rod and tube are:
|
- High heat resistance
- High resistance to chemical agents and solvents
- High anti adhesiveness
- High dielectric properties
- Low friction coefficient
- Non-toxicity.
PTFE is generally considered a thermoplastic polymer; at 327°C it maintains a very high viscosity, thus requiring particular transformation techniques for manufacturing of finished and semi-finished goods. PTFE can be employed at any temperature from -200°C to +260°C For more detailed technical information for PTFE click here Choose material grade
Virgin PTFE
This virgin grade PTFE, and its advanced properties make it an ideal choice of material for a wide range of applications - particularly those requiring high temperature, chemical resistance and excellent slip-stick performance
Available colours: White
Available to buy in: Sheet: 0.25mm to 80mm thick Rod: 4mm to 300mm diameter Tube: various OD x ID diameters |
25% Glass Filled PTFE
PTFE is reinforced with 25% glass fibres. The added glass fibre improves the wear properties and, to a minor degree, also the deformation strength under load while leaving substantially unchanged the electrical and chemical characteristics. However, it is important to remember that glass, has a rather poor resistance against alkalis and is easily attacked by hydrofluoric acid. The coefficient of friction is also slightly increased. Available colours: Off-White
Available to buy in: Sheet: 1.5mm to 60mm thick Rod: 6mm to 200mm diameter Tube: limited range of OD x ID diameters |
25% Carbon Filled PTFE
25% carbon is added to the PTFE, along with a small percentage of graphite. The carbon tends to improve - to a considerable degree - wear and deformation strength, whilst leaving the chemical resistance practically unchanged, substantially modifying the electrical properties
Available colour: Black
Available to buy in: sheet, rod and tube |
Other Filled PTFE
Grades PTFE, because of the properties previously described, is used in many applications. Properties can be improved and/or modified by adding suitable fillers. The fillers most commonly used are: glass fibre, carbon, bronze or graphite, in
form of powder intimately mixed with the PTFE; other fillers are: molybdenum bisulphide, metal powders, ceramics, metal oxides and mixtures of two or more additives. Available colour: a ccording to filler Available to buy in: sheet, rod and tube |
