Description

What is PTFE?
 

Polytetrafluoroethylene PTFE Teflon, a strong, tough, waxy, nonflammable synthetic resin produced by the polymerization of tetrafluoroethylene. Known by such trademarks as Teflon, Fluon, Hostaflon, and Polyflon. PTFE is distinguished by its slippery surface, high melting point, and resistance to attack by almost all chemicals. These properties have made it familiar to consumers as the coating on nonstick cookware; it is also fabricated into industrial products, including bearings, pipe liners, and parts for valves and pumps.
 
 

Characteristics:

 
- Excellent chemical resistance
- Wide range of service temperature
- Excellent dielectric properties
- Non-stick, low friction
- No embrittlement or ageing
- Smooth surface finish can be achieved
- Non wetting
- Outstanding corrosion protection
- Electrical insulation
- High thermal stability and flame resistance
- Resistance to weathering
- Food grade compliancy

Processing methods:

 

 

PTFE Grades:

 
Virgin PTFE   
PTFE without a filler is one of the most chemically inert materials known and is used in many different applications and industries.
Glass Filled PTFE  
Virgin PTFE with 25% Glass fiber filler which dramatically increases compressive strength and lowers deformation under load.
Bronze Filled PTFE
The addition of Bronze to PTFE gives better dimensional stability and lowers creep, cold flow and wear.
Carbon Filled PTFE      
The addition of Carbon Fibre to PTFE increases the compressive strength and wear resistance. It provides good thermal conductivity and low permeability.
Stainless Steel Filled PTFE   
The material is extremely hard wearing, has excellent strength and stability under extreme loads and elevated temperatures whilst still retaining the low coefficient of friction of conventional PTFE.
 

Applications:

 
Petrochemical and chemical processing:
PTFE is the material of choice for gaskets, vessel linings, pump interiors, washers, rings, seals, spacers, dip tubes and well-drilling components because it is corrosion resistant and chemically inert;
 
Electrical applications:
PTFE is one of the best insulators known. In thin sections, it will insulate to 500 volts per mil. There are grades of PTFE which have even greater dielectric strength. PTFE can be machined into standoff insulators, and many different types of high voltage encapsulation devices for electrical components.
 
Semi-Conductor Industry:
PTFE is inert, and its operating temperature range is from - 170 °C to 280°C. When made to ultra-pure standards it is the material of choice for various items used in chip manufacturing, including encapsulation devices for quartz heaters, and the like.
 
Food, Beverage and Pharmaceutical industries:
Virgin PTFE is approved by the Food and Drug Administration for use in the food, beverage, cosmetics and pharmaceutical industries. Thin Film and sheets make an inert, no-toxic slide surface without microscopic depressions where microbes can grow. Conveyancing components - profiles, guide rails and slides - can withstand high temperatures inside baking and drying ovens and other heated segments of the food, cosmetics or pharmaceuticals manufacturing processes.
 
Laboratory applications:
PTFE piping, tubing and vessels are used in various laboratory ware because of their chemical resistance, and inertness. No contaminants adhere to the surface.
 
Bearing pads:
Glass filled PTFE can be cut or stamped into bearing pads, and will resist all weather-related degradation while remaining an inert interface between disparate construction materials, like steel and concrete.
