Best Expanded PTFE Manufacturers - JD Jones

Why do we need a Head Gasket Sealer?

Polytetrafluoroethylene (PTFE) is a flexible, high-performance fluoropolymer made consisting of carbon and fluorine atoms that is widely utilized. It's made of low-friction materials and can withstand extreme temperatures. High density and flexibility are two features of PTFE. Because it is chemically non-reactive and insoluble, it is non-toxic. All of these qualities make PTFE appropriate for a wide range of applications, but strong loads can degrade it because of its considerable flexibility. Fillers can be added to PTFE to overcome this problem. JD Jones produces expanded PTFE in USA that is used widely in most industries. 

Let us understand the various advantages of Filled PTFE.

  1) Carbon with PTFE

It dissipates statically thanks to conductive carbon. Carbon's excellent heat conductivity also makes it a good choice for appliances that require it. It's not as corrosive as glass. It is available in two forms: powder and fiber. Carbon-filled PTFE has several advantages, including low permeability, increased wear resistance, and less deformation under heavy loads .Carbon increases PTFE's compressive strength, making it more wear resistant and decreasing deformation. Carbon is also conductive, making it ideal for applications requiring increased thermal conductivity.

2) Graphite with PTFE

Graphite gives PTFE a self-lubricating quality; it's commonly mixed with other fillers like glass or carbon. Carbon is static dissipative due to its electrical conductivity. Carbon's excellent thermal conductivity also makes it suitable for equipment that require it. It's not as corrosive as glass. It is available in two forms: powder and fiber. Reduced deformation under large loads, improved compressive strength, low permeability, and improved wear resistance are all advantages of carbon-filled PTFE. 

3) Bronze with PTFE

To diminish the chemical inertness and non-stick characteristics of PTFE, bronze is employed as a packing material. The wear resistance of PTFE is improved by adding bronze filler. These fillers are particularly beneficial in situations requiring high electrical and thermal conductivity. The bearings and piston rings are made of bronze, which accounts for 55% of the total.

4) Glass with PTFE

The most common filler in PTFE is glass. Glass fillers reinforce and extend the life of PTFE. The compressive strength of PTFE improves with the addition of glass filler. The porosity and creep propensity of glass-filled PTFE are reduced even more once it is sintered with inert gas. Hydraulic piston rings are made with it because of its great wear resistance. 

 5) Stainless Steel with PTFE

For applications involving steam and hot liquids at high temperatures, stainless steel packing should be used. With powdered stainless steel packing, polytetrafluoroethylene (PTFE) can bear greater loads. Food, beverage, and mechanical sectors can use this filler. Stainless steel filled PTFE works well in situations that are exposed to steam or hot liquids because it boosts wear and load resistance.

Expanded polytetrafluoroethylene (EPTFE) is one of the more innovative changes in PTFE processing and applications in recent years. EPTFE is used in the manufacture of lightweight, waterproof and breathable fabrics, microporous membranes, medical tubing and implants, microwave carriers, industrial sealants and high strength fabrics and cords.

Liantuo PTFE Sheet parts easy to process, affordable, durable. Parts made from this unique plastic are commonly used for mechanisms that are rotated or slid due to the low coefficient of friction and abrasion resistance of PTFE Sheet.

PTFE represents polytetrafluoroethylene, which is a fluorocarbon based polymer. Compared with other plastics, PTFE mechanical properties are low, can be -73 ° C to 204 ° C within a wide temperature range. Mechanical properties are usually enhanced by the addition of fillers. Typically, the filled PTFE retains its excellent chemical and high temperature properties while the filler improves mechanical strength, stability and abrasion resistance. It has excellent thermal and electrical insulation properties and low coefficient of friction.

PTFE is very dense and can not be processed by melting. PTFE must be compressed and sintered to form a useful shape. All standard equipment can be easily processed PTFE, including the most advanced CNC machining equipment. You can use standard mold cutting, drilling, milling and turning PTFE. Although occasional minor tolerances are required, they are usually not required. PTFE is very flexible, which allows the machined part to meet most of the work size.
