The main property of PTFE is that it is practically inert, it does not react with other chemical substances except in very special situations. This is basically due to the protection of the fluorine atoms on the carbon chain. It has a very low coefficient of friction and great impermeability, also maintaining its qualities in humid environments. It is also a great electrical insulator and extremely flexible, it is not altered by the action of light and is able to withstand temperatures from -270 °C (3 K) to 270 °C (543 K). Its most well-known quality is its non-stick property.

15% Glass Fiber filled PTFE provides excellent mechanical, thermal, chemical, and electrical properties, high wear and friction resistance, and a low coefficient of friction.

Properties:Improved wear resistance. Improved chemical resistance (except for alkalis and hydrofluoric acid).

Aplications:Valve seats, seals, and bearings require resistance to sliding and chemicals.

PTFE Loaded with 25% by weight Fiberglass increases compressive strength, stiffness, and wear resistance, reduces cold flow and creep. It has a minimal effect on chemical and electrical properties. Gaskets made from this material will not swell due to moisture absorption and can easily withstand daily wear.

Aplications: Valve seats, gaskets, roller covers, shaft bearings, filter housings, sliding rails, chemical engineering, machinery parts, transportation and conveyance technology, pump construction and instruments, electrical industry, electronics, laser technology, smoke purification, pure water production, filter technology, food and medical technology.

PTFE Loaded with 50% Bronze and 7.5% Fiberglass by weight is often used with 50% bronze particles by weight to increase its creep resistance and is easy to machine. Fiberglass resists well to acid and oxidation but is susceptible to attack by bases. It provides parts with excellent wear resistance, reduced friction, and high heat conductivity.

PTFE loaded with 15% fiberglass and 5% molybdenum disulfide by weight.

Properties: Excellent chemical stability Improved thermal conductivity and coefficient of friction. Enhanced compression and wear resistance. Self-lubricating properties, particularly at start-up.

Aplications: Dynamic sealing applications with rotary and reciprocating motion. Pneumatic applications. Mechanical applications.

Carbon is one of the best compounds for chemical use. It has high thermal conductivity and high wear and pressure resistance. It has less deformation under heavy loads and better wear resistance than virgin PTFE. Because carbon is conductive, it is suitable for applications that require higher thermal conductivity than PTFE alone, and it also becomes a static dissipator due to its electrical conductivity. Carbon can be added in the form of carbon powder or carbon fiber. It can be abrasive, but not to the same extent as glass.

Applications: Recommended for piston rings and other dynamic seals.

The Ekonol® aromatic polyester fillers are a key component in extending the lifespan of parts and components made from PTFE compounds. The exceptional properties of PTFE fillers with Ekonol provide maximum wear resistance, dimensional stability, and corrosion resistance. The highly crystalline Ekonol polymer produces unparalleled thermal stability along with good creep resistance and excellent load-carrying capability. These features make Ekonol polyester PTFE fillers the ideal filler for PTFE compounds to increase the lifespan of bearings, seals, rotors, and related parts. While glass compounds can be abrasive, the round shapes of Ekonol particles will not score soft metal surfaces. Additionally, Ekonol/PTFE blends exhibit better inherent wear resistance than other PTFE compositions, with good lubricity in molded parts.

Carbon itself is a brittle material with poor wear and mechanical strength properties. However, with the two combined formulations of carbon-filled PTFE, the resulting material has excellent mechanical and wear properties, retains the excellent friction properties, and is an excellent choice for seals and rings in dynamic and high-pressure applications. Carbon-filled PTFE also provides good thermal conductivity, low permeability, and is also electrically conductive, making it a good choice for anti-static applications..

PTFE Loaded with 15% Graphite by weight, has a low coefficient of friction compared to other loaded PTFE materials. It has a higher flexural modulus and surface hardness than virgin PTFE.

Applications: Bearings Anti-static applications Wear pads Piston rings.

PTFE Loaded with 10% by weight of PEEK (Polyetheretherketone) has similar properties as PTFE loaded with Ekonol, although this material has FDA and CE certifications for use in the food industry. It is resistant to almost all chemicals but is not resistant to halogens, elemental fluorine, CF3, and molten alkali metals.

PTFE 50% Inox is a preferred compound for parts and components that require very good mechanical properties, offering an excellent combination of typical properties of PTFE fluoropolymer resins. It provides excellent resistance to continuous service temperatures - working conditions from -100°C up to 250°C, and for limited periods, even at higher temperatures. The product's resistance to low temperatures allows for satisfactory performance of up to -200°C. PTFE 50% Inox offers high inertness towards nearly all known chemicals, with only elemental alkali metals, chlorine, and elemental fluorine at high temperatures and pressures affecting its properties. It provides insoluble properties in all solvents up to temperatures of up to 300°C.
