Expanded PTFE Joint Sealant is made from 100% white pure virgin imported PTFE resin combined with a continuous self-adhesive strip for easy application.
Expanded PTFE Valve Stem Packing is made from 100% white pure virgin PTFE resin. It is a white, soft and round product. In possession of the characteristics of high tensile strength, self-lubrication, low coefficient of friction and corrosion resistance, it can be widely used in valves, faucet stems, rotating shafts, reciprocating plungers, stuffing boxes and flanges etc.
Expanded PTFE spiral wound gasket filler material is made from 100% white pure virgin PTFE resin. It is unique tape, will not age, harden, shrink or dry out in service, unaffected by common chemicals.With good sealability and flexibility, it can seal rough or damaged surface.it is widely used in spiral wound gasket.
Expanded PTFE yarn is made from 100% white pure virgin PTFE resin. It is flat type,without lubricants,through expanded Process, high tensile strength.it is an ideal raw material for ePTFE braided packing or other braided packing combination.
Expanded PTFE Gasket is 100% PTFE, resistant to all corrosive media. Soft, twistable and bendable at will. Excellent anti-wriggle variation ability and cold current resistance, even in case of cross change of temperature and pressure, good sealing can be assured.
The expanded PTFE sheet is made from 100 percent virgin PTFE and is exceptionally compressible. It is a food-safe product with great chemical resistance, making it a preferred sealing material in the food, beverage, and pharmaceutical sectors.
Limitations of PTFE:
Non-melt processable material.
Low tensile yield strength and modulus (when compared to PEEK, PPS and LCP)
High wear behaviour in unfilled state.
Not weldable.
Sensitivity to creep and abrasion.
Low radiation resistance.
(a) Preforming to compress the compound of PTFE fine powder and lubricant and remove the air in the compound. (b) Paste extrusion to make a rod by the press extruder machine from the preform. (c) Calendaring to make a primary tape from the rod by a twin-roller.
Polyethylene tubing is commonly used in a wide range of industrial and consumer applications, including in the food and beverage, medical, and chemical industries. However, polyethylene tubing is not as temperature resistant as PTFE tubing and may not be suitable for certain applications that involve high temperatures.
Ceramic-coated pans have a non-stick surface that is free from PFOA and PTFE, the potentially harmful chemicals found in Teflon. They are generally considered safe and provide good non-stick properties. However, the durability of the ceramic coating can vary, and it may wear off over time.
In this example, when the part is heated from 77°F/25°C to 392°F/200°C, at the upper end of the temperature range the PTFE component will grow approximately 24 mm longer than the mating metal part.
