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.
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.
PTFE Porous Membrane is made from 100% virgin PTFE with biaxially oriented.Due to special microporous structure,it have high breathability,high tensile strength.In possession of the characteristics of chemical corrosion resistance,food grade,aging resistance,high water pressure resistance, High particle interception rate,frame proof,not sticky,it is widely used in incineration,clothing,cement,medical,chemical industrial fields and so on.
Expanded PTFE Sheet is made from 100% virgin PTFE with biaxially oriented,and more strength than ptfe joint sealant. it is white color，peak temperature 310℃，In possession of the characteristics of self-lubrication, low coefficient of friction and widely chemical corrosion resistance with good resistance of pressing, cold flow,and creep relaxation.
Expanded PTFE Joint Sealant is made from 100% white pure virgin imported PTFE resin combined with a continuous self-adhesive strip for easy application.
(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.
Teflon™ is a synthetic polymer, which is containing carbon and fluorine – this, therefore, makes it Polytetrafluoroethylene. YES, Teflon™ is a PTFE. Teflon™ is a trademarked name for PTFE, owned by Chemours.
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.
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.
Both PTFE and Expanded PTFE have good chemical resistance. Additionally, Expanded PTFE has better creep resistance and cold flow. Some of the key characteristics of PTFE are as follows: It can perform well in environments with temperatures as high as 260 Degree Celsius.
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.
