PTFE Properties

PTFE, also known under the brand name Teflon, has the lowest coefficient of friction of any known solid material and melts between 260°C and 327°C. It’s fairly hard and fairly stiff too, so it’s ideal for parts including things low friction bushings to main assembly parts. Thermoplastics often swell just before they melt, so PTFE […]

PCTFE Differences from PTFE

PCTFE has high tensile strength and good thermal characteristics. It is nonflammable and the heat resistance is up to 175 °C.It has a low coefficient of thermal expansion. The glass transition temperature (Tg) is around 45 °C. PCTFE has one of the highest limiting oxygen index.It has good chemical resistance. It also exhibits properties like […]


PTFE Etching

Etching is a chemical process that removes the fluorine atoms from the surface layer of the fluoropolymer. This surface layer is so thin; it is most conveniently measured in Angstroms. Once the fluorine atoms are removed, the carbon atoms left behind in the etched polymer quickly forms temporary bonds with atoms from the air, such […]

PTFE Properties

PTFE resin is in a class of paraffinic polymers that have some or all of the hydrogen replaced by fluoride. The original PTFE resin was invented by DuPont in 1938 and called Teflon®. PTFE is a crystalline polymer with a melting point of about 621° F (327° C). Density is 2.13 to 2.19 gm/cc. PTFE […]

Nylon membranes

What are the differences between Nylon and PTFE filters?

Nylon membranes for filtration using syringe filter devices and which membrane can be used with different solutions and or sovlents. PTFE as a membrane for syringe filters is considered to be more “chemically resistant” and Nylon to be the most “extractable free” for HPLC or dissolution testing. The simple explanation of the differences is that […]


PTFE Materials & Porous PTFE Plastic Polymer

Polytetrafluoroethylene (PTFE) is a versatile polymer used in a broad range of medical, industrial, and high technology applications. Porous PTFE is inert, making it unreactive to most chemicals, and, it can work in high processing and operating temperature environments (500°F / 260°C continuous). Porex porous PTFE offers excellent thermal, electrical, mechanical, and chemical properties as […]


The physical properties of PTFE

Polytetrafluoroethylene (PTFE) is very non-reactive and is often used in containers holding reactive and corrosive chemicals. According to DuPont, its melting point is 600 K (327 °C; 620 °F). It maintains high strength, toughness and self-lubrication at low temperatures down to 5 K (-268.15 °C; -450.67 °F), and good flexibility at temperatures above 194 K […]


PVC & PTFE Material Comparison

Polytetrafluoroethylene (PTFE) is a synthetic material accidentally invented in the late 1930s while a chemist was endeavoring to develop a new type of perfluorethylene-based refrigerant. Rather than achieving a chlorofluorocarbon, the scientist was surprised to find that the perfluorethylene used in the process reacted with the iron content of its container and polymerized under pressure. […]


Properties of PTFE and Some Other Insulating Materials

PTFE (Polytetrafluoroethylene) Teflon ® The combination of chemical and physical properties of PTFE is a consequence of its true fluorocarbon structure. This unusual structure leads to a material which has an almost universal chemical inertness; complete insolubility in all known solvents below 300°C; excellent thermal stability; and unsurpassed electrical properties, including low dielectric loss, low […]
