Polytetrafluoroethylene, aswell accepted as the PTFE, was advised for use and appliance in selected areas and fields area other abstracts could not bear adorable performance. Since its analysis in 1950s new applications are getting apparent for PTFE and the list keeps growing. A attenuate aggregate of some different backdrop fabricated the actual so approved afterwards and popular.
Going by the present scenario, you can come across a variety of PTFE products in the market, including tubes, rods and sheets. It has turned out to be a material with many commercial applications in the industrial, medical and consumer markets where this material is sometimes used in unconventional ways. Teflon products are preferred, the PTFE tubes are particularly significant. Let us take a glance at the prominent applications of the tubes along with what make them suitable for the respective usages.
Teflon PTFE manufactured from the same polymers which are used to develop tubes for plastic extrusion. The process of tube development involves the appropriate mixture of resin which makes these tubes suitable to operate at varying temperature up to 500°F.
The best thing about PTFE is its heat shrink property, which makes it different from other tubes which makes it suitable for protecting wires and cables in various industries and their applications. Appreciating features of heat shrink-able PTFE tubing are like non-sticky nature, flexibility of working under different temperatures, reducing friction and chemical resistance.
High- Temperature Resistance
To begin with, PTFE is resistance to heat is one of the highest among plastics. The tubes remain unaffected by very high or extremely low temperatures. The Teflon tubes are comfortable working within a temperature range of -260 -70 degree C to +260 degree C. With an extraordinary high melting point of 327 degree C, a tube of average size can transfer fluids at very high temperatures. Insulation of metal parts is also facilitated, which is why, it is of considerable use in the automotive industry.
Polytetrafluoroethylene has always been a very useful part of the electrical industry and this largely attributable to its dielectric strength. Teflon tubes are widely used in the insulation of electrical cables by virtue of their potential to operate under a range of 50-120 kilo volts per mm.
Lowest Co-Efficient of Friction
PTFE has a very low- coefficient of friction with practically identical dynamic and static coefficient. This property is found in not just in the tubes or rods but also the sheets that are gradually becoming popular. A 0.1 coefficient of friction of the tubes has brought them into use in the field of medicine. Interestingly enough, Teflon is used in manufacturing catheters and snares.
Strong Chemical Resistance
Last but not the least; PTFE tubing is exceptionally suitable for a number of purposes in the chemical industry. The material is resistant to all kinds of corrosion and amazing water repellent properties. PTFE does not absorb water. Except a few materials like molten alkali metals, fluorine and chlorine trifluoride, it remains unaffected by all other types of chemicals. Transferring of chemical substances and protection of metal parts becomes easy due to this feature.
