PTFE Tubing is manufactured using paste extrusion. PTFE tubing manufactured using paste extrusion is flexible. It is possible to produce PTFE tubing with ID as little as 0.3 mm to max 100 mmand wall surface thickness as small as 0.1 mm to 2 mm. PTFE tubing service temperature is -60 to + 260-degree Celsius. PTFE tubing is popular as it is the most flexible in its course, because it has the best chemical resistance in commercially available polymers and because it is non-stick (as a matter of fact it is one of one of the most unsafe compounds known.
PTFE tubing is a corrosion-resistant tube that is used in many industrial applications. PTFE tubing is one of the only materials that will hold up against specific sorts of acid. The tubing can be adjusted to operate in many circumstances. PTFE tubing is very low friction and can aid to improve flow. Occasionally PTFE tubing is used in food solution applications as well.
PTFE stands for Poly Tetra Fluoro Ethylene a polymer mistakenly discovered by Mr.Plunkett at Dupont. Tubos Bowden PTFE exists in largely in powdered type and does not melt and flow. When warmed to temperatures above 350-degree Celsius PTFE modifications from strong to gas phase. Because PTFE does not melt flow it is not possible to injection molded it. PTFE can however be compression moulded, ram extruded or paste extruded.
PTFE is thin-walled translucent tubing, enabling simple aesthetic assessment of the contents. It uses good abrasion resistance as a result of a low friction surface. PTFE also exhibits ultra-low gas permeability. Electrical resistance is also high in PTFE, making it a popular selection for electric insulators. PTFE is not susceptible to distortion, however can kink fairly easily. This is semi-rigid tubing so is not suitable for usage on peristaltic pumps. The material contains no Substances of Very High Concern (SVHCs) as classified by the REACH environmental guideline.
PTFE tubing is used in many commercial applications and in the last 10 years is been significantly used in medical gadgets. PTFE tubing has very low coefficient of friction, which implies it has incredibly smooth surface. This is good news for medical device application as this suggests PTFE tubing has surface which will not harbour nor assist in microbial growth. It is essential to choose tubing of the proper material which executes under preferred conditions, is commercially practical and available. PTFE tubing fits this bill. It’s a very versatile item certainly.
PTFE is exceptional tubing as a result of its outstanding chemical resistance and temperature resilience. It is totally resistant to UV radiation. PTFE is often used in severe atmospheres, such as for the sheathing of delicate tools in marine setups. It continues to be moderately flexible even at cryogenic temperatures. This tubing has outstanding chemical and solvent resistance– it is virtually inert and therefore matches many lab and non-contact medical applications (this is not medical grade tubing).
The Steel Industry and Chemical Processing Industry have been using fluoropolymer tubing items from materials like PTFE and hose pipes for several years for moving extremely caustic or harsh chemicals. More and more, PTFE tubing is changing carbon and other steel piping that degrades rapidly. Now and for the future, PTFE will continue to serve the industry in crucial applications.
PTFE tubing is fitted to tools and machines using compression fittings such as adapter and adapters. It is important that the measurement tolerance of ID & OD of the PTFE tubing be very limited so that there is no leak at the end fitting. The fittings are manufactured in different materials like stainless steel grades SS304 or SS316 and also using PTFE material. PTFE fitting are used with PTFE tubing in applications where metal fittings are not permissible. It’s important to note that leakages are attributed to wrong cutting of the PTFE tubing before it is put in the fitting. Unique cutters need to be used to make a best straight cut.
