The Steel Industry and Chemical Processing Industry have been using fluoropolymer tubing products from materials like PTFE and pipes for several years for moving very caustic or harsh chemicals. Increasingly more, PTFE tubing is replacing carbon and various other metal piping that degrades rapidly. Currently and for the future, PTFE will remain to serve the industry in essential applications.
PTFE tubing is used in many commercial applications and in the last 10 years is been increasingly used in medical tools. PTFE tubing has very low coefficient of friction, which means it has extremely smooth surface. This is good information for medical tool application as this indicates PTFE tubing has surface which will not harbour nor assist in microbial development. It is necessary to select tubing of the correct material which executes under preferred conditions, is commercially feasible and available. PTFE tubing fits this expense. It’s a very versatile product undoubtedly.
PTFE is thin-walled translucent tubing, permitting simple visual evaluation of the components. It supplies good abrasion resistance due to a low friction surface. PTFE also shows ultra-low gas permeability. Electrical resistance is also high in PTFE, making it a popular option for electric insulators. PTFE is not prone to distortion, yet can kink relatively quickly. This is semi-rigid tubing so is not suitable for use on peristaltic pumps. The material has no Substances of Very High Concern (SVHCs) as identified by the REACH environmental guideline.
PTFE tubing is a corrosion-resistant tube that is used in many commercial applications. PTFE tubing is one of the only materials that will withstand particular types of acid. The tubing can be adapted to operate in many scenarios. PTFE tubing is very low friction and can help to improve flow. Sometimes PTFE tubing is used in food solution applications as well.
PTFE tubing is fitted to tools and machines using compression fittings such as connector and adapters. It is very important that the measurement resistance of ID & OD of the PTFE tubing be very tight to ensure that there is no leak at the end fitting. The fittings are manufactured in various 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 acceptable. It’s important to keep in mind that leakages are attributed to incorrect cutting of the PTFE tubing prior to it is inserted in the fitting. Special cutters require to be used to make an ideal straight cut.
Tubos Bowden PTFE is premium tubing as a result of its outstanding chemical resistance and temperature strength. It is absolutely resistant to UV radiation. PTFE is often used in severe atmospheres, such as for the sheathing of delicate devices in aquatic settings. It stays moderately flexible also at cryogenic temperatures. This tubing has outstanding chemical and solvent resistance– it is nearly inert and for that reason fits many lab and non-contact medical applications (this is not medical quality tubing).
PTFE Tubing is manufactured using paste extrusion. PTFE tubing manufactured using paste extrusion is flexible. It is possible to make PTFE tubing with ID as tiny as 0.3 mm to max 100 mmand wall surface thickness as little as 0.1 mm to 2 mm. PTFE tubing solution temperature is -60 to + 260-degree Celsius. PTFE tubing is popular as it is one of the most flexible in its class, because it has the best chemical resistance in commercially available polymers and because it is non-stick (in fact it is just one of one of the most slippery compounds recognized.
PTFE stands for Poly Tetra Fluoro Ethylene a polymer mistakenly found by Mr.Plunkett at Dupont. PTFE exists in mainly in powdered form and does not melt and flow. When warmed to temperatures above 350-degree Celsius PTFE adjustments from solid to gas phase. Because PTFE does not melt flow it is not possible to injection mould it. PTFE can nonetheless be compression molded, ram extruded or paste extruded.
