PTFE is thin-walled transparent tubing, permitting simple visual evaluation of the components. It uses good abrasion resistance as a result of a low friction surface. PTFE also exhibits ultra-low gas permeability. Electric resistance is also high in PTFE, making it a popular selection for electrical insulators. PTFE is not prone to distortion, but can kink fairly easily. This is semi-rigid tubing so is not suitable for usage on peristaltic pumps. The material consists of no Substances of Very High Concern (SVHCs) as categorized by the REACH environmental law.
PTFE tubing is used in many industrial applications and in the last 10 years is been significantly used in medical devices. PTFE tubing has very low coefficient of friction, which suggests it has exceptionally smooth surface. This is good news for medical device application as this means PTFE tubing has surface which will not harbour neither aid in microbial development. It is essential to pick tubing of the correct material which performs under desired conditions, is commercially practical and available. PTFE tubing fits this costs. It’s a very versatile item certainly.
PTFE tubing is fitted to devices and machines using compression fittings such as connector and adapters. It is very important that the dimension resistance of ID & OD of the PTFE tubing be very tight so that there is no leak at the end fitting. The fittings are manufactured in numerous materials like stainless-steel qualities SS304 or SS316 and also using PTFE material. PTFE fitting are used with PTFE tubing in applications where metal fittings are not allowable. It’s important to note that leaks are credited to wrong cutting of the PTFE tubing prior to it is inserted in the fitting. Special cutters need to be used to make a perfect straight cut.
Tubes capricorn TL and Chemical Processing Industry have been using fluoropolymer tubing items from materials like PTFE and hose pipes for years for moving extremely caustic or harsh chemicals. More and more, PTFE tubing is replacing carbon and various other metal piping that weakens quickly. Now and for the future, PTFE will remain to offer the industry in crucial applications.
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 little as 0.3 mm to max 100 mmand wall thickness as small as 0.1 mm to 2 mm. PTFE tubing solution temperature is -60 to + 260-degree Celsius. PTFE tubing is popular as it is the most flexible in its class, because it has the very best chemical resistance in commercially available polymers and because it is non-stick (as a matter of fact it is just one of one of the most unsafe compounds known.
PTFE is superior tubing due to its outstanding chemical resistance and temperature strength. It is totally resistant to UV radiation. PTFE is regularly used in harsh atmospheres, such as for the sheathing of delicate equipment in marine setups. It remains reasonably flexible also at cryogenic temperature levels. This tubing has outstanding chemical and solvent resistance– it is almost inert and for that reason suits many research laboratory and non-contact medical applications (this is not medical grade tubing).
PTFE tubing is a corrosion-resistant tube that is used in many industrial applications. PTFE tubing is one of the only materials that will withstand specific kinds of acid. The tubing can be adjusted to operate in many scenarios. PTFE tubing is very low friction and can aid to improve flow. Often PTFE tubing is used in food service applications as well.
PTFE stands for Poly Tetra Fluoro Ethylene a polymer unintentionally discovered by Mr.Plunkett at Dupont. PTFE exists in primarily in powdered type and does not melt and flow. When warmed to temperatures above 350-degree Celsius PTFE changes from solid to gas stage. Because PTFE does not melt flow it is not possible to shot mould it. PTFE can nonetheless be compression moulded, ram extruded or paste extruded.
