Dgflon Ptfe Tube
Polytetrafluoroethylene (PTFE) is an opaque, white fluoropolymer that is chemically created by free radical polymerization or multiple tetrafluoroethene molecules. PTFE is suitable for a wide range of applications in industries like automotive, aerospace as well as telecom.
PTFE is typically produced in the form of tubes or rods and comprises additives like stainless steel or carbon to boost strength and wear resistance.
If you were looking for a material that displays exceptional resistance to heat, chemicals, electricity while being highly flexible, you are actually looking for PTFE.
The material has a melting point of around 327 degree Celsius and is chemically inert. PTFE is also chemically stable between temperatures as low as -200 degree Celsius and as high as 260 degree Celsius without showing any signs of degradation.
Other highlighting properties of PTFE include:
Exceptional flexural strength, even in low temperatures
In fact, PTFE is so chemically inert that, beyond being reactive to only a few chemicals—that too at high pressure and temperatures—the only thing you need to consider is that high energy radiation.
PTFE molecules tend to start breaking down under high energy radiation.
The biggest advantage of PTFE is its versatility, and the range of applications over so many products and different industries for this material is staggering.
The use of PTFE can have massive benefits in manufacturing and engineering, not just in making tubes or liners for handling or storing corrosive chemicals, but by coating parts such as bearings or screws to increase the lifetime of both the parts themselves and the machinery they are part of.
A PTFE-coated screw will be resistant to corrosion, due to PTFE’s ability to repel water and oil, and lubricated by the material to smoothly drive into whatever surface you are fastening to, with reduced friction, resulting in less wear on both the screw and the surface, and a longer-lasting, more secure finish.
Friction and wear can also be factors with bearings, and a PTFE coat can give the same benefits as with coating screws, with the additional advantage that the coating will also be heat-resistant.
It’s clear that longer lasting, higher-performance parts can add to the efficiency of any machinery, reduce the need to constantly acquire replacement parts, both saving money and the time needed to fit the replacements, as well as reducing waste. This will also reduce maintenance needs as there are less likely to be faults with the equipment, and also greatly reduce, or even eliminate, any expensive manufacturing downtime due to faults or repairs.
Cleaning of equipment can also be reduced in some cases as a PTFE coat is non-wetting, facilitating self-cleaning of parts.
And Teflon textile finishes can even help the environment, because, when applied to fabric, the finish will repel water and oil stains, reducing the need to use dry cleaning, and fabrics will also dry more quickly, using less energy with tumble drying, and last longer due to reduced wear.
With the added advantages that PTFE is non-toxic, has only a minor contraindication for humans from polymer fume fever (only if the temperature of any Teflon-coated pans reaches 260 degrees C) and is FDA approved and food-safe, this material really is of great benefit in many different areas.
