Why Use PTFE As A Sealing Material?

2019-04-29

  PTFE which is Polytetrafluoroethylene is flexible and durable elastomer that offers average tensile strength and has a remarkable chemical resistance at the same time, with the excellent electrically and thermally resistive properties. With the molecule level, the PTFE gasket manufacturers also produce the materials that have some carbon atoms chain where two fluoro atoms are bonded each on a carbon. The bonded fluoroatoms help in surrounding carbon chain which creates a very dense molecule that has strong bonds of carbon-fluorine and the structure of polymer which is inserted too many chemicals.Why Use PTFE As A Sealing Material?

1. The Best Chemical Resistance

PTFE gasket manufacturers manufactured PTFE material as the best chemical resistant. The very pure materials of these kinds are applied in very corrosive areas, and you will be sure that sensitive mediums won't be contaminated. The material has high insolubility level with its intrinsic purity level is high too which can be manufactured without any contamination for any corrosive or rather ultra-pure applications. They are resistant by being attacked with any types of chemicals only having molten alkali metals as the exceptions with some fluorine compounds that are at the elevated pressures and temperatures. The material can’t is affected by any lubricants, rocket/aircraft fuel, hydraulic fluids, at various atmospheric conditions.

2. It Is A Versatile Material For  R.S.L Sealing

PTFE or rather Teflon has unique properties which make it become the best choice if you are looking for the best gasket for food grades. It has carbon atoms with long chain in its atomic level of which everyone has been linked to two atoms of fluorine. Their linkage is very strong that makes PTFE not to bond to any other thing, making it non-sticky. The material can be used at 260 degrees Fluorine temperature, and they melt above 635 degrees Fluorine. It is flexible in its lower level below freezing, which may go up to -100 degrees fluorine, as per the formulation. The material is the best insulator in electricity. The gasket does not absorb water which makes it inert biologically in relevant applications. They resist any chemical attack like disinfecting agents and aggressive cleaning.

 

3. PTFE Sealing Alternatives

There are materials whose properties almost resemble PTFE or are superior in some ways compared to PTFE. As for silicone, its flexible with low temperature has a high-temperature limit on its upper, and great compress-ability. But it isn't the best with steam, that is necessary for most applications like food packaging places. It has no acid resistant either, chlorinated solvents, and to alkalies, this makes it be limited as per its potential for being the best gasket for foods.

 

4. Best Corrosion resistance

The media which is not compatible with the rubber compounds, corrosive or caustic chemicals may make PTFE be the best to use. It is the best in almost all industrial chemicals, and this is because it is the very best gasket for resisting corrosion materials that are in various industries. PTFE is also best when the rubber compound integrity has been compromised with some chemical attacks.

 

5. Has Long shelf-life

PTFE material is the best in applications which require extended or long-life service intervals, especially in very corrosive places. Elastomers in other materials can survive for a short period and degrade with time which may result to various issues as time goes by, but as for resistance of PTFE, they are good to serve you for a long period.

 

6. Has Wide Range Of temperature

The capability range temperature of PTFE materials always is between (-325 to +500) degrees of Fluorine which is the best when compared to the ranges of other elastomers. When applied in higher temperatures or cryogenics like the combustion and oven processes may rule any elastomer components out which identifies the PTFE gasket manufacturers as the best gasket materials producers. Very low temperatures may cause various rubber compounds to be hardened until the place that elastomeric features are not available anymore to the material. When the contracted materials are combined with this, it will mean that it doesn't function effectively for the seal. Also, PTFE may retain pliability and flexibility properties even when they are at their cryogenic temperatures. The PTFE gasket manufacturers produce the best gasket materials which have got best uses when compared to other materials. You should try it out, and you will know their benefits.
