  • What are physical and chemical properties PTFE?

The Main Properties of PTFE Other useful PTFE properties are its high flexural strength, even in low temperatures, high electrical resistance and dielectric strength, resistance to water (owing to fluorine’s high electronegativity), and low coefficient of friction.

What is PTFE gasket material?

Virgin grade PTFE gaskets are made from 100% pure material which is used in most general applications. It is extremely soft and formable and is often used for chemical resistant seals and gaskets. It is made directly from the resin producer and has never been processed into a shape.

What chemical properties does PTFE have?

PTFE is composed of carbon and fluorine. PTFE properties include high molecular weight, hydrophobility, low coefficient of friction, thermoplasticity, good dielectric properties, high electronegativity, and low chemical reactivity. The high molecular weight is a function of being a polymer.

What type of material is PTFE?

fluoropolymer
PTFE (polytetrefluoroethylene) is a soft, low friction fluoropolymer with outstanding chemical resistance and weathering resistance. PTFE is stable at temperatures up to 500oF and it is often used in high temperature environments. PTFE also has excellent electrical insulating properties.

How strong is PTFE?

Polytetrafluoroethylene (PTFE) Material Properties

Property Metric English
Yield Strength 1.97e7 – 2.17e7 2.86 – 3.15
Tensile Strength 2.07e7 – 3.45e7 5-Mar
Elongation 2.0 – 4.0 200 – 400
Hardness (Vickers) 5.79e7 – 7e6 5.9 – 6.5

Where is PTFE gasket used?

PTFE gaskets are used in equipment handling chemicals and petrochemicals because they are resistant to corrosive fluids and extreme temperature extremes. Except for certain alkali metals and fluorine compounds, PTFE demonstrate resistance to most chemicals at various pressures and temperatures.

What are physical and chemical properties PTFE?

As is known to all, polytetrafluoroethylene (PTFE) as engineer materials has excellent physical and chemical properties, such as outstanding thermal stability (1) and toughness at low temperature (2), low thermal conductivity, perfect insulating and dielectric properties (3), extremely low coefficient of friction (4) …

What is PTFE resistant to?

Chemical Resistance of Virgin PTFE: The chemical resistance of Virgin PTFE is excellent. It is stable in most aggressive and corrosive media, exceptions being liquid or dissolved alkali metals, flourine and other extremely potent oxidisers.
