Applications

Chemical Resistance :

TUFFLON PTFE products are inert to almost all known chemicals even at as high temperature as upto 2600C continuous and pressures, imparting excellent chemical resistance to all the Acids (including highly corrosive strong inorgenic acids) Alkalies, organic chemicals, all known solvents. Except that it is effected bylementry Fluorine, strong fluorinating agents (Such as chlorine trifluoride) and molten alkali metals.

Gaskets, ‘O' rings, Flat ‘V' rings, seals, Valve and pump diaphgrams components for valves & pumps, impellers, pipe expansion joints, stirrers, pistons rings, plugs and balls for valves, floats for rotameters, balls for Non-return valve, laboratory beakers, crucibles, mechanical seals, nuts and bolts etc.

Electrical Resistance :

Tufflon PTFE products are very good electrical insulating material having high volume and surface resistivity, high dielectric strength, very low dielectric constant and dissipation factor. It has got highest tracking resistance rating and very good high voltage arc resistance. Its corona resistance is good.

Various Tufflon machined components are used in electrical and electronic industries such as High tension bushings and insulators in high voltage switchgear (because of Tufflon PTFE's very goof arc and traching resistance), Nozzle and outlet orifices of high tension power switches operating with sulphur hexa fluoride, Hermetic seals, for capacitors, pacers for co-axial cables, brush holders in collector motors, valve and cathode holders, Transistor sockets, plug connections, conductor bushing, insulating bushing, soldering terminals, slot insulation of motors, insulation in commutators and coil and transformer insulations etc.

Heat/Temperature Resistance and Cryogenic Stability :

Tufflon PTFE components have the highest thermal stability amongst all other commercially available plastics or fluoropolymers. Tufflon PTFE components can be used continuously at temperatures ranging from 200⁰C to 260⁰C retaining good tensile strength, flexibility and elasticity making it fully serviceable under moderate loads. It can be used for intermittent service temp. upto 300⁰C depending upon mechanical stresses involved.
Tufflon PTFE products will withstand severe temperature extremes without loss of physical properties and can be used at – 206⁰C also (i.e. t.p. of liquid helium) without undergoing embrittlement.

Components for non lubricated gas compressors such as Piston rings Rider rings, valve disc guide, electrical insulations and insulation bushing of various types where high temperatures are involved, components for Nuclear plant equipments and reactors, ball valve rings, piping and reactor gaskets, expansion bellows etc.

Friction Resistance :

Tufflon PTFE products have the lowest co-efficient of friction, in dynamic and static applications it is the same, amongst all solid materials. This is because of very low intermolecular forces in PTFE due to the high bond energy between carbon and fluorine atoms. Actual co-efficient of friction depends on number of factors such as loading pressure and sliding speed, the opposing material, type of lubricant if used and for most practical applications it is 0.1 to 9.25 combined with this property it has got very good physical and mechanical properties.
Even Tufflon filled PTFE containing 5% to 40% by volume of fillers such as Glass fibre, bronze, carbon, graphite, solo or in combination have such low friction co-efficient and with increased surface hardness and other physical properties.

Dry running Bearings, self lubricating bushes, seals for stuffing boxes on rotating shaft, oil seal rings, washers, gaskets, parts for pneumatic equipment gears, valve seals, parts for non-lubricating gas compressors such as Piston Rings, Rider Rings, non-lubricated plug valve sleeve, wedges etc. As a anti-friction bearing plates for bridges, loads in corrosive liquids, building industry, pipe bridges etc. where PTFE as load bearing constructional material as well as that of solid lubricant.

Non-Stick Properties :

Tufflon PTFE products, as a result of very low intermolecular forces, due to high bond energy between Fluorine and Carbon atoms and the low polarazibility of fluorine atoms, do not adhere or stic to other materials giving rise to excellent NON-/stick properties.

For handling sticky fluid or substance e.g. laboratory beakers, flexible hose, loose sleeves for rollers used in Backery and food industry etc.

Non Taxicity :

Tufflon PTFE products, being highly inert to virtually all organic and inorganic chemicals are non toxic in nature and is safe for contact with edibles, drugs and pharmaceuticals etc.

Laboratory beakers, pharmaceutical bottles, bottle Tufflon PTFE products, due to its thermal resistance

Weather Resistance :

Tufflon PTFE products, due to its thermal resistance chemical inertness, resistance to ultraviolet rays, ozone and general industrial atmospheric conditions, exhibits excellent weather resistances.
