PTFE is a material of remarkable properties : Nonstick, friction free, self lubricating, non-wettable, nonflammable, non brittle, non-toxic, resistant to atmospheric conditions, resistant to fungus growth are some of its major properties. Its electrical properties are equally outstanding. All properties are maintained over a wide temperature range -200⁰c to +360⁰c.

FIBRE GLASS too is a material of remarkable properties. Fabrics made from continuous filament yarn exhibit superior properties in terms of high tensile strength, low elongation, high temperature resistance etc.

A combination of both produces a unique blend PTFE/GLASS CLOTH, retaining all the properties of both the constituents. It is highly suitable for manufacturing conveyor belts for high temperature resistance etc.

Polypropylenecopolymers have outstanding chemical resistance and show the highest resistance of all thermoplastics to organic chemicals. High densitypolypropylenehas some similarity with Polypropylene co-polymers in respect of chemicals resistance, although here againPolypropyleneco-polymers possesses the additional advantages of being usable at higher operating temperature. Both the polymers have similar solubility parameters and tend to swell by the same solvents. In both the cases the absence of any possible interaction between the crystalline polymer and the liquid prevents solution of the polymers in any liquid at room temperature. Polypropylene copolymers also possess an extremely high resistance to inorganic environments. It is not attacked by aqueous solution of inorganic salts not by most mineral acids and bases, even when in concentrated form, though it is liable to be attacked by oxidising agents e.g. 100% fuming Nitric acid and Sulphuric acid or the halogens.

Constructions:
An extremely low friction extruded soft and dense packing made grade of PTFE, graphite and high temperature lubricant.

PTFE thread seal tapescan be used as a sealant in all types of threaded pipe materials like iron, steel, copper, aluminum, special steel, plastics including PVC pipes. Apart from these, the most important characteristics ofPTFE tapesto be used as a thread sealant are the tensile strength properties and the density. Performance of the tape is determined by the balance of tensile strength and elongation between the longitudinal and transverse directions & the percentage elongation at break in the transverse direction. Good drape is the ability of the thread seal tape to conform closely to the pipe threads without tearing.

An extremely low friction extruded soft and dense packing made grade of PTFE, graphite and high temperature lubricant.

Constructions:
PTFE yarn coated with graphite and lubricated with an inert high temperature lubricant.

Applications:

Constructions:
A packing with a center of hollow silicon core or solid silicon cord braided around by yarn of style 51, 62, 71, 82 & 83

Applications:

A specially developed packing for use on rotating equipments with excessive shaft deviation. It also reduces shaft / sleeve wear. The center of silicon core / cord gives it strong restoration properties and exerts back-pressure, resulting in total sealing. This packing is suitable for pumps, reactors, mixers, agitators, etc.

Constructions:
High tensile yarn made from a special grade PTFE, impregnated with PTFE dispersion and lubricated with inert high temperature lubricant.

Nylon rodssquare & round profile are characterised by a combination of high strength, toughness & abrasion resistance. Other advantages are low weight, non-corrosive, low co-efficient of friction, true self-lubricating effect, vibration & noise damping etc. Parts fabricated out of nylon replaces metal parts such as Bush, Bearing, Slide plates, Gears, Gear Racks, Wear plates, Washers, Gaskets, Seals, Sleeper pads for rolling Mills, Liners, Wheels, Sleeves, Pulleys, Ropeway, Tyres, Rollers etc which are originally fabricated out of Phosphor bronze, Gum metal, Brass, White metal, steel & other expensive Metals.

Extruded Nylon- Grade is suitable for general purpose
Nylon + MoS2 :Nylon with controlled quantity of MoS2 (Molybdenum disulphide) to enhance sliding (Wear) and self lubrication properties, better out door performance achieved (UV radiation) in Black colour
