K 2013: Gharda Plastics showcasing friction and wear polymeric materials

Gharda Plastics, headquartered in Mumbai, India, was the first Indian company manufacturing high performance friction and wear polymeric materials to showcase its products at K 2013.

Gharda Plastics, the engineering polymers business of Gharda Chemicals Ltd., is launching a specialty lubricious solution for industrial and business equipment, incorporating various reinforcements in G-PAEK and GAZOLE grades. This collaborative development with other industrial partners is aimed at applications that require very high wear resistance. G-PAEK product family is based on Polyetherketone (PEK) and GAZOLE represents newly commercialized thermoplastic alloys of PEK and polybenzimidazole (PBI).

The two featured wear grades, G-PAEK 1230FCT and GAZOLE 6430FCT are easy-flow for injection molding of intricate multi-cavity parts. The heat deflection temperature of 350oC - 360oC makes them suitable for demanding high heat resistance applications. The company says these are far superior in performance to the commercially available engineering alternatives of polyetherimides (PEI), polyimide (PI), polyphenylenesulphide (PPS), polyetheretherketone (PEEK) and exhibit exceptional properties, creep properties, and dimensional stability. PTFE has a low coefficient of friction, however its wear resistance especially at high temperatures, is poor. The FCT grades also have low coefficient of friction, and display low wear rates even at high temperatures.

The comparable specific flexural strength of FCT grades to metals provides a significant cost savings opportunity to the manufacturer. The high performance thermoplastics offer weight savings, easy machining and molding options with greater design flexibility. This allows the customer to produce parts with challenging geometries as required. It eliminates the costly production steps necessary for metals.

The high fatigue strength and wear resistance with temperature make FCT grades suitable for automotive/transportation segment for gears, bearing and bushings. Other key applications of FCT grades are in printer parts and textile parts such as thrust pads, roller bearings and dry lubricating bushings that are continuously moving at low to high speeds and at high temperatures.
