COMPO HCAF 211 GG is one of the "COMPO" range of Non asbestos friction materials. It is rigid moulded product dark grey in colour and having short filaments of steel and non - metallic substances in a random dispersion and uses a specially developed resin as matrix which contributes to both the strength and performance of material. This material is produced only in flat sheet form and suitable for use under dry or oi immersed operating conditions HCAF 211 GG has medium friction with excellent fade and wear resistance. It machines well and suitable for use at a variety of duty levels, yielding consistent performance characteristic. This material is manufactured with ground finish on both surfaces, so may be bonded on either side.

• Industrial disc. brakes.
• Industrial clutches.
• Tractor steering clutches.

The continuous temperature quoted is for constant slip condition. It is possible to exceed the recommended maximum continuous temperature for intermittent applications upto 225oC for long periods.

Carbide tipped tools are recommended for use with this material for drilling, turning and boring.
