Silica fibre braided high temperature insulation rope The best choice for thermal insulation—withstands up to 1,260°C continuous temperature Much better substitute to conventional asbestos ropes, which are not meant for use over 450°C More effective than ceramic and glass rope High grade silica fibre resists elevated temperature for longer duration without any thermal degradation Practically unaffected by direct flame, hot blast, molten metal, welding sparks and flux Zero loss on ignition Saves energy loss, reduces downtimes

Rolgard® is a unique high-performance and high-temperature lithium based grease reinforced with PTFE. Rolgard® deposits a fine, tenacious, clinging film on the applied metal surface and the innumerable micro particles of PTFE act as tiny ball bearings that help minimise friction and temperature buildup. The presence of PTFE in Rolgard® helps propagate smoother movement between movable and interfacing parts even at high speeds and temperatures. The grease is known to be mechanically and chemically stable, providing effective lubrication at temperatures upto 250°C Excellent for all metal to metal lubrication Chemically and mechanically stable. Does not soften or harden, unlike ordinary greases Excellent thermal stability. Resists oil separation and does not migrate from hot surfaces Withstands a wide temperature range, –5 to +250°C Excellent shear stability. Remains where originally applied for extended periods Reduces friction and wear Cuts wasteful energy consumption Controls heat build-up. Safeguards your precious equipment Reduces noise and vibration, especially in large gears Contains no chlorine which has been known to promote corrosion Contains no silicone which has been known to cause migration problems High di-electric strength Offers greater malleability than graphite, MoS2 and other solid lubricants Joints treated with Rolgard® are easily dismantled, even after years Increases life of equipment Minimises downtime and maintenance costs

Expanded PTFE joint sealant tape with self-adhesive backing strip A non-staining and non-contaminating sealant for use in pipe flange A low friction sealant with excellent chemical resistance, even against strong acids and caustics Wide application in refineries and other industries

GRAPHITE BUSH WITH SS EYELET Flexible graphite sleeve with SS eyelet Made by compressing spirally wrapped graphite tapes and SS eyelet High purity of graphite with low chloride, sulphur, fluoride, ash content etc with no binders Self lubricating packing with extremely low friction characteristics, resistant to water, steam and oil Suitable for high pressure and high temperature applications. Packing sleeves are used in many brands of gauge cock, to prevent leakage and to ensure effective operation. The controlled compression ensures a standard, quality product

Glass fibre rope made from glass fibre yarn Excellent insulation rope that offers good flexibility, dimensional stability and high tensile strength Resistance to many acids and alkalis, most bleaches and solvents

Expanded PTFE sheet gasket A non-staining and non-contaminating sealant for use in pipe flange A low friction sealant with excellent chemical resistance, even against strong acids and caustics Wide application in refineries and other industries

Ceramic fibre braided high temperature insulation rope reinforced with e-glass fibre The best choice for thermal insulation Withstands up to 1,260°C Much better substitute for conventional asbestos ropes, which are not meant for use over 450°C Manifold service life in comparison to the life than asbestos ropes Very low loss upon ignition Saves energy loss, reduces downtimes

Ceramic fibre woven cloth reinforced with e-glass fibre Excellent insulation cloth that withstands up to 1,250°C Much better substitute of conventional asbestos cloth which are not meant for use over 450°C Manifold service life in comparison to the life of asbestos cloth Very low loss upon ignition Available in rolls, thickness of 2 mm, 3 mm and 5 mm etc; width of 1 m SS wire reinforced rope cloth available upon request
