A lubricant composition with excellent high-temperature operability, the lubricant composition including: 85 wt % to 95 wt % of a polyalkylene glycol base oil; 1 wt % to 5 wt % of an antioxidant; 1 wt % to 5 wt % of a first anti-wear extreme-pressure additive; and 1 wt % to 5 wt % of a second anti-wear extreme-pressure additive, wherein the antioxidant includes an amine-based compound, the first anti-wear extreme-pressure additive includes an amine salt of phosphate, and the second anti-wear extreme-pressure additive includes a nano-diamond dispersion.

Lubricant composition for brake system

A method of manufacturing a coupler for an air suspension includes: preparing a topping cord sheet and a rubber band; connecting the topping cord sheet and the rubber band to each other by attaching the rubber band to an outer circumferential surface of the topping cord sheet; and vulcanizing an intermediately formed body made by the connecting of the topping cord sheet and the rubber band to each other.

Coupler for air suspension and apparatus and method for manufacturing the same

Disclosed are a silicone rubber composition and a preparation method thereof. The silicone rubber composition comprises a polydimethylvinylsiloxane, a silica filler, a polymethylvinylsiloxane oil, a hydrogen-modified polyorganosiloxane, a platinum-based catalyst, and a polymethylhydrogensiloxane vulcanizing agent.

Silicone rubber composition and manufacturing method thereof

Disclosed is a rubber composition for flexible coupling. In particular, the rubber composition for flexible coupling is prepared by mixing a filler including an HNBR alloy and carbon blacks having different average particle diameters with a hydrogenated acrylonitrile-butadiene rubber such that performance deterioration due to hydrolysis can be prevented even in hot and humid environments and the rubber composition has superior heat resistance and improved mechanical strength.
