Our clutch appliances have the following characteristics: Made of asbestos or Non-asbestos material and other high quality compound; Not only saturated in a phenolic resin, but have a second saturated in a silicate, which imparts high heat resistance to the friction paper; Designed with a softer, more resilient base paper; Designed to dissipate oil without the necessity of an oil groove; Increased surface area for increased holding, heat absorption and for shorter lock-up time decreasing slippage Performance is superior: durable, stable friction performance, good wear resistance, high burst strength, but less wear against opposing steel plate; Without noise and public harms; ISO9001/QS9000 Certificated.
