Packing and storage
Powder: 20kg or 25kg/bag, flakes: 25kg/bag. Packed in woven bag with plastic liner inside, or in kraft paper bag with plastic liner inside. Resin should be stored in a cool, dry and well ventilated place far away from heat source to avoid moisture and caking. The shelf life is 4-6 months below 20℃. Its color will become dark with the storage time, which will do no influence on the resin performance.
Clutch facings are a friction material used with clutch discs. They assist the clutch in starting and stopping the energy flow between a driven shaft and a drive shaft. They do so via a low coefficient of friction. Because they work with a lower coefficient of friction than similar friction materials, they create exceptionally quiet, stable and smooth systems.
Brake linings are layers of friction material bonded to and lining brake shoes. Brake linings are heat resistant, keeping the friction they create from causing sparks or fire.
Brake pads, also known as brake bands, consist of a metal plate bonded to a friction surface, such as a brake lining. Brake pads are available in a wide range of configurations, such as drum brake pads and disc brake pads.
