Vulcanized Fibre Bone Grade

Vulcanized fibre bone grade is the hardest and densest grade available. It offers very high resistance to wear and abrasion. It possesses great mechanical strength. It is also resistant to oils, gasoline and most solvents. It is an electrical grade insulating material capable of withstanding temperatures up to 115ºC. It is used in many mechanical and/or electrical applications such as noiseless gears, cams, cutting blocks, and thrust washers.
