(Bone Grade) Vulcanized fibre, bone grade is the hardest and most dense 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 115° C. It is used in many mechanical and/or electrical applications such as noiseless gears, cams, cutting blocks, and thrust washers. |
