Glossary of seal, gasket, packing and molded rubber parts term of the day: Accelerator ultra
Accelerator Ultra – An accelerator which causes very rapid vulcanization, even at comparatively low temperatures. Tetramethylthiuram disulfide is a typical ultra-accelerator. The dislkyldithiocarbamates and xanthates are also ultra-accelerators.
Glossary of seal, gasket, packing and molded rubber parts term of the day: Accelerator (of vulcanization)
Accelerator (of vulcanization) – Any substance, which hastens the vulcanization of rubber causing it to take place in shorter time or at a lower temperature. In earlier days basic oxides such as limes, litharge and magnesia were recognized as having this function. Nowadays the important accelerators are organic substances containing either nitrogen or sulfur or […]
Glossary of seal, gasket, packing and molded rubber parts term of the day: Abrasion
Abrasion – Surface loss of a material due to frictional forces. The wearing away of a material surface by friction. Particles become detached by a combined cutting, shearing and tearing action. Furnace carbon blacks are the best ingredients found for increasing the resistance of rubber compounds to abrasion. Boost Post
