gear oil EP extreme pressure antiwear additive SIB Sulfurized Isobutylene

GALX-321 Sulfurized Isobutylene/SIB
CAS NO.:68511-50-2

Description
GALX-321 is an extremely effective EP antiwear additive and deemed as main component in today’s gear oils. With high content of active Sulfur, GALX-321 could provide the oils with excellent EP and load-carrying properties. It is useful in protecting equipment under shock-load conditions and working surfaces which experience high loads. GALX-321 has good oil solubility, light color, less corrosion for the metals and fine compatibilities with the compounds containing phosphorus. GALX-321 can be widely used for formulating middle-grade and top-grade automotive gear oils and industrial gear oils, the metal processing oils, drilling machine oils, etc. As GALX-321 is an excellent source of controlled activity sulfur. It could be used in lubricating grease applications where EP and load-carrying capabilities are required.
CAS NO.:68511-50-2
