Profile: Shanghai PRO's Chemical Industrial Ltd. is a manufacturer & exporter of ethylene propylene monomer (EPM), polyisobutylene (PIB) and lubricant additives. Our products include ethylene propylene co-polymer, turbine oil additive, low based synthetic calcium sulfonate, calcium alkyl salicylate, tricresyl phosphate, ammonium thiophsphonate, polyisobutylene double succimide, zinc dialkyl dithio phosphate, 2.6-di-tertiary butyl para-cresol, petroleum barium sulfonate and liquid benzotriazole derivative. Petroleum barium sulfonate is primarily used in anti-rust oils such as replacement-type anti-rust oil, inter-process rust oil, seal oil, anti-rust lubricating oil, and anti-corrosion grease as anti-rust agent. It is a brown viscous liquid or semi-solid. 2.6-di-tertiary butyl para-cresol is primarily used in industrial lubricating oils such as turbine oil, transformer oil, hydraulic oil and machine oil, serving as anti-oxidant & anti-gel inhibitor. It can also be used in petrochemical products such as rubber & plastics, acting as anti-aging agent. It is a white crystal. Amine epoxide condensate is a kind of effective demulsifier. It is primarily used in blending gear oil, steam turbine oil, anti-wear hydraulic oil, compressor oil and other lubricating oils which are likely to come in contact with water in service. It is a dark brownish red liquid. Alkyl naphthalene is primarily used in blending internal combustion engine oil, axle oil and mild-dewaxing lubricating oil. It is a brownish-red thick liquid.
