JDVII-663 Viscosity Index Improver
JDVII-663 is a polyhydrogenated styrene–isoprene‑type viscosity index improver. It exhibits excellent permanent shear stability, outstanding low‑temperature fluidity, and ideal high‑temperature, high‑shear performance, while also demonstrating good compatibility with pour point depressants. This additive can be formulated into multigrade oils that meet the specifications of modern gasoline and diesel engines and is suitable for use in a wide range of base oils, including synthetic oils.
JDVII-665 Viscosity Index Improver
JDVII-665 is a polyhydrogenated styrene–isoprene‑type viscosity index improver. It exhibits excellent low‑temperature fluidity, ideal high‑temperature, high‑shear performance, and good compatibility with pour‑point depressants. With outstanding permanent shear stability, it is suitable for use in long‑life engine oils. This additive can be formulated into multigrade oils that meet the specifications of modern gasoline and diesel engines and is compatible with a wide range of base oils, including synthetic oils.
JDVII-6738 Poly(methyl methacrylate)-type viscosity index improver
JDVII-6738 is a solution of polymethyl methacrylate in highly refined mineral oil. It is a high-shear‑stable viscosity index improver specifically formulated for blending into transmission oils, offering dual functionality—improving the viscosity index while reducing pour point—while maintaining shear stability, thereby effectively reducing formulation costs.
JDVII-6831 Poly(methyl acrylate)-type viscosity index improver
JDVII-6831 is a solution of polymethyl methacrylate in highly refined mineral oil. It is a viscosity index improver specifically formulated for hydraulic fluids, offering exceptional shear stability.
JDVII-6831E Poly(methyl methacrylate)-type viscosity index improver
JDVII-6831E is a solution of polymethyl methacrylate in highly refined mineral oil, serving as a viscosity index improver with excellent shear stability. It requires a lower dosage in formulating low‑temperature hydraulic fluids and other lubricants, delivering outstanding cold‑flow performance. JDVII-6831E effectively raises the viscosity index of lubricants, reduces the amount of pour‑point depressant needed, and offers competitive pricing. Compared with similar foreign products, it provides significant cost advantages, helping customers achieve substantial savings in production expenses.
JDPPD-8256 pour point depressant
JDPPD-8158 poly(methyl methacrylate)-based pour point depressant, manufactured using advanced technology and high‑grade fatty alcohols as raw materials. This product delivers excellent pour point reduction for both paraffinic and intermediate‑base oils, with outstanding low‑temperature performance.
JDPPD-8256E polymethyl methacrylate pour point depressant
JDPPD-8248 is a highly effective poly(methyl methacrylate)-based pour‑point depressant for lubricating oils. It delivers excellent pour‑point reduction across paraffinic and intermediate‑base oils, particularly hydrogen‑refined base stocks, while also providing superior low‑temperature performance and improving the viscosity index. Its performance is comparable to that of leading international products. This product is suitable for a wide range of applications, including aviation hydraulic fluids, fluid‑power transmission oils, gear oils, transformer oils, low‑pour hydraulic oils, hydraulic oils for CNC machine tools, specialty hydraulic fluids, and internal‑combustion engine oils.
JDFM‑855 features a non‑sulfur‑phosphorus molybdate structure and, as an oil‑soluble liquid organic molybdenum friction modifier, can significantly reduce the coefficient of friction in crankcase oils, engine oils, and other lubricants. In synergy with sulfur‑containing additives, it markedly enhances the lubricant’s friction‑reducing and anti‑wear performance. It also effectively inhibits oxidative degradation of the lubricant and exhibits excellent antioxidant synergism when combined with aromatic amine antioxidants. This product is free of sulfur and phosphorus, delivering superior performance while promoting energy efficiency and environmental protection.
JDMD-DMTD thiazole n-octyl mercaptan condensation product
JDMD-DMTD is an important chemical intermediate, and its derivatives are widely used in the pharmaceutical, lubricant and grease, metalworking fluid, and rubber industries. Common chemical reactions include: double displacement reactions with soluble salts; salt‑formation reactions with alkali metal hydroxides; oxidation of thiol groups; addition reactions with organic compounds containing reactive double bonds; reactions with oxygen‑containing functional groups; reactions with aldehydes and alcohols; salt‑formation reactions with amines and aqueous ammonia; and reactions with acyl chlorides.
JDEP-TPPT Extreme Pressure Additives
JDEP-TPPT also known as triphenyl thiophosphate, is a ash-free extreme pressure anti-wear agent, can be widely used in anti-wear hydraulic oil, oil film bearing oil, hydraulic transmission oil and turbine oil and other oil products as anti-wear agent.
