Fumaric Acid And Vinyl Acetate Pour Point Depressant Additives,Paraffin Oil Pour Point Depressant
Ultra-Concentrated Cold Flow Improver for Extreme Environments
It is an orange yellow transparent thick liquid. It shows exceptional pour point depression ability, increasing viscosity ability and improving the viscosity index. These advanced pour point depressant additives can substitute for traditional solutions in the most demanding applications.
Product Introduction
T818C is a hyper-concentrated fumarate copolymer pour point depressant engineered to deliver unparalleled low-temperature performance in synthetic, bio-based, and high-paraffinic lubricants. Leveraging advanced molecular design with crystalline modifiers, it suppresses wax formation down to -70°C and enables reliable cold-start operations in arctic/mining applications. Exceeds MIL-PRF-32073 Grade 7 requirements for military/aviation fluids.
- Record Low-Temperature Fluidity
Achieves -70°C pour point (ASTM D5949) and MRV TP-1 ≤30,000 cP @ -65°C (ASTM D4684).
- Paraffin Tolerance
Controls wax crystallization in ≥35% paraffinic base oils (DSC WAT reduction ≥25°C).
- Ultra-Low Treat Rate Efficiency
50% lower dosage vs. conventional PPDs (effective at 0.05–0.3%).
- Bio-Integrated Formulation
100% biodegradable (OECD 301F) with zero aquatic toxicity (LC50 >100 mg/L).
- Shear/Pressure Stability
SSI ≤5 (ASTM D6278); maintains viscosity in 50,000 psi hydraulic systems.
Application
T818C pour point depressant additives are used primarily for various industrial oils and engine oils requiring extreme low-temperature performance:
