Dioctyl Alkyl Zinc Dithiophosphate Zddp Additives
Advanced Anti-Wear Protection for High-Pressure & Biofuel Systems
Premium ZDDP Additives for Industrial Protection
These premium ZDDP additives have excellent anti-oxygen and anti-corrosion properties, excellent anti-emulsification properties, storage stability and hydrolysis stability, but also have certain anti-wear properties. The alkaline component content of these ZDDP additives is higher than that of T203, with excellent high temperature stability. They are used for blending high quality diesel engine oil and marine oil, especially suitable for medium and high grade low-temperature anti-wear hydraulic oil and industrial oil.
Product Introduction
This Dioctyl Zinc Dithiophosphate (ZDDP) delivers superior anti-wear protection through optimized C8 alkyl chains for enhanced thermal stability and hydrolytic resistance. These advanced ZDDP additives are engineered for modern high-pressure systems and biofuel compatibility, forming resilient tribofilms that prevent scuffing while resisting acid attack from ethanol/biodiesel blends.
Key Technologies
- Extreme Pressure Shield
Achieves 550 kg weld load (ASTM D2783) with 40% lower phosphorus than standard ZDDP.
- Bio-Acid Resistance
Maintains antiwear properties in B30/E20 fuels (FZG Scuffing Test Stage 14 validated).
- Oxidation Inhibition
3x extended oxidation life vs. conventional ZDDP (ASTM D943 modified).
- Hydrolytic Stability
<5% hydrolysis after 100h at 95°C/5% water (ASTM D2619).
- Copper Compatibility
Passes 1000h copper corrosion test at 150°C (ASTM D130 modified).
