| Product Overview
This ester is produced by reacting neopentyl polyols with saturated fatty acids under specific, proprietary process conditions, followed by a specialized post‑treatment purification step. It is a sterically hindered polyol ester that exhibits exceptionally high oxidation stability and excellent anti‑wear performance, along with superior solvency. Its key functions include: dissolving poorly soluble additives to achieve additive balance; and breaking down carbon deposits to help keep the engine clean. Common compatible base oils include PAO and GTL, with typical addition levels of 5–15%.
| Product Features
- Excellent lubricity
- High oxidation stability and thermal stability
- Excellent hydrolytic stability
- Excellent low-temperature performance
- Low volatility, low carbon deposition
- Biodegradable, DCD 65%
- Excellent solvency; it swells rubber, enhances the solubility of poorly soluble additives, and increases the solubility of residual carbon, while maintaining cleanliness.
| Scope of Application
General‑purpose automotive engine oil (mineral oil + G2835): 5–15%; Premium automotive engine oil (PAO/GTL + G2835): 5–25%; Industrial gear oils and wind‑turbine gear oils: 5–10%.
Adding this neopentyl polyol ester to internal‑combustion engine oils can extend oil‑change intervals and improve fuel economy. The high polarity of the synthetic ester enables it to adsorb exceptionally well at the friction interface, delivering immediate performance during startup—when 90% of mechanical wear occurs. G2835 ester exhibits excellent oxidation stability, low volatility, and low residual carbon, further prolonging oil‑change intervals. Its superior lubricity and reduced friction contribute to outstanding fuel efficiency.
