Product Description:
|
|
Pentaerythritol oleate (PETO) is an ideal base oil for No. 68 synthetic ester flame resistance hydraulic oil; At room temperature, it appears as a pale yellow or light brown transparent viscous liquid. Its molecular structure contains polyols bonded with unsaturated fatty acid esters, which feature excellent lubrication properties, high viscosity index, good flame resistance, and a biodegradation rate of over 90%; It is one of the core raw materials for high-performance industrial oils.
l Outstanding lubrication performance: High viscosity index ensures stable lubrication across a wide temperature range.
l Excellent flame resistance: High flash point and low volatility ensure safe use in high-temperature environments.
l Eco-degradable: Biodegradable rate exceeds 90 %,complying with stringent environmental regulations.
