Application Scope

Pentaerythritol reacts with fatty acids to form fatty acid esters, which are used primarily in the production of high-quality synthetic lubricants. This type of lubricant is heat resistant and is commonly used in the lubrication of jet aircraft engines.


Pentaerythritol is mainly used in military aircraft and civil aviation. In addition, there is an increasing demand for pentaerythritol fatty acid ester lubricants in the production of new ozone-friendly refrigerants, leading to continued growth in downstream development efforts.

The antioxidant produced from pentaerythritol exhibits excellent thermal protection and processing stability for rubber and plastics. It prevents discoloration in polymers by inhibiting degradation. This antioxidant is widely used in plastics (PE, PP, PS, PVC), synthetic fibers, ABS resin, rubber, lubricants, and more, providing long-term thermal stability for polymers. The demand for this product continues to grow.

Alkyd resin, which is derived from pentaerythritol, is the most widely used in paint coatings. Alkyd resin sales account for 68% of total pentaerythritol sales volume. It is sold to the construction and automotive industries worldwide.
