PETS Pentaerythritol Stearate is a fatty acid ester of pentaerythritol used as an industrial ingredient in formulated chemical systems. Identified by CAS No. 115-83-3, this material functions through its esterified long-chain structure, providing lubricity and surface modification within solid and semi-solid formulation matrices. It is commonly applied in lubricant formulations where controlled friction behavior and processing stability are required at an industrial formulation level. Supply is available with competitive factory pricing, supports customized specifications, and includes MSDS, TDS, COA documentation for bulk supply.
