Description

Allyl Stearate is a long-chain fatty acid ester derived from stearic acid and allyl alcohol, characterized by its unsaturated allyl group. This unique structure makes it a valuable intermediate and functional monomer, offering properties like internal plasticization and cross-linking capability. It is primarily used in the production of specialty polymers, lubricant additives, and as a chemical building block for the synthesis of other esters and surfactants.

Application

• Polymer & Resin Modification: Acts as a reactive diluent and internal plasticizer in the production of allyl resins, unsaturated polyester resins, and coatings to improve flexibility and processing.
• Lubricant & Grease Formulation: Serves as a synthetic ester base oil or additive in high-performance lubricants and metalworking fluids, offering good lubricity and thermal stability.
• Surface Active Agents: Used as an intermediate in the synthesis of specialized surfactants and emulsifiers for industrial and cosmetic applications.
• Cross-linking Agent: Utilized in cross-linking reactions for polymers and elastomers to enhance mechanical properties, chemical resistance, and durability.
• Chemical Synthesis: Functions as a versatile chemical intermediate for producing other allyl esters, flavor/fragrance compounds, and pharmaceutical precursors.
• Adhesive & Sealant Formulations: Incorporated to modify the rheology and cure properties of adhesives, sealants, and caulks.
