Isostearic acid for rubber and plastics is a functional additive primarily composed of branched C18 fatty acids, produced through the catalytic hydrogenation and isomerization of natural unsaturated fatty acids (such as oleic acid and ricinoleic acid). Its molecular structure is a methyl-branched octadecanoic acid, possessing unique properties such as a low melting point (liquid at room temperature), high oxidative stability, and excellent polymer compatibility. Compared to traditional straight-chain stearic acid, the branched structure provides better low-temperature fluidity and interfacial compatibility with polar/non-polar polymers. In the rubber and plastics industry, isostearic acid is mainly used as a plasticizer, lubricant, dispersant, mold release agent, and stabilizer. It can improve the processing fluidity of polymer materials, reduce melt viscosity, improve filler dispersibility, and impart excellent flexibility and weather resistance to finished products.
The raw material system for isostearic acid uses natural vegetable oils as the core starting material, mainly derived from renewable resources such as castor oil (primarily produced in India and China), palm oil (Southeast Asia), and rapeseed oil (Europe and Canada). Unsaturated fatty acids (such as oleic acid and ricinoleic acid) are converted into branched isostearic acid through a high-pressure hydrogenation-isomerization process. During production, the vegetable oil is first hydrogenated to saturation under the action of a nickel or precious metal catalyst, and then undergoes skeletal isomerization on an acidic catalyst (such as a molecular sieve) to form C18 fatty acids with methyl branches. Finally, it is purified to lubricant-grade specifications (acid value typically controlled at 190-200 mgKOH/g, color <200 APHA) through vacuum distillation and molecular distillation.
In terms of cost structure, raw material costs account for the largest share (approximately 60-70%). Castor oil, in particular, is significantly affected by monsoon climates and export policies due to its global supply being concentrated in India (accounting for over 90% of global production). Energy consumption and catalyst consumption are major factors in processing costs, especially high-precision isomerization, which requires expensive molecular sieve catalysts and high-pressure reaction equipment. Furthermore, quality control and certification costs are increasing. To meet API, ACEA, and other lubricant specifications, as well as biodegradability certifications (such as OECD 301B), companies need to invest heavily in product testing and sustainable supply chain audits. Compared to petrochemical-based synthetic fatty acids, natural-based isostearic acid enjoys a premium in European and American markets due to its renewable raw materials and good biodegradability (28-day biodegradation rate >60%), but its production costs are correspondingly 20-30% higher.
