Description

Alkanes, C18-70 is a high-purity, defined mixture of saturated linear and branched hydrocarbons within the C18 to C70 carbon chain range. This product is valued for its exceptional chemical stability, low volatility, and hydrophobic properties, making it a versatile intermediate and performance additive. It is essential for manufacturers in the polymer, lubricant, and specialty chemical industries seeking to enhance product performance and process reliability.

Application

• Polymer & Plastic Additives: Acts as a lubricant, processing aid, and release agent in the production of polyolefins (PP, PE) and engineering plastics.
• Synthetic Lubricants & Greases: Serves as a high-performance base oil or viscosity modifier for specialty lubricants requiring high thermal and oxidative stability.
• Adhesives & Sealants: Used as a plasticizer and water-repelling agent to improve flexibility and moisture resistance in hot-melt and pressure-sensitive formulations.
• Cosmetic & Personal Care: Functions as an emollient and occlusive agent in lipsticks, creams, and lotions to provide texture and skin barrier protection.
• Chemical Intermediate: A key feedstock for the production of chlorinated paraffins, olefins via cracking, and other derivative chemicals.
• Rubber Compounding: Employed as a softener and processing aid to improve filler dispersion and extrusion characteristics in rubber products.
• Specialty Waxes & Coatings: Imparts hardness, gloss, and water resistance in coatings, candles, and investment casting waxes.
• Research & Development: Used as a standard or model compound in chromatographic analysis and materials science research.
