Description

Poly(Vinyl Stearyl Ether) is a high-molecular-weight polymer derived from vinyl stearyl ether monomers. This compound is valued for its excellent hydrophobic properties and its ability to act as a versatile modifier and lubricant in various formulations. It is particularly sought after by manufacturers in the cosmetics, personal care, coatings, and plastics industries for its ability to enhance texture, improve water resistance, and reduce surface friction.

Application

• Cosmetic & Personal Care: Used as a thickening agent, emollient, and water-repellent additive in creams, lotions, lipsticks, and sunscreens.
• Polymer & Plastics Modification: Acts as an internal lubricant and processing aid to improve flow properties and mold release in polymer compounding.
• Surface Coatings & Inks: Imparts water resistance and enhances slip properties in paints, varnishes, and printing inks.
• Textile & Fiber Treatment: Serves as a softening agent and water-repellent finish for fabrics and non-woven materials.
• Adhesives & Sealants: Functions as a rheology modifier and hydrophobic agent to improve performance and durability.
• Industrial Lubricants: Used as an additive in specialty greases and lubricants to reduce friction and wear.
