Description

(75-76% Polydimethylsiloxane)-Ethylene Copolymer, 80-120 Cst is a specialized organosilicon copolymer engineered to deliver a unique balance of silicone and organic polymer characteristics. This product matters for formulators seeking to enhance the lubricity, release properties, and thermal stability of their materials without compromising compatibility. It is particularly needed by manufacturers in the personal care, coatings, and industrial lubricant sectors for creating high-performance, durable formulations.

Application

• Personal Care & Cosmetics: Acts as a premium conditioning agent and emollient in hair care products, skin creams, and sunscreens, providing a non-greasy, smooth feel and improved spreadability.
• Release Agents & Mold Lubricants: Used in plastic, rubber, and composite manufacturing to facilitate easy demolding and prevent sticking, ensuring high surface quality of finished parts.
• Industrial Lubricants & Greases: Serves as a base or additive fluid to enhance lubricity, reduce friction, and improve thermal-oxidative stability in specialized mechanical applications.
• Coatings & Inks: Incorporated as a flow and leveling agent or a slip additive to improve surface smoothness, scratch resistance, and water repellency.
• Textile & Fiber Treatment: Applied as a softener and water repellent finish for fabrics, enhancing handle and durability.
• Adhesives & Sealants: Functions as a plasticizer and processing aid to modify rheology, improve flexibility, and enhance weathering resistance.
