Description

Polysiloxan CAS NO 9011-19-2 is a versatile class of synthetic polymers characterized by a backbone of alternating silicon and oxygen atoms, often with organic side groups. This unique structure provides exceptional thermal stability, low surface tension, and high flexibility across a wide temperature range, making it a critical performance additive and base material. It is essential for manufacturers seeking to enhance product durability, impart water repellency, or modify rheological properties. Key industries that rely on this material include personal care, coatings, adhesives, and industrial lubricants.

Application

• As a key ingredient in personal care products such as shampoos, conditioners, and skin creams to provide smoothness and emolliency.
• As a release agent and lubricant in industrial molding processes for plastics, rubber, and metals.
• As a modifying agent in coatings, paints, and sealants to improve water repellency, gloss, and weather resistance.
• As a defoamer and anti-foaming agent in aqueous systems for pulp/paper, wastewater treatment, and chemical processing.
• As a dielectric fluid or heat transfer medium in specialized electrical and thermal management applications.
• As a base polymer for silicone rubbers, adhesives, and sealants requiring flexibility and stability.
• As a surface treatment agent for textiles, fibers, and construction materials to impart stain and moisture resistance.
