Introduction to Hydroxyl Silicone Oil

Hydroxyl silicone oil, also known as α,ω-dihydroxy polydimethylsiloxane (PDMS), is a highly versatile silicone polymer characterized by reactive hydroxyl (-OH) groups at both ends of its molecular chain. Its unique structure enables it to serve as a key raw material in various industries, including adhesives, coatings, textiles, and medical applications. With excellent thermal stability, electrical insulation, and chemical inertness, hydroxyl silicone oil is a preferred choice for engineers and manufacturers seeking high-performance silicone solutions.

Key Features and Properties

Hydroxyl silicone oil stands out due to its exceptional physical and chemical properties:

• Thermal Stability: Performs reliably in a wide temperature range (-50°C to +250°C), making it ideal for extreme environments.

• Low Viscosity-Temperature Coefficient: Maintains stable viscosity across different temperatures, ensuring consistent performance.

• Hydrophobic & Moisture-Resistant: Repels water and prevents moisture absorption, enhancing durability in humid conditions.

• Excellent Electrical Insulation: Widely used in electronics due to its high dielectric strength.

• Low Surface Tension: Improves wetting and spreading properties in coatings and adhesives.

• Physiologically Inert: Safe for medical and cosmetic applications.

Applications of Hydroxyl Silicone Oil

Thanks to its reactive hydroxyl groups, hydroxyl silicone oil can be further modified or crosslinked into elastomers, films, and specialty materials. Key applications include:

• Silicone Rubber Production: Acts as a base material for 107 silicone rubber (when viscosity exceeds 2500 mPa·s).

• Adhesives & Sealants: Enhances flexibility and adhesion in high-performance formulations.

• Textile & Leather Treatment: Provides water repellency and softness.

• Cosmetics & Personal Care: Used in skincare products for its smooth, non-greasy texture.

• Electronics: Protects circuits due to its insulating and heat-resistant properties.

Why Choose Hydroxyl Silicone Oil?

Whether you need a heat-resistant lubricant, a waterproofing agent, or a flexible elastomer precursor, hydroxyl silicone oil delivers unmatched performance. Its chemical inertness, biocompatibility, and adaptability make it indispensable across industries.
