In the organosilicon industry chain, low-hydrogen silicone oils serve as key intermediates, silently supporting the synthesis of numerous high-performance materials. Side-chain low-hydrogen silicone oils, with their excellent reactivity, stable hydrogen content, and low volatility, are becoming ideal choices for silicone oil synthesis, silicone rubber crosslinking, and textile auxiliaries.
What is a side-chain low-hydrogen silicone oil?
In simple terms, this is a type of silicone oil with active Si-H bonds in its molecular structure's side chains, and its hydrogen content is adjustable between 0.05% and 1.2%. Side-chain type low-hydrogen silicone oils have three core advantages:
High reactivity: The hydrogen content is precisely controlled in four specifications of 0.18, 0.36, 0.5 and 0.75, which ensures efficient and stable addition reactions with compounds containing unsaturated bonds, providing a reliable foundation for polyether silicone oil, alkyl-modified silicone oil and other products.
Stable hydrogen content: Precise control of hydrogen content avoids product performance instability caused by fluctuations, making your production process more predictable and reliable.
Low volatile matter: volatile matter ≤2%, which reduces volatilization loss during production, storage and use, improves product utilization and reduces environmental impact.
Side-chain low-hydrogen silicone oils have demonstrated outstanding application value in multiple fields.
Silicone rubber crosslinking: As a crosslinking agent for addition-cured silicone rubbers (HTV, RTV), it undergoes an addition reaction with vinyl-based rubber compounds to form a three-dimensional network structure, achieving low-temperature vulcanization, no by-products, and stable performance. It is widely used in high-end products such as sealing rings and medical silicone.
Textile auxiliary synthesis: Used to synthesize hydrophilic polyether silicone oil, which improves the softness, water resistance and breathability of fabrics. It is suitable for high-end clothing and outdoor waterproof fabrics, without affecting the breathability of the fabric.
Polyurethane foam optimization: As a raw material for the synthesis of foam levelers/stabilizers, it improves the uniformity and stability of polyurethane foam, thereby enhancing product quality and consistency.
Enhanced agricultural applications: Used in the synthesis of agricultural spreading agents to enhance the adhesion of pesticides and fertilizers to plant surfaces, thereby improving efficacy and utilization.
Silicone oil emulsification enhancement: As a raw material for the synthesis of silicone oil emulsifiers, it improves emulsification efficiency and stability, and is suitable for silicone oil dispersion in cosmetics and personal care products.
The side-chain low-hydrogen silicone oil series is packaged in 950kg drums and stored at 5℃～30℃, with a standard shelf life of 12 months. The product is a transparent liquid free of mechanical impurities, with a viscosity range of 50-300mm²/s to meet different process requirements.
