Your Reliable Silicone Oil (Polydimethylsiloxane) Supplier in China
High-Purity Polydimethylsiloxane for Textile Finishing, Plastics & 産業用アプリケーション
KosNature offers a full range of silicone oil (PDMS) with viscosities ranging from 1,000 cps to 12,500 cps, specifically designed for textile finishing, lubrication, emulsification, demolding, and applications in multiple industries (household chemicals, plastics, leather, 塗料, および産業部門).
We have an annual production capacity of 30,000 tons and are capable of providing stable and reliable specifications, clean appearance and consistent batch performance, which has earned the trust of manufacturers worldwide.
Silicone oil remains a core component in textile softeners, 潤滑 剤, amino-modified blends, emulsions and specialty formulations – our PDMS products are designed for formulation teams that require clean quality, reliable viscosity and low acid value, and low volatility performance.

What Is Silicone Oil (PDMS)?
Silicone oil, also known as polydimethylsiloxane (PDMS), is a synthetic high-molecular organosilicon compound. It belongs to “technical functional ingredients for industrial and personal care products” and is also called “liquid plastic”. It has a special structure and is renowned for the following characteristics:
Excellent thermal stability
Good lubricating performance
Strong spreading ability
Excellent electrical insulation
Low surface tension
Non-reactive and non-volatile
High air permeability
Viscosity changes little with temperature
These characteristics make PDMS one of the most widely used raw materials in the following fields:
Textile auxiliaries
Softener formula
Plastic and rubber additives
Personal care products
Lubricants
Industrial coatings
Release agents
Why is silicone oil still the core raw material for textile auxiliaries?
In the textile field, no polymer can match silicone oil in having the following advantages:
1. PDMS offers outstanding softness and hand feel. It is used for low surface tension and can form a uniform lubricating film around the fibers, reducing friction and creating a smooth and silky touch.
2. Thermal stability and shear stability: During pad dyeing, drying and high-speed finishing processes, PDMS can maintain its viscosity and structure. Moreover, it does not decompose or discolor during high-temperature setting (180-200℃), minimizing the yellowing of fabrics at high temperatures.
3. Compatibility with amino modification and emulsification systems PDMS is the base polymer for the following products: amino silicone oil, textile softener, hydrophilic softener, block silicone oil, silicone oil emulsion.
4. Economically and efficiently improving a variety of textile properties, including softness, gentleness to the skin, elasticity, drape, antistatic properties, and fiber protection, PDMS remains an indispensable silicone polymer in textile finishing formulations.

Our silicone oil technology advantages:
1. High-purity PDMS polymer is pure and transparent, with a high flash point, low acid value, low volatility, free of trimethylamine, free of free water, impurities and odors. 2. The strict viscosity tolerance with a batch-to-batch variation of only ±5% ensures excellent chemical stability during emulsification and textile finishing. 3. Excellent transparency and clarity are crucial for high-end textiles and personal care formulas. 4. The flexible formulation performance is compatible with amino modified, epoxy modified, vinyl modified and block silicone oil systems. It has good hydrophobic performance. 5. High oxidation resistance and thermal stability make it suitable for finishing production lines with a maximum temperature of up to 180°C. It has a very high shear resistance capacity. 6. Industrial-grade consistency is perfectly suitable for factories that need to achieve repeatable results in large-scale production
