Financial News, May 15, 2025 – According to information from the National Intellectual Property Administration, Jiangsu Wenli New Material Technology Co., Ltd. has applied for a patent titled "A Preparation Method of Polyether-Modified Silicone Oil for Antistatic Agents," with publication number CN119978384A and a filing date of March 2025.
The patent abstract reveals a disclosed preparation method for polyether-modified silicone oil used in antistatic agents, comprising the following steps:
S1: The raw materials for polyether-modified silicone oil (by weight) include:

• 100–150 parts of high-hydrogen silicone oil
• 50–100 parts of octamethylcyclotetrasiloxane
• 50–100 parts of hexamethyldisiloxane
• 1–5 parts of catalyst
• 80–100 parts of allyl polyether
• 100–150 parts of nitrogen
• 30–50 parts of white oil
• 5–15 parts of dodecanol
• 1–5 parts of polyether activation catalyst

S2: Mix the high-hydrogen silicone oil, octamethylcyclotetrasiloxane, hexamethyldisiloxane, and catalyst from S1, and conduct ring-opening polymerization rearrangement under catalyst catalysis to obtain a mixed solution.
S3: Filter the mixed solution from S2 to obtain low-hydrogen silicone oil.
The polyether-modified silicone oil prepared by this invention features low impurities and light color, resulting in high-purity products with excellent performance.
According to Tianyancha data, Jiangsu Wenli New Material Technology Co., Ltd. was established in 2018 and is headquartered in Suzhou, specializing in science and technology promotion and application services. The company has a registered capital of 10 million RMB. Tianyancha’s big data analysis shows the company has made equity investments in 3 enterprises, holds 1 trademark, owns 15 patent applications, and has obtained 6 administrative permits.
