Polyether Modified Silicone Oil: 4 Main Features


    Polyether modified silicone oil is a kind of silicone nonionic surfactant with unique properties formed by graft copolymerization of polyether and dimethyl siloxane. In the production of products, a variety of silicone surfactants with different properties can be obtained by modifying the number of silicone oil chains or changing the ratio of polyether Eo to Po and changing its chain number and terminal groups to meet a variety of industries Need.

    Characteristics of polyether modified silicone oil:

    1. Has good lubricity, suitable for making high-grade cutting fluid.

    2. It has lower surface tension and is suitable for anti-fogging agent.

    3. Better softness and antistatic properties, suitable for fabric softener.

    4. Good leveling property, suitable for adding in a variety of resins (polyurethane resin, paint resin, plastic resin, etc.), can improve the intermolecular stress of these resins, and overcome the shortcomings of these resins, Get new performance.

    At present, most domestic silicone products are consumed in China. Silicone deep-processing products include silicone oil, silicone rubber, silicone resin and silane coupling agent, among which the demand for silicone rubber and silane coupling agent accounts for 87%. The silicone surfactant is a type of hydrophobic main chain of polydimethylsiloxane, which is formed by linking one or more organic polar groups (such as polyether chain, carboxyl group, etc.) in the middle or terminal position of the hydrophobic main chain Surfactant. Silicone surfactants not only have the general properties of ordinary surfactants, because of the Si elements and organic groups contained in their molecular structure, it also has high temperature resistance, compatibility, physiological inertness, non-toxicity, wetting properties, energy The characteristics of reducing surface tension, defoaming and foam stabilizing performance are widely used in industrial production. Silicone oil refers to a linear polysiloxane product that remains in a liquid state at room temperature. According to different chemical structures, silicone oil can be divided into methyl silicone oil and modified silicone oil. Methyl silicone oil is the most traditional silicone oil product; modified silicone oil replaces some of the methyl groups in methyl silicone oil with an organic group, thereby improving certain properties of silicone oil and adapting to various uses. Modified silicone oil is usually With higher economic added value. The market scale of my country's polyether modified silicone oil in 2017 was 3.45 billion yuan.

    For domestic enterprises, according to the statistics of the production and sales of polyether-modified silicone oil companies in China, it is found that the production of surfactants of various companies is mostly greater than the sales volume, and due to the entry of foreign companies, it is expected that China's polyether modification in the next few years The supply of silicone oil and surfactant will be greater than the demand.
