1. Phenylmethylsiliconefluid is the product obtained by replacing some methyl groups in methyl silicone oil with phenyl groups. It has a low thermal expansion coefficient. 2. Phenylmethyl silicone oil is a composite silicone oil that introduces phenyl groups into the molecular chain of dimethylsiloxane. Compared with methyl silicone oil, it has better high-temperature resistance, radiation resistance, lubrication performance and solubility, with a working temperature range of -50℃ to 250℃.
2. Methylphenyl silicone oil and phenyl silicone oil are the same substance - silicone oil. It has many special properties, such as low viscosity, resistance to high and low temperatures, oxidation resistance, high flash point, low volatility, good insulation, low surface tension, no corrosion to metals, and non-toxic. Due to these characteristics, silicone oil has excellent effects in many applications. Among various silicone oils, methyl silicone oil is the most widely used and is the most important variety, followed by methylphenyl silicone oil. Various functional silicone oils and modified silicone oils are mainly used for special purposes. Properties: Colorless, odorless, non-toxic, and non-volatile liquid. Applications: Various different viscosities. High heat resistance, water resistance, electrical insulation, and low surface tension. Commonly used as high-grade lubricating oil, shock-proof oil, insulating oil, defoamer, release agent, polishing agent, isolator, and vacuum diffusion pump oil; emulsions can be used for polishing of car tires and dashboard. Methyl silicone oil is the most commonly used. After emulsification or modification, it is used for smooth and soft hand feel finishing on textiles and post-treatment of textiles, and also added to shampoos in daily care products to improve hair lubricity. In addition, there are ethyl silicone oil, methylphenyl silicone oil, acrylate silicone oil, polyether modified silicone oil (water-soluble silicone oil), etc.
