1. Dimethyl silicone oil is generally used on pet release film for insulation.

2. Pet silicone oil film, also known as pet release film, is to coat a layer of silicone oil on the surface of PET film to reduce the adhesion of PET film surface and achieve the effect of release. It can be divided into single-sided release film and double-sided release film. According to the release force, it can be divided into light release film, medium release film and heavy release film.

3. Silicone oil usually refers to the linear polysiloxane products that keep liquid state at room temperature. Generally, it can be divided into two types: methyl silicone oil and modified silicone oil. The most commonly used silicone oil - methyl silicone oil, also known as common silicone oil, its organic groups are all methyl. Methyl silicone oil has good chemical stability, insulation and hydrophobicity. It is made of dimethyldichlorosilane by hydrolysis with water to produce primary polycondensation ring. The ring body is cracked and rectified to produce low ring body. Then the ring body, head sealing agent and catalyst are put together for polycondensation to obtain a variety of mixtures with different degrees of polymerization. After the low boiling matter is removed by vacuum distillation, silicone oil can be produced.

Pet is a milky white or pre yellow highly crystalline polymer with smooth and glossy surface. Not resistant to hot water immersion and alkali. Silicone oil has excellent heat resistance, electrical insulation, weather resistance, hydrophobicity, physiological inertia and small surface tension. In addition, it has low viscosity temperature coefficient and high compression resistance. Silicone oil plays an auxiliary role in the protection of PET sheet
