A wide range of insulation materials brings opportunities for industry development

Insulating materials, also known as dielectrics, refer to materials that do not conduct electricity under the allowable voltage. Insulation materials have high resistivity, which is an important guarantee for the safe and reliable operation of electrical products. According to different material properties, insulating materials can be divided into three categories: liquid insulating materials, solid insulating materials, and gas insulating materials. At present, solid insulation materials dominate the Chinese market.

According to the “2022-2027 Insulation Materials Industry Investment Environment and Investment Prospects Forecast Analysis Report released by the Industrial Research Center, the power industry It is the main application field of insulation materials in my country. The frequent use of household appliances has driven my country’s electricity consumption to continue to grow. According to statistics from the China Electricity Council, my country’s electricity consumption reached 8,331.30 billion kilowatt hours in 2021, an increase of 10.4% over the previous year. With the rapid development of the power industry, the demand for insulation materials, as key materials for the operation of motors and electrical appliances, will continue to grow. In 2021, the size of my country’s insulation materials market will reach 30.12 billion yuan, a year-on-year increase of 13.5%.

Insulating materials are composed of high molecular weight compounds, organic compounds, and inorganic compounds, including polypropylene, styrene, formaldehyde, strong alumina, mica, etc. As a natural mineral, mica is widely distributed in Sichuan, Xinjiang, Inner Mongolia and other places in my country. Mica has insulating and fire-resistant properties, making it an excellent choice for making insulating materials. Driven by market demand, the scale of my country’s mica market continues to increase. In 2021, the scale of my country’s mica market will reach 4.66 billion yuan, a year-on-year increase of 21.6%. Affected by factors such as uneven distribution of production areas and high demand, synthetic mica has gradually occupied a dominant position in the market, which has a positive impact on the development of my country’s insulation materials industry.

Electrical polyester film is a representative product of insulating materials. As a polymer material, the production process of electrical polyester film is relatively complex and requires processes such as drying, extrusion, stretching, slitting, and inspection. The thickness of electrical polyester film is less than 350.0μm. It has the advantages of insulation, tensile strength, chemical resistance, etc., and can be used in combination with other fiber materials. At present, electrical polyester films are widely used in capacitors, transformers, wires, cables and other fields. As nanotechnology continues to make breakthroughs and innovations, the development of my country’s insulation materials industry is facing new opportunities. Nanotechnology is used to combine plasma physics and quantum chemistry to form nanoscale crystal grains inside the polymer. The insulating materials made can be used in military, aerospace and other fields.

Industry analysts said that driven by the rapid development of my country’s power industry, insulation materials, as key materials for the operation of motors and electrical appliances, have continued to gain market space. expand. Our country has a vast territory, widely distributed mineral resources, rich types of raw materials and sufficient supply, which provide support and guarantee for the development of the insulation materials industry. At present, electrical polyester film is the mainstream product in my country’s insulation material market, and its application fields are constantly expanding. With the continuous innovation of production and research and development technology, nano-insulation materials will gain broad market prospects.
