What is capacitor paper?

Capacitor paper is generally composed of cellulose and special additives. Cellulose is the main component, which is an organic macromolecular compound extracted from natural plant fibers or wood. Additives include resins, fillers, lubricants, etc., which can give better physical and chemical properties to capacitor paper.

Characteristics of capacitor paper

Excellent insulation performance: Capacitor paper has extremely high electrical insulation strength, which can effectively isolate the two electrodes in the capacitor and prevent the current from passing directly, thus ensuring the normal operation of the capacitor.

Good chemical stability: Capacitor paper is specially treated in the production process and has excellent chemical stability, which can resist the erosion of various chemical substances and maintain the stability of its insulation performance.

High mechanical strength: Capacitor paper has a high mechanical strength. It can withstand the pressure and tension generated by the capacitor in the working process to prevent the failure of the capacitor due to mechanical deformation.

Good electrolyte absorption: In electrolytic capacitors, capacitor paper, as the adsorption carrier of the electrolyte, can fully absorb and retain the electrolyte, thus ensuring the capacitive performance and stability of the capacitor.

Low impurity content: The raw materials and process of the capacitor paper are strictly controlled in the production process to ensure that the impurity content of copper, iron and other impurities contained in it is extremely low, so as to avoid adverse effects on the performance of the capacitor.

The use of capacitor paper

1. Capacitor separator

The capacitor separator is one of the important components inside the capacitor, which is used to isolate the granular media between the two electrodes of the capacitor. Capacitor paper, as the manufacturing material of the separator, has good mechanical strength and electrical insulation properties, which can ensure the long-term stable operation of the capacitor.

2. Materials for cable protection

As an insulating material, capacitor paper can be made into an important base material of cable insulation layer and outer protective layer by composite technology. The base material can improve the voltage resistance, wear resistance, impact resistance and other properties of the cable, and extend the service life of the cable.

3. Power electronics

Capacitor paper can also be used to produce electronic components, such as DC power supplies, AC filters, electronic switching capacitors, etc., which play an important role in electronic circuits as auxiliary capacitors and electrical insulation layers. Thet has good stability and high frequency response ability.

Capacitor paper is a kind of paper material with excellent electrical insulation properties and mechanical strength, which plays a crucial role in capacitor manufacturing. By optimizing its raw material selection and production process, the performance and quality of capacitor paper can be further improved to meet the demand for high-performance capacitors in different industries. At the same time, the application field of capacitor paper is also expanding and deepening, providing strong support for the development of many industries such as power, electronics, and communications. In the future, with the continuous progress of science and technology and the continuous development of the industry, the performance and application fields of capacitor paper are expected to further expand and innovate.
