Behind the reliable operation of electrical equipment, industrial machinery, renewable energy systems, and modern electronic devices lies a critical yet often overlooked component—insulation materials.

Mica Board is manufactured by bonding mica paper with organic silicone adhesive, followed by heating and hot pressing. It is a high-performance electrical insulation and thermal insulation material. The available colors are typically gold and white.

Mica Paper is widely recognized as a “core material” in high-temperature electrical insulation applications. With its outstanding thermal resistance, electrical insulation performance, and stable chemical properties, it plays a critical role in modern electrical, industrial, and high-tech engineering systems.

In the field of non-standard component manufacturing, material selection often defines the performance limits and application scope of the final product. As a high-performance electrical insulation material, Mica Board is bringing breakthrough solutions to custom-engineered parts across multiple industries due to its outstanding heat resistance, electrical insulation performance, and mechanical stability.

Epoxy Glass Sheet is manufactured using electronic-grade alkali-free fiberglass fabric impregnated with epoxy resin and other modified materials, followed by high-temperature and high-pressure lamination. Epoxy Glass Sheets feature excellent electrical insulation, flame retardancy, high temperature resistance, and strong mechanical performance.

FR-4, which we commonly refer to in the PCB industry, is not actually a specific material name. It is a flame-retardant grade designation.

Phenolic Cotton Cloth Laminate is manufactured by impregnating cotton fabric with phenolic resin, followed by curing under heat and pressure. It is classified as a Thermal Class E insulating material and provides excellent mechanical properties, oil resistance, and reliable dielectric performance.

Epoxy Sheets are widely used in electrical and electronic applications due to their excellent combination of heat resistance, corrosion resistance, wear resistance, light weight, and electrical insulation properties.

Bakelite sheet, also known as Phenolic Paper Laminated Sheet, is manufactured using high-quality bleached wood pulp paper and cotton linter paper as reinforcing materials. These substrates are impregnated with phenolic resin produced from high-purity synthetic petrochemical raw materials and then processed through heat and pressure lamination.

Electrical resistance is the reciprocal of conductance, and resistivity refers to the resistance per unit volume of a material. The lower the conductivity of a material, the higher its resistance. For Electrical Insulation Materials, higher resistivity is always preferred. A higher resistivity indicates better insulation performance and lower leakage current under electrical stress.
