G10 epoxy board is a high-performance material made of specially formulated epoxy resin and glass fiber cloth through a lamination process. It not only fully inherits the basic insulation advantages of epoxy board, but also achieves significant optimization and improvement in multiple key performance dimensions. It has higher dielectric strength and lower dielectric constant, which enables G10 epoxy board to maintain stable and reliable insulation performance in high voltage environment, effectively ensuring the safe operation of electrical systems.

Six core performances of G10 epoxy board

Top flame retardant performance: G10 epoxy board has reached the industry's highest flame retardant grade standard of UL94V0. This means that when encountering a burning situation, the material can quickly self-extinguish in a very short time, minimize the risk of fire, and build a solid protective barrier for the safety of life and property. It is this excellent feature that makes it occupy an important position in the manufacture of high-end electrical insulation parts.

Stable electrical performance: Whether in a dry environment or facing humid working conditions, G10 epoxy board can always maintain excellent electrical performance, and stably play an insulating role in various complex electrical environments, which is an ideal choice for electrical insulation parts.

Excellent mechanical properties: Even in a high temperature environment, G10 epoxy board can still maintain good mechanical properties. It has high hardness and strength, which can effectively resist external stress impact, and ensure the structural integrity of the equipment.

Environmental compliance standards: G10 epoxy sheet strictly follows the EU halogen-free environmental protection standards, meets the development requirements of modern society for green environmental protection. And in the process of production and application, it not only meets performance requirements, but also takes into account eco-friendliness.

Flexible processing performance: G10 epoxy board has good processing adaptability and can be customized to produce products of different colors and specifications according to the diverse needs of customers, fully meeting various personalized application scenarios.

Wide application adaptation: From electronic and electrical insulation parts to high-end transportation tools such as airplanes and trains, to power equipment such as transformers, G10 epoxy board has a wide range of applications.
