Epoxy Glass Sheet boasts outstanding comprehensive performance, featuring high temperature resistance, corrosion resistance, high mechanical strength, superior machinability, low water absorption, reliable insulation and excellent electrical properties. There are various types of Epoxy Glass Sheet available, including 3240, G11, FR-4, G10 and so on.
Nowadays, transportation is highly convenient, and subways as well as high-speed railways have become indispensable travel tools. Machined parts made of insulating materials are widely adopted in railway construction, and such insulating materials can fully meet the requirements of harsh service environments.
Machined Epoxy Glass Sheet components for railway use are arc-resistant, easy to machine and flame retardant. They can operate stably at 150℃ and own excellent chemical resistance without being corroded when exposed to acid and alkali solutions. If ignition occurs under excessive temperature, its flame retardant property allows the material to self-extinguish once separated from open flame. Furthermore, machined Epoxy Glass Sheet parts have great wear resistance and extended service life, which can drastically cut the cost of component replacement.
Epoxy Glass Sheet, also known as epoxy fiberglass sheet, is a composite material formed by embedding or wrapping glass fiber materials with epoxy resin. Compared with ordinary glass fiber materials, epoxy fiberglass composites possess superior properties such as high tensile strength, high elastic modulus, excellent impact resistance, stable chemical performance, good fatigue resistance and high temperature resistance. They are widely used in aerospace, construction, chemical engineering, agriculture and other industries.
1. Diverse forms Various systems composed of resin, curing agent and modifier can adapt to molding requirements of different applications, covering materials ranging from ultra-low viscosity liquids to high-melting-point solids.
2. Convenient curing By matching different curing agents, epoxy resin systems can realize curing within the temperature range of 0℃ to 180℃.
3. Strong adhesion Polar hydroxyl groups and ether bonds contained in the molecular chains of epoxy resin endow it with strong adhesion to all kinds of substances. Epoxy resin features low shrinkage during curing and generates minor internal stress, which further improves bonding strength.
4. Low shrinkage rate The reaction between epoxy resin and curing agent proceeds via direct addition reaction or ring-opening polymerization of epoxy groups in resin molecules, without releasing water or other volatile by-products. Compared with unsaturated polyester resin and phenolic resin, epoxy resin achieves an extremely low shrinkage rate (less than 2%) during curing.

Against the backdrop of global energy transition, new energy vehicles are reshaping the landscape of the traditional automotive industry at an unprecedented pace. As core components of new energy vehicles, batteries, traction motors and charging infrastructure have growing demand for insulating materials. As a critical type of insulating material, Insulation Sheet plays an irreplaceable role in the new energy vehicle sector.
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.
