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.
Core Applications of Insulation Sheet in New Energy Vehicles
1. Battery Systems: Primary Application Scenario for Insulation Sheet
The battery is the "heart" of new energy vehicles, while Insulation Sheet acts as the safety guardian for stable battery operation. Within battery modules, Insulation Sheet is widely adopted for battery separators, pack housings and internal structural components.
Battery separators: Insulation Sheet effectively prevents internal short circuits and extends the cycle life and safety performance of batteries.
Housings and structural parts: Used in battery pack casings, Insulation Sheet delivers thermal insulation and mechanical protection. It also provides flame retardant performance in case of thermal runaway, buying precious escape time for vehicle occupants.
2. Traction Motors: Guarantee for Efficient Operation
Traction motors of new energy vehicles are required to run stably for long durations under high-voltage and high-current conditions, where insulating materials perform a decisive function. Protected by Insulation Sheet, electric current is isolated reliably to avoid electric leakage and short circuits, sustaining efficient motor operation.
3. Charging Infrastructure: Safety Barrier for Power Transmission
In charging facilities, Insulation Sheet is extensively applied to key components including charging plugs, vehicle connectors and cables.
Charging plugs and connectors: Insulation Sheet offers reliable electrical isolation to secure the whole charging process.
Cables and wire harnesses: Insulation Sheet wrapped around cables blocks current leakage and shields against external environmental interference, ensuring stable power transmission.
Other Applications of Insulation Sheet
Beyond core power systems of new energy vehicles, Insulation Sheet is also applied to many invisible auto parts. For instance, the inner core of automotive sun visors, which people tend to overlook, is processed from epoxy sheet with embedded magnets. Epoxy sheet sun visor cores feature high temperature resistance, anti-aging properties and lightweight design, greatly extending service life. It is also used for parking signs and numerous hidden auto components waiting to be discovered.

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.
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.
