Phenolic cotton cloth laminate sheet is widely used in new energy vehicles, especially in battery systems, electric drive units, electronic control systems, and structural components. Thanks to its high mechanical strength, excellent insulation, heat resistance, and resistance to oil and chemicals, it serves as a reliable structural and functional material in various critical areas.

Battery Systems (Power Battery Modules and Packs)

Insulation gaskets between battery cells

Support plates, side panels, and positioning blocks in battery modules

Cushioning pads and reinforcement boards inside battery enclosures

Function:

Provide structural support and prevent cell movement

Electrically isolate battery cells and connectors

Offer thermal protection and flame resistance for safer battery operation

Electric Drive System (Motors and Gearboxes)

Insulation rings and stator supports inside electric motors

Spacer pads between motor end covers and housings

Gaskets and buffer plates in gearboxes or electric drive casings

Function:

Ensure insulation for high-voltage windings and safe motor operation

Absorb vibration and improve running stability

Resist oil, grease, and high temperatures in lubricated environments

Electronic Control Units (MCUs, Power Modules, Chargers)

Insulating barriers and mounting plates inside control units

Support sheets around IGBT modules

Gaskets and interface plates for high-voltage connectors

Function:

Electrically isolate components and prevent short circuits

Improve mechanical fixation and resist thermal deformation

Enhance reliability and safety of power electronics

Vehicle Body and Interior Components

Sliding pads in seat rails and shock-absorbing gaskets

Base plates and backing sheets for electronic assemblies

Reinforcement pieces in lightweight structural parts

Function:

Reduce noise and vibration, improving cabin comfort

Replace metal parts to reduce vehicle weight

Maintain long-term durability and heat resistance
