FRP Core Tube for Copper Foil Winding Core with High Strength and Insulation Applications

product details

Description

The FRP (Fiber Reinforced Plastic) Core Tube is designed for wrapping various plastic films and specialty papers with high precision. Unlike traditional plastic cores such as ABS, or metal cores, the FRP core maintains stable dimensions and surface accuracy under changing environmental conditions, including humidity. Its smooth, flat surface and high structural integrity prevent damage to the wrapped material, ensuring optimal film utilization. FRP cores are customizable in diameter and wall thickness and benefit from decades of proven manufacturing expertise.


Features

  • High Strength: Withstands high loads without deformation.

  • Straight & Circular: Ensures uniform winding without wrinkles.

  • Antistatic: Prevents static damage and hazards.

  • Reusable: Can be used multiple times without quality loss.

  • Durable: Resistant to moisture, corrosion, and impact.


Applications

  • Winding copper foil for secondary battery cathodes (6 µm, 8 µm, 10 µm, 20 µm)

  • Winding aluminum foil for secondary battery anodes (10 µm, 12 µm, 15 µm)

  • Winding separator membranes for secondary batteries (custom thickness)

  • Winding active material electrodes for secondary batteries (custom thickness)

  • Winding metal foils

  • Winding plastic films such as PET, PE, PI

  • Winding high-performance or functional films, including optical films

  • Winding processed films such as vapor-deposited films

  • Winding paper products, labels, and specialty papers
