FRP Core Tube For Copper Foil

FRP Core Tube(Fiberglass core tube) is a type of core material that uses FRP (fiber-reinforced polymer) as the main structural component. FRP is a composite material that consists of a polymer matrix reinforced with fibers, usually glass, carbon, or aramid. FRP has high strength-to-weight ratio, corrosion resistance, fire resistance, and design flexibility. FRP Core Tube is made by pultrusion process, which involves pulling continuous fibers through a resin bath and a heated die to form a constant cross-section profile. FRP Core Tube materials has high strength, circularity and straightness, antistatic, and semi-permanence characteristics. It is widely used to stably winding thin foil such as secondary battery and high functional optical films.




Technical Parameters

What are the advantages of FRP Core Tube?

FRP Core Tube has many advantages over other core materials, such as wood, paper, or metal. Some of the main advantages are:
High Strength. FRP Core Tube materials has high tensile strength and modulus, which can withstand high loads and stresses without deformation or breakage.
Circularity and Straightness. FRP Core Tube has excellent circularity and straightness, which can ensure smooth and uniform winding of thin foil materials without wrinkles or gaps.
Antistatic. FRP Core Tube has antistatic properties, which can prevent static electricity buildup and discharge that can damage the thin foil materials or cause fire hazards.
Semi-Permanence. FRP Core Tube materials has semi-permanence properties, which means it can be reused for multiple times without losing its performance or quality. This can reduce the waste and cost of core materials.




What are the specifications and uses of FRP Core Tube?

FRP Core Tube has different specifications and uses depending on the application and customer requirements. Some of the common specifications and uses are:
·For secondary battery copper foil winder (cathode). The specification is 6㎛, 8㎛, 10㎛, or 20㎛ thickness. The use is to wind the copper foil that serves as the cathode (negative electrode) of the secondary battery.
·For secondary battery aluminium foil winder (anode). The specification is 10㎛, 12㎛, or 15㎛ thickness. The use is to wind the aluminium foil that serves as the anode (positive electrode) of the secondary battery.
·For separator winder (separation membrane). The specification is any thickness. The use is to wind the separator that serves as the separation membrane between the cathode and anode of the secondary battery.
·For electrode winder. The specification is any thickness. The use is to wind the electrode that serves as the active material of the secondary battery.
