FRP core pipe - Industrial-grade fiberglass reinforced plastic hard core pipe

Jiangsu Hongkai Plastic Technology Co., Ltd is a world-renowned manufacturer and producer of FRP core tubes. What is FRP pipe? FRP core tubes, fully known as Fiberglass Reinforced Plastic core tubes,hereinafter referred to as FRP tubes,are composite core tubes manufactured using glass fiber and its products (such as glass cloth and glass tape) as reinforcing materials, with synthetic resin as the binder, through forming processes like winding.

FRP tubes are commonly used for winding lithium battery separators, which measure only 20–30 microns thick and demand exceptionally high core flatness. The low shrinkage and high dimensional stability of FRP core tubes prevent uneven winding ends, reducing separator loss.

They are also suitable for use as rollers for metal foils such as copper foil and aluminum foil. Their wear resistance and corrosion resistance extend core lifespan and reduce downtime for replacement. In high-precision film winding applications like optical films, incremental films, and ITO films, the surface finish and straightness of FRP core tubes meet the demands of high-end manufacturing.

Some countries also utilize FRP pipes as outdoor insulated fencing. The high resistivity and arc resistance of FRP materials make them an ideal fencing solution for outdoor power facilities, substations, and similar settings, effectively preventing electric shock incidents and ensuring personnel safety.

FRP core tubes, with their high strength, corrosion resistance, and insulation properties, not only hold a central position in the film winding industry but also expand the application boundaries of composite materials in public safety and infrastructure through innovative uses like outdoor insulated fencing. With ongoing advancements in materials science and forming processes, FRP core tubes are evolving toward greater lightweighting, functionalization, and intelligent capabilities, delivering more reliable solutions for industrial manufacturing and public welfare projects.
