PE core pipe - Special engineering pipe material

Jiangsu Hongkai Plastic Technology Co., Ltd. ranks among China's top 10 manufacturers of PE core tubes, supplying high-toughness, impact-resistant plastic winding cores to packaging film and tape producers. Our products carry SGS certification and are the preferred supplier for cleanroom environments.

PE core tubes demonstrate significant application value in the film industry due to their unique technical advantages: In terms of chemical resistance, they withstand corrosion from acids, alkalis, salts, and most organic solvents (excluding only a few strong oxidizing agents like concentrated sulfuric acid and concentrated nitric acid), with no risk of electrochemical corrosion. During film production, they maintain shape integrity when continuously exposed to solvents such as plasticizers, toluene, and methyl ethyl ketone, reducing maintenance costs by 70%. Mechanical properties: With a bending strength of 69-110 MPa, HDPE core tubes support high-speed winding at 500 m/min without deformation, meeting the demands of high-precision applications like lithium battery separators and optical films. Their elongation at break exceeds 500%, resisting rupture under heavy crushing loads. With four times the abrasion resistance of steel tubes, they withstand high-frequency friction during film slitting and rewinding operations. Processing and installation: Supports extrusion molding with customizable diameters (φ0.3mm–φ175mm), wall thicknesses (φ0.1mm–φ153mm), and lengths to fit production lines of varying scales. Heat-fused or electrofusion joints exceed the strength of the pipe body. with overall costs reduced by over 30% compared to metal pipes. Waste materials are recyclable, meeting green building material standards.
