ABS Core Pipes

JSHKcores’ ABS core tubes are precision-manufactured core consumables that have undergone professional validation at production line level, produced by a leading Chinese manufacturer with decades of experience in ABS extrusion moulding. Following 12 months of rigorous on-production-line testing (in high-speed winding applications for lithium-ion battery separators, high-end optical films and electronic copper foil), at an average winding speed of 100–120 m/min, this core tube has been proven to reduce winding runout by 25%–30%, provide a clean winding environment free from particulate contamination, and improve winding yield by 40%. As a trusted supplier of plastic core tubes, JSHKcores strictly adheres to the quality control standards of its own cleanroom facilities, ensuring that every ABS core tube meets the stringent requirements of lithium-ion battery manufacturers, optical film producers and electronic copper foil manufacturers.

Product Description

ABS core tubes are hollow, tubular cores extruded using an extruder from ABS resin (acrylonitrile-butadiene-styrene copolymer). Their primary purpose is to serve as a winding carrier for roll materials such as film, membranes, adhesive tape, copper foil and electrode sheets—in other words, they are the ‘spools’ found on production lines.

JSHKCORES is one of the top five manufacturers in China’s ABS core tubes industry. Its products are exported to dozens of countries and regions worldwide, and the company has established long-term, stable partnerships with numerous Fortune 500 companies and industry leaders.Our current partners include leading companies such as SEMCORP, Juhe New Material and Sinoma Lithium Membrane. Lithium-ion battery separator winding is a key application—during the winding process, the separator is wound onto an ABS core tube.

A Comparison of the Core Materials of ABS Core Tubes and Paper Tubes

Comparison Dimension	ABS Core tubes	Paper Tubes
Strength & Load Capacity	High strength and high rigidity; capable of supporting large-diameter, heavy-weight rolls without deformation or collapse.	Relatively low strength and hardness; limited load capacity; prone to crushing and deformation under heavy loads.
Impact Resistance	Excellent toughness; effectively absorbs impact forces and is highly resistant to damage during handling and transportation.	Highly brittle; susceptible to cracking and breaking upon collision or dropping.
Moisture Resistance	Completely non-absorbent; maintains stable performance in humid environments.	Strongly absorbent; strength drops drastically when exposed to moisture, making it prone to deformation and mold growth.
Temperature Resistance	Excellent high- and low-temperature resistance; remains stable within a range of -40°C to 70°C.	Poor temperature adaptability; tends to soften at high temperatures and become brittle at low temperatures.
Surface Quality	Smooth inner and outer walls with a low friction coefficient; will not scratch the rolled materials.	Relatively rough surface; may shed fibers that can scratch sensitive materials.
Cleanliness	Dust-free and lint-free; suitable for Class 10,000 or even Class 1,000 cleanrooms.	Prone to generating paper lint and dust; cleanliness struggles to meet high-end requirements.
Dimensional Precision	High precision (straightness up to 0.15mm/m, ovality ≤0.3mm).	Lower precision; prone to wobbling and misalignment during high-speed operations.
Service Life	Reusable dozens of times or more; long lifespan.	Basically single-use; non-reusable.
Anti-static Properties	Anti-static functionality can be achieved through formulation adjustments.	Lacks anti-static capabilities.
Environmental Friendliness	Recyclable and reusable in a circular economy.	Biodegradable, but involves massive single-use consumption.
