{"product_id":"cabsehr","title":"Economic Hydrophilic PP or PP\/Cellulose Roll (T40-140 um * W110 mm * L10 m) as Aqueous Battery Separator, CABSEHR","description":"\u003cp\u003eFor aqueous battery systems—such as aqueous zinc-ion, aqueous lithium-ion, or advanced alkaline batteries—standard polypropylene (PP) separators are highly problematic due to their inherent hydrophobicity. Because water has high surface tension, an untreated PP membrane will resist electrolyte wetting, leading to high interfacial resistance and poor ion transport. To bridge this gap, manufacturing roll-to-roll separators requires either surface-modified hydrophilic PP or a PP\/cellulose composite framework.\u003c\/p\u003e\n\u003cp\u003eHydrophilic PP rolls are standard polyolefin membranes that have undergone chemical or physical surface modification to introduce polar, water-loving functional groups.Typically achieved via plasma treatment, UV-grafting of hydrophilic monomers (like acrylic acid or acrylamide), or surfactant coating. The advantage is retaining the excellent mechanical tensile strength, uniform pore structure, and low thickness (typically 15–25 um) of industrial PP. It prevents the rapid mechanical degradation common in purely organic or water-soluble polymers. The disadvantage is surfactant coatings can gradually leach into the aqueous electrolyte over extended cycling, causing a loss of hydrophilicity and potential foaming or side reactions. Grafted or plasma-treated variants offer much higher long-term stability.\u003c\/p\u003e\n\u003cp\u003ePP\/cellulose blends combine the robust mechanical skeleton of polypropylene with the exceptional natural wettability and high porosity of cellulose fibers. These are often structured as non-woven mats or laminated membranes. The Matrix Structure: Cellulose provides an open, highly porous network with abundant hydroxyl (-OH) groups that naturally bond with water molecules, ensuring instantaneous electrolyte absorption. The PP component (either interwoven fibers or a base layer) provides the necessary wet tensile strength to survive tension on automated roll-to-roll battery assembly lines.\u003c\/p\u003e\n\u003ctable style=\"width: 105.207%; height: 343.6px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 28.5414%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 37.5898%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCABSEHPPR (C-ABS-EHPPR)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 33.3219%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCABSEHPPCR (C-ABS-EHPPCR)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 55.2px;\"\u003e\n\u003ctd style=\"width: 28.5414%; height: 55.2px;\"\u003e\u003cem\u003eMaterial\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 37.5898%; height: 55.2px;\"\u003e\n\u003cp\u003ePP (Polypropylene) with surface treatment for hydrophilic property\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 33.3219%; height: 55.2px;\"\u003e\n\u003cp\u003ePP\/Cellulose composite with good hydrophilic property\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 74.8px;\"\u003e\n\u003ctd style=\"width: 28.5414%; height: 74.8px;\"\u003eDimension\u003c\/td\u003e\n\u003ctd style=\"width: 37.5898%; height: 74.8px;\"\u003e\n\u003cp\u003eSingle-layer hydrophilic PP separator: T40 um * W110 mm\u003cem\u003e *\u003c\/em\u003e L10 m (1 roll\/pack)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 33.3219%; height: 74.8px;\"\u003e\n\u003cp\u003eComposite PP\/cellulose separator: T140 um * W110 mm\u003cem\u003e *\u003c\/em\u003e L10 m (1 roll\/pack)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 28.5414%; height: 35.6px;\"\u003e\u003cem\u003eArea Density\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 37.5898%; height: 35.6px;\"\u003e\n\u003cp\u003e~20 g\/m2\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 33.3219%; height: 35.6px;\"\u003e\n\u003cp\u003e~70 g\/m2\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 28.5414%; height: 35.6px;\"\u003e\u003cem\u003ePorosity \u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 37.5898%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e37-48%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 33.3219%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e37-48%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 28.5414%; height: 35.6px;\"\u003e\u003cem\u003ePenetration Strength\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 37.5898%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;4.5 N\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 33.3219%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;4.5 N\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 28.5414%; height: 35.6px;\"\u003e\u003cem\u003eElongation Rate\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 37.5898%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026lt;2%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 33.3219%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026lt;2%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 28.5414%; height: 35.6px;\"\u003e\u003cem\u003eResistivity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 37.5898%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026lt;0.2 Ω cm2\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 33.3219%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026lt;0.2 Ω cm2\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e: \u003c\/span\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\u003cspan\u003e\u003ca href=\"https:\/\/advanced.onlinelibrary.wiley.com\/doi\/abs\/10.1002\/adfm.202407262\"\u003eX.
