{"product_id":"cabshsppca273","title":"Hydrophilic Surfactant Coated PP (Polypropylene, Celgard A273) Disk or Roll as Aqueous Battery Separator, CABSHSPPCA273","description":"\u003cp\u003eCelgard® A273 is a specialized, hydrophilic surface-modified microporous polypropylene (PP) monolayer separator engineered for rapid wet-out and low interfacial resistance in aqueous, alkaline, and highly polar electrolyte systems. Standard polyolefin battery membranes are inherently hydrophobic, but Celgard A273 incorporates a proprietary surfactant surface treatment across its open pore structure to enable immediate, spontaneous electrolyte absorption without requiring alcohol pre-treatment or prolonged vacuum soaking.\u003c\/p\u003e\n\u003cp\u003eThe core advantages of the Celgard A273 separator are: (1) \u003cstrong\u003eImmediate Spontaneous Wetting\u003c\/strong\u003e: Drastically reduces electrolyte filling time and eliminates dry spots during assembly with high-surface-tension electrolytes (e.g., concentrated KOH, aqueous zinc salts, or ionic liquid blends). (2) \u003cstrong\u003eLow Area-Specific Resistance (ASR)\u003c\/strong\u003e: High open porosity and uniform nano-channel distribution provide low ionic transport resistance, supporting high discharge rates and low polarization. (3) \u003cstrong\u003eChemical \u0026amp; Alkaline Resilience\u003c\/strong\u003e: Retains the high chemical resistance of isotactic polypropylene against strong bases, mild acids, and oxidative decomposition at ambient to moderate temperatures. (4) \u003cstrong\u003eDimensional Stability (Zero TD Shrinkage)\u003c\/strong\u003e: Produced via Celgard's dry-stretch process, exhibiting zero transverse shrinkage under elevated operating temperatures to prevent electrode edge exposure and internal short circuits.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 201.2px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 32.9886%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.6904%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCABSHSPPCA273 (C-ABS-HSPP-CA273)\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: 32.9886%; height: 35.6px;\"\u003e\u003cem\u003eMaterial\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.6904%; height: 35.6px;\"\u003e\n\u003cp\u003ePP (Polypropylene) with hydrophilic surfactant coating\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.9886%;\"\u003e\u003cem\u003eThickness\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.6904%;\"\u003e\n\u003cp\u003eT=16 um\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 106.8px;\"\u003e\n\u003ctd style=\"width: 32.9886%; height: 106.8px;\"\u003eDimension\u003c\/td\u003e\n\u003ctd style=\"width: 66.6904%; height: 106.8px;\"\u003e\n\u003cp\u003e(1) Round Disk: D=16 mm (100 pcs\/pack)\u003c\/p\u003e\n\u003cp\u003e(2) Round Disk: D=19 mm (100 pcs\/pack)\u003c\/p\u003e\n\u003cp\u003e(3) Roll: W60 mm\u003cem\u003e *\u003c\/em\u003e L20 m (1 roll\/pack)\u003c\/p\u003e\n\u003cp\u003e(4) Roll: W60 mm\u003cem\u003e *\u003c\/em\u003e L100 m (1 roll\/pack)\u003c\/p\u003e\n\u003cp\u003e(5) Roll: W85 mm\u003cem\u003e *\u003c\/em\u003e L20 m (1 roll\/pack)\u003c\/p\u003e\n\u003cp\u003e(6) Roll: W85 mm\u003cem\u003e *\u003c\/em\u003e L100 m (1 roll\/pack)\u003c\/p\u003e\n\u003cp\u003e(\u003cspan style=\"color: rgb(255, 42, 0);\"\u003eRoll with other width and length can be supplied upon request\u003c\/span\u003e)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 23.2px;\"\u003e\n\u003ctd style=\"width: 32.9886%; height: 23.2px;\"\u003e\u003cem\u003eGurley Value\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.6904%; height: 23.2px;\"\u003e\n\u003cp\u003e345\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.9886%;\"\u003e\u003cem\u003ePorosity \u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.6904%;\"\u003e\n\u003cp\u003e\u003cspan\u003e40%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.9886%;\"\u003e\u003cem\u003ePuncture Strength\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.6904%;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;300 gf\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.9886%;\"\u003e\u003cem\u003eWettability (max- internal)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.6904%;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026lt;30 seconds\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:\/\/onlinelibrary.wiley.com\/doi\/abs\/10.1002\/app.40543\"\u003eD.
