It is a single-layer 25 μm PP separator film produced by a dry stretching process, with stable pore structure, high chemical resistance, and strong thermal integrity. The material is suitable for laboratory testing, coin cell preparation, and battery prototype development. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"1344\" data-end=\"1734\"\u003eThis separator is available in roll and disc formats, making it practical for different cell assembly workflows. The film is described as having excellent anti-oxidation performance, zero transverse shrinkage at 90°C for 1 hour, and properties that help reduce internal short-circuit risk while improving dimensional stability at elevated temperatures. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 data-start=\"1344\" data-end=\"1734\"\u003e\u003cspan class=\"\" data-state=\"closed\"\u003eFeatures\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSingle-layer 25 μm PP separator film. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eSuitable for sodium-ion, potassium-ion, lithium-ion, and lithium-sulfur batteries. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eHigh chemical resistance and thermal stability. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eZero TD shrinkage at 90°C for 1 hour. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eStable pore structure for battery cell assembly. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eAvailable in roll and disc formats for flexible lab use.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable height=\"330\" style=\"width: 98.9837%;
