The separator uses a polypropylene outer layer and a polyethylene inner layer, combining structural integrity with a thermal shutdown mechanism for safer cell operation. It is suitable for high-energy cells and research environments where dimensional stability and low internal short-circuit risk are important. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"1200\" data-end=\"1562\"\u003eCompared with single-layer polyolefin separators, this trilayer structure offers a more balanced combination of shutdown behavior, thermal resistance, and mechanical strength. The product is particularly relevant for battery R\u0026amp;D, pouch cell development, cylindrical cell prototyping, and safety-focused separator evaluation.\u003c\/p\u003e\n\u003ch2 data-section-id=\"1ma7m6t\" data-start=\"1564\" data-end=\"1579\"\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePP\/PE\/PP trilayer microporous structure for improved safety and performance. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eThermal shutdown design enabled by the PE inner layer. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eZero TD shrinkage at elevated temperature for better dimensional stability. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eUniform pore structure supports stable ion transport. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eMedium porosity helps balance safety and energy performance. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eSuitable for high-energy lithium battery systems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: center;\"\u003eParameter\u003c\/th\u003e\n\u003cth style=\"text-align: center;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"text-align: center;\"\u003e\n\u003ctd\u003eStructure\u003c\/td\u003e\n\u003ctd\u003ePP \/ PE \/ PP trilayer microporous membrane\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"text-align: center;\"\u003e\n\u003ctd\u003eThickness\u003c\/td\u003e\n\u003ctd\u003e20 μm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"text-align: center;\"\u003e\n\u003ctd\u003eGurley (JIS)\u003c\/td\u003e\n\u003ctd\u003e530 s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"text-align: center;\"\u003e\n\u003ctd\u003ePorosity\u003c\/td\u003e\n\u003ctd\u003e39%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"text-align: center;\"\u003e\n\u003ctd\u003eTD Shrinkage @ 105°C \/ 1 Hour (typical)\u003c\/td\u003e\n\u003ctd\u003e0%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"text-align: center;\"\u003e\n\u003ctd\u003eMD Shrinkage @ 105°C \/ 1 Hour (typical \/ max)\u003c\/td\u003e\n\u003ctd\u003e1.5% \/ 5.0%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"text-align: center;\"\u003e\n\u003ctd\u003eTD Tensile Strength (typical \/ min)\u003c\/td\u003e\n\u003ctd\u003e156 \/ 115 kg\/cm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"text-align: center;\"\u003e\n\u003ctd\u003eMD Tensile Strength (typical \/ min)\u003c\/td\u003e\n\u003ctd\u003e2040 \/ 1500 kg\/cm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003ePuncture Strength (typical \/ min)\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e400 \/ 360 gf\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Flux Battery ","offers":[{"title":"Roll: 100mm*10m (W*L)","offer_id":45475358671039,"sku":"LA031-1","price":39.0,"currency_code":"USD","in_stock":true},{"title":"Roll: 100mm*250m (W*L)","offer_id":45475358703807,"sku":"LA031-2","price":229.0,"currency_code":"USD","in_stock":true},{"title":"Disc: 500 sheets (Dia Φ 18)","offer_id":45475358736575,"sku":"LA031-3","price":39.0,"currency_code":"USD","in_stock":true},{"title":"Disc: 1000 sheets (Dia Φ 18)","offer_id":45475358769343,"sku":"LA031-4","price":69.0,"currency_code":"USD","in_stock":true},{"title":"Disc: 5000 sheets (Dia Φ 18)","offer_id":45475358802111,"sku":"LA031-5","price":279.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/9586\/4767\/files\/SeparatorFilmforSodiumPotassiumLithium-IonLithium-SulfurBatteries1.jpg?v=1775654611","url":"https:\/\/fluxbatteryhub.com\/ko\/products\/pp-pe-pp-trilayer-battery-separator-20um","provider":"Flux Battery ","version":"1.0","type":"link"}
