{"product_id":"cbebpu","title":"PU (Polyurethane) Powder as Battery Electrode Binder, 100 g\/bottle, CBEBPU","description":"\u003cp\u003ePU (Polyurethane) is rapidly becoming a premier choice for high-performance battery binders, particularly in the fields of flexible electronics, silicon anodes, and solid-state batteries. While most traditional binders (like PVDF) are rigid and brittle, PU is a multi-block copolymer consisting of \"soft segments\" (polyols) and \"hard segments\" (isocyanates). This unique structure allows it to behave like a \"mechanical shock absorber\" inside the battery. The soft segments in PU allow the binder to stretch significantly without breaking, while the hard segments provide the structural memory to pull the particles back together during discharge. The highly polar groups (-NH-COO-) form strong hydrogen bonds with the surface of active materials and the metal current collectors。 \u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 173px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 32.7338%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 67.0863%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCBEBPU (C-BEB-PU)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 11px;\"\u003e\n\u003ctd style=\"width: 32.7338%; height: 11px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 67.0863%; height: 11px;\"\u003e\n\u003cp\u003e9009-54-5\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 32.7338%; height: 35.6px;\"\u003e\u003cem\u003eChemical Formula\/Structure\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 67.0863%; height: 35.6px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg style=\"margin-bottom: 16px; float: none;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CBEBPU_molecular_structure_240x240.png?v=1765911768\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 32.7338%; height: 35.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 67.0863%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eWhite powder\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.7338%;\"\u003e\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 67.0863%;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;99.9%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 32.7338%; height: 19.6px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 67.0863%; height: 19.6px;\"\u003e100 g\/bottle\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\u003eNotes\u003c\/strong\u003e: Please try to store the PU powders in a dry place (glovebox is the best option). \u003c\/span\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:\/\/iopscience.iop.org\/article\/10.1149\/2.0641514jes\/meta\"\u003eN.
