{"product_id":"cgpecmtmptma","title":"TMPTMA {Trimethylolpropane Trimethacrylate, \u003e99.0%} as Crosslinking Monomer for Gel Polymer Electrolyte, 50-200 g\/bottle, CGPECMTMPTMA","description":"\u003cp\u003eTrimethylolpropane Trimethacrylate (TMPTMA) is a trifunctional methacrylic monomer (C18H28O6) featuring three reactive methacrylate (CH2=C(CH3COO-) groups radiating from a central trimethylolpropane core. In advanced energy storage research, TMPTMA is widely utilized as a high-performance crosslinking agent for Gel Polymer Electrolytes (GPEs) and in situ polymerized solid\/gel systems, delivering exceptional thermal stability, high crosslink density, and robust mechanical reinforcement for lithium and sodium metal batteries.\u003c\/p\u003e\n\u003cp\u003eThe main functional roles of TMPMA as crosslinking monomer for GPEs are: (1) \u003cstrong\u003eRobust 3D Network \u0026amp; Liquid Immobilization\u003c\/strong\u003e: Upon thermal or UV-initiated free-radical polymerization (using initiators like AIBN, BPO, or photoinitiators), TMPTMA rapidly crosslinks to form a dense polymer mesh that permanently traps and immobilizes organic liquid electrolytes. This converts a free-flowing liquid cell into a dimensionally stable gel without compromising ionic conductivity. (2) \u003cstrong\u003eSuppression of Dendrite Penetration\u003c\/strong\u003e: The high crosslink density and elastic rigidity imparted by TMPTMA's trifunctional nodes create a mechanically robust barrier that resists sharp lithium dendrite propagation during fast-charging cycles, significantly improving safety against internal short circuits. (3) \u003cstrong\u003eEnhanced Cathode Interfacial Compatibility\u003c\/strong\u003e: When used in in situ polymerization protocols, the low-viscosity precursor solution thoroughly infiltrates porous electrodes and separators. Upon curing, it eliminates interfacial resistance gaps and forms a stable passivation layer that mitigates parasitic oxidation at aggressive high-voltage cathode interfaces.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 407.45px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 47.6875px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 47.6875px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 47.6875px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCGPECMTMPTMA (C-GPE-CM-TMPTMA)\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: 28.0576%; height: 35.6px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e3290-92-4\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 155.725px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 155.725px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 155.725px;\"\u003e\n\u003cp\u003eC₁₈H₂₆O₆\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CGPECMTMPTMA_Structure_100x100.jpg?v=1793000120\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.0576%;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%;\"\u003e\n\u003cp\u003eColorless to light amber clear liquid\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 35.6px;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e338.40 g\/mol\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: 28.0576%; height: 35.6px;\"\u003e\u003cem\u003eDensity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003e1.06 g\/mL at 25°C\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 26.0375px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 26.0375px;\"\u003e\u003cem\u003ePackage Size5\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 26.0375px;\"\u003e50 g, 100 g, and 200 g\/bottle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: Please try to store the TMPTMA monomer in a dry place. \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:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S001346861201910X\"\u003eD.
