{"product_id":"cgpecmtmptmp","title":"TMPTMP {Trimethylolpropane Tris(3-mercaptopropionate), TMPTP or TMPMP, \u003e97%} as Crosslinking Monomer for Gel Polymer Electrolyte, 50-200 g\/bottle, CGPECMTMPTMP","description":"\u003cp\u003eTrimethylolpropane Tris(3-mercaptopropionate) (TMPTMP) is a trifunctional thiol monomer (C12H20O6S3) featuring three reactive thiol (-SH) groups radiating from a central trimethylolpropane core. In advanced energy storage research, TMPTMP is widely utilized as an efficient, trifunctional crosslinking agent for Gel Polymer Electrolytes (GPEs) and in situ polymerized solid\/gel systems via thiol-ene click chemistry, offering a balanced crosslink density, rapid curing kinetics, and robust mechanical elasticity for high-energy lithium and sodium metal batteries.\u003c\/p\u003e\n\u003cp\u003eThe main functional roles of TMPTMP monomer in GEPs are: (1)\u003cstrong\u003e Controlled 3D Network \u0026amp; Liquid Immobilization\u003c\/strong\u003e: When paired with multi-vinyl crosslinkers (e.g., PEGDA or triallyl compounds) in the presence of an initiator, TMPTMP rapidly forms a stable 3D polymer mesh that permanently traps and immobilizes organic liquid electrolytes. This eliminates free-flowing liquid leakage and converts high-energy liquid cells into safe, dimensionally stable gel systems. (2) \u003cstrong\u003eOxygen-Free In Situ Pouch Cell Curing\u003c\/strong\u003e: Standard acrylic or methacrylic in situ polymerizations are frequently hindered by trace residual oxygen trapped inside sealed pouch cells, leading to incomplete conversion. Thiol-ene systems involving TMPTMP are largely immune to oxygen quenching, ensuring uniform, complete crosslinking throughout the entire electrode-separator assembly. (3) \u003cstrong\u003eStress Relaxation During Electrode Volume Fluctuations\u003c\/strong\u003e: The flexible thioether bonds and well-controlled network mesh of TMPTMP-based GPEs provide high elongation and resilience. This enables the electrolyte to dynamically accommodate severe volume expansion and contraction—such as those encountered in silicon anodes or high-capacity lithium\/sodium metal plating—without interfacial delamination or cracking.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 399.05px;\" 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\u003eCGPECMTMPTMP (C-GPE-CM-TMPTMP)\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\u003e33007-83-9\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 111.725px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 111.725px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 111.725px;\"\u003e\n\u003cp\u003e\u003cspan\u003eC\u003c\/span\u003e\u003csub\u003e1\u003c\/sub\u003e\u003csub\u003e5\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e2\u003c\/sub\u003e\u003csub\u003e6\u003c\/sub\u003e\u003cspan\u003eO\u003c\/span\u003e\u003csub\u003e6\u003c\/sub\u003e\u003cspan\u003eS\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CGPECMTMPTMP_structure_160x160.jpg?v=1793058202\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\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\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003eColorless to light-yellow 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\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003e\u0026gt;97%\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\u003e398.56 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\u003e\u003cspan\u003e1.21 g\/mL at 25 °C\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\u003eBoling Point\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e220 °C at 0.3 mmHg\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.0576%;\"\u003e\u003cem\u003eFlash Point\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%;\"\u003e\n\u003cp\u003e\u003cspan\u003e96 °C\u003c\/span\u003e\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 Size\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 TMPTMP\u003c\/span\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003e monomer in a dry, cool and dark place (\u0026lt;15°C).  \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\u003ca href=\"https:\/\/onlinelibrary.wiley.com\/doi\/full\/10.1002\/eem2.70028\"\u003e\u003cspan\u003eM.
