High Thermal Conductivity EV Battery Silicone Rubber Potting Compound
High Thermal Conductivity UL 94 V-0 Flame-Retardant Potting Silicone Is Mainly Used for Potting and Encapsulation of Lithium Battery Packs Adhesive Sealant
∎Product Description
●SI8230 is two-component silicone based thermal conductive potting adhesive. It is with Thermally Conductive, two parts, low viscosity potting compound that cures at room temperature to a soft pliable rubber. Will cure in deep sections. Designed to achieve primerless adhesion to many substrates, including metals, plastics, and ceramics.
It has a good fluidity after mixing, can vulcanize to deep layer in room temperature. The operation time can be adjusted according to the temperature. Used to potting protection of varied heat dissipation and temperature resistance components. Fully compliant with RoHS and SVHC REACH standard.
8230 thermally conductive silicone encapsulants can be used in potting applications to dissipate heat away from a component to a suitable heat sink. They also provide protection from harsh environments, vibration and thermal shock. Addition cure silicones provide deep section cure allowing for complete encapsulation for environmental protection whilst maintaining an effective heat path.
∎Application
●Used for encapsulation of various modules, automotive module, LED Power driver modules, Solar panel junction box, EV charging column module, Lithium battery pack, Capacitor banks, Magnetic induction coils, Power inverters, etc.

High thermal conductivity silicone potting sealants are two-part materials filled with ceramic or metal oxides to efficiently transfer heat, protect electronics from environmental damage (moisture, shock, vibration), provide electrical insulation, and offer properties like flexibility, flame resistance (UL 94V-0), and good flow for complex parts, commonly used in LED drivers, power modules, and automotive electronics for heat management.
