Electronic Grade Silicone Gel
CAS Number: 63148-62-9
Electronic grade silicone gel is an ultra-soft, lightly cross-linked silicone encapsulant that provides gentle, stress-free protection for delicate semiconductor devices and sensitive electronic assemblies. Its gel-like consistency allows components to flex without delamination, while providing excellent dielectric properties and protection from moisture and contamination. Widely used in automotive power modules, IGBT modules, and sensor packaging.
