Powerful Solutions for Electrical Equipment Manufacturers

Momentive products can be found in components throughout the electrical grid providing high quality, consistent insulation and other performance properties.


Our epoxy resins are used in generators, dry-type transformers, switchgear and bushings to protect equipment from the environment and shield the environment from electrical current. Momentive epoxies have been proven over years of service and are known for their consistent quality and performance.


Our silicone elastomers solutions offer a variety of advantages over traditional ceramic materials such as porcelain or glass, in medium and high voltage switchgear applications. Silicone rubber materials are generally lighter, require less maintenance and offer better hydrophobicity and easier processing while delivering outstanding service life and excellent tracking and erosion-resistance.


Typical applications for Momentive silicone-based products include wire and cable, high voltage insulators, EMI shielding, breakers/disconnect switches and surge arrestors.
