Product Description
KOMPA Silicone Sheet is a high-performance solid silicone rubber material manufactured from High Consistency Rubber (HCR) technology. Unlike silicone foam materials, this product features a dense and non-cellular structure, providing superior mechanical strength, dimensional stability, electrical insulation, and long-term heat resistance.
Designed for industrial sealing, thermal protection, electrical insulation, and structural applications, KOMPA solid silicone sheets are widely used in EV battery systems, ESS cabinets, electrical equipment, rail transit, industrial machinery, and outdoor environments.
Compared with liquid silicone molded products, solid silicone sheets offer higher production efficiency for sheet and roll materials, easier die-cut processing, and more economical large-area applications.
