Low-current and contact rubber is a functional rubber component used for ON/OFF switching and transmission of electrical signals, or for sealing inside equipment. Conductive rubber, compounded with carbon or metal powder to impart conductivity, or rubber with high insulation properties, is used. Its main applications span a wide range of low-current products, including keypads, switch contacts, waterproof and dustproof gaskets for connectors, and electromagnetic shielding materials, used in home appliances, office automation (OA) equipment, automotive electrical components, and medical devices. Precision molding by compression molding and injection molding is the mainstream processing method, with die-cutting and liquid silicone rubber molding also being employed. This is a field where electrical properties and durability are strictly demanded, typically using silicone rubber or EPDM as a base material.
