Abstract
In order to provide a raw material for foam rubber coated gaskets having a stable sealing property in a wide temperature range, a foam rubber layer or a liquid silicone foam rubber layer is formed on one surface of a metal plate, while a liquid silicone foam rubber layer is formed on the other surface thereof. The liquid silicone foam rubber layer is formed between the metal plate and a film. The film is later removed. Resilience after exposure to a high temperature atmosphere increases and a sealing property improves by forming the liquid silicone foam rubber layer in this way.
