、１５０℃の温度に１時間以上耐えるものが望ましい。The elastomer fiber blended into this has an elongation of 500% or more and an elastic recovery rate of 90 to 99%. Elastomer fibers with an elongation of less than 500% cannot provide the desired large tear strength, and elastic recovery $90% or more.Also, since the elastomer-containing silicone composition is thermally crosslinked to produce a product, a temperature of 150°C is required. It is desirable that the product be able to withstand water for more than 1 hour.
