By the way, in general, oil- or chemical-resistant rubber has inferior creep properties compared to water-resistant rubber, and when a great deal of pressure is applied, the rubber elasticity is lost, resulting in poor sealing performance between pressing plates, filter plates, etc. There is a problem that the compression plate and filter plate may be distorted due to uneven pressure at the sealing part. , mainly water-resistant rubber is used.
