CEMENT, PORTLAND Resistant O-Rings and Seals
Portland cement is also known as hydraulic cement, and is a key component of concrete. It is used extensively in the building and construction industry, as well as in maritime and civil engineering. Portland cement is a fine powder made by heating limestone and clay in a kiln and then grinding the resulting clinker.
When rubber products are exposed to Portland cement, it can lead to cracking, hardening, and embrittlement of the rubber material. The alkalinity of the cement can cause a reaction with the rubber, leading to swelling and softening. Additionally, Portland cement can cause the rubber to become brittle, leading to cracking and a loss of elasticity. The presence of Portland cement can also lead to discoloration and deterioration of the rubber.
