Synthetic cellular rubber
WebCellular rubber Sponge rubber and cellular rubber are rubber-based materials used mainly for insulation and sealing. Sponge rubber and cellular rubber are made from the same raw materials, namely natural and/or synthetic rubbers, producing different material properties depending on their mixture. WebThe Life Cycle of Rubber. By the late 1930s, the United States was consuming half of the world’s supply of natural rubber. The arrival of World War II led to a natural rubber shortage, which then sparked a shift to create a synthetic substitute. Currently, 70% of rubber used in manufacturing processes is synthetic — a descendant of this ...

Web2 days ago · Nitrile rubber is popular in applications requiring oil resistance, performance under extreme temperatures, and personal protection. Its hot oil resistance makes it a common material in the automotive industry, useful for gaskets, oil seals, o-rings, engine hoses, and other parts. It’s also used to make the rolls in the printing industry that ... WebThe main advantage of NBR over natural rubber is NBR’s ability to trap and retain gas. Synthetic nitrile rubber holds nitrogen bubbles within its structure making it the perfect choice for closed cell sponge applications. Natural rubber allows these bubbles to pass right through the cell wall, making it the weakest material for this use.
