SBR & SCR Neoprene Sponge, Styrene Butadiene Rubber Sponge - Supplier

"SBR Neoprene" scientific name "Styrene Butadiene Rubber", is an elastomeric synthetic rubber produced by styrene and butadiene polymerization based on petroleum. It was invented by Walter Bock of IG Farben AG in the 1930s. The initial design It is used to replace natural rubber to make tires.

In the 1950s and 1960s, companies in the United States and Japan began to use chloroprene rubber to make wetsuits. Later, South Korea, Taiwan, and China also joined the ranks. The chloroprene rubber used to make wetsuits is in the form of closed-cell foam (honeycomb structure), which can be processed to the required thickness and placed between other fabric sheets (such as polyester, nylon, spandex, etc.).

Based on cost considerations, at the end of the 20th century, styrene butadiene rubber began to be used to make wetsuits, also in the form of closed-cell foam (honeycomb structure), commonly referred to as SBR in the industry, and used to replace chloroprene rubber in some applications. The cost of styrene butadiene rubber sponge is significantly lower than that of chloroprene rubber sponge, but its performance is also far behind that of chloroprene rubber sponge. Later, in order to achieve a balance between cost and performance, a mixture of styrene butadiene rubber and chloroprene rubber was developed, which is usually called SCR in the industry.
