Powdered styrene-butadiene rubber is a high polymer elastomer made by polymerizing styrene and butadiene monomers. It can be appropriately modified with other monomers depending on the application. This product features small particle size, narrow distribution, good water resistance, and ease of use. In addition to the conventional characteristics of styrene-butadiene rubber, it also exhibits good compatibility with plastics, asphalt, and paints, rapid bonding, and flexible mixing ratios.
