SBR Rubber Manufacturing
Styrene Butadiene, SBR, Buna-S™ is a copolymer of styrene and butadiene that exhibits good physical properties. SBR was introduced as a replacement to natural rubber during World War II and has some similar performance characteristics and can be used as a substitute when fewer dynamic properties are required. It is a lower-cost material.
SBR has excellent low-temperature flexible rubber parts and good heat resistance and heat-aging characteristics. It also has excellent abrasion resistance and adhesion to metals.

Buna 'S" (SBR)
Vip Rubber and Plastic is one of the best rubber and plastic manufacturing facilities in America. We specialize in custom rubber extrusions, plastic extrusions, rubber sheet products, molded rubber products, plastic pipe and tubing.
Common SBR Uses
SBR is used extensively for tires and conveyor belts but also has many uses in parts as a natural rubber substitute. It is used for custom molded plumbing parts, rubber seals, rubber pads, panel grommets, and gaskets. It is also used in parts such as:
- Seals
- Sleeves
- O-Rings
- Tubes
- Belting
- Wire and Cable
SBR is available from Vip Rubber and Plastic extruded as solid rubber, extruded as closed sponge cell as well as molded and in sheet
