Product type
Styrene Butadiene Rubber (SBR) is a synthetic rubber made from the polymerization of styrene and butadiene. It is known for its excellent abrasion resistance, flexibility, and aging stability, which makes it a popular choice in various industrial applications. SBR is typically produced in two forms: emulsion and solution, each offering different properties suited to specific uses.
| Hardness range | Shore A 30 to 80 |
| Tensile strength | 5 to 25 MPa |
| Elongation at break | 300% to 800% |
| Temperature range | -50°C to 100°C |
| Color | Black or colored formulations available |
When selecting SBR, consider the specific application requirements such as hardness, tensile strength, and temperature resistance. It is also important to specify the desired form (emulsion or solution) and any color preferences. For quotes, provide information on the quantity needed and any specific grades or certifications relevant to your industry.
