Features & Benefits
- Product Highlights
- Styrene Butadiene Rubber is made from cold polymerization of styrene and butadiene monomers through low-temperature emulsification polymerization and has similar characteristics to natural rubber.
- It is a general-purpose rubber and is produced in the largest volume of any synthetic rubber.
- SBR 1500 is light-colored and non-staining.
- This is the highest volume general-purpose synthetic rubber.
- It is very weak unless reinforcing fillers are incorporated. With suitable fillers, it is a strong rubber, although not approaching natural rubber or polychloroprene. Otherwise, it has similar chemical and physical properties to natural rubber, with generally better abrasion resistance but poorer fatigue resistance.
- Characteristics
- Good resilience
- Good compression set
- Fair to good heat aging
- Good to excellent abrasion resistance
- Fair tear strength
- Poor flame retardant properties
- Poor weathering characteristics
- Fair oxidation resistance
- Poor ozone resistance
- Poor oil resistance
- Fair to good acid resistance
- Fair to good resistance to alkali substances
