How Additives Improve SBR Properties?
SBR can be modified to enhance its properties. One common method is through incorporating additives into the SBR during the mixing process. Some of the additives include:
- Fillers (e.g., carbon black, silica): Enhance tensile strength, abrasion resistance, and tear strength.
- Plasticizers (e.g., oils, resins): Improve flexibility and reduce stiffness.
- Antioxidants: Prevent degradation caused by exposure to oxygen and heat, thereby extending the service life of SBR products.
- Antiozonants: Protect against cracking and deterioration caused by ozone exposure, particularly in outdoor applications.
- Flame retardants: Reduce flammability and improve fire resistance in applications where fire safety is a concern.

Is SBR material recyclable?
Yes, SBR material is recyclable. It can be reclaimed, ground down, and reused in various applications.
Is SBR material suitable for sealing applications?
Yes, SBR (Styrene Butadiene Rubber) material is suitable for sealing applications due to its ability to conform to irregular surfaces and provide effective sealing against liquids, gases, and other environmental elements.
Can SBR be used in food-contact applications?
No, SBR (Styrene Butadiene Rubber) is generally not recommended for use in food-contact applications. SBR may leach harmful chemicals or impart undesirable flavors or odors to food products, making it unsuitable for direct contact with consumable items.
