Soltex Acetylene Black and Polybutenes are useful in the rubber and tire industry in a variety of ways.
Acetylene Black is a modifier for thermal conductivity that extends the life and resiliency of the rubber. Common applications are:
- Anti-static compounds for belts and hoses
- Spark plug cables
- Window spacers and sealants
- Conductive rubber rollers
- Silicone rubber compounds
- Tire curing bladders
- Tire tread
Polybutene may be used as a processing aid as well as a plasticizer. The effects on the final product’s physical properties are improved flexibility, impact strength, clarity, and stress crack resistance.
- Polybutene can be used as an extender and plasticizer for vulcanized elastomers
- Natural rubber, butyl rubber, polyisoprene, polybutadiene, ethylene-alpha olefin rubber, and styrene- butadiene rubber (SBR) are examples of systems where polybutene can be incorporated
- Roofing and pipe wraps using butyl rubber or EPDM-modified butyl rubber can be plasticized with polybutene
- Asphalt materials that incorporate thermoplastic block copolymers in roofing materials as well as roofing adhesives can be plasticized with polybutene to increase cold flexibility and adhesion
- Unlike mineral oil or process oils, polybutene cannot be easily extracted from vulcanized elastomers by solvents, heat, or UV exposure and the result is a longer life for the end-product
