Acetylene Black is a modifier for thermal conductivity tires curing bladders used in the rubber tires manufacturing process. It also serves as a modifier for:

• Anti-static compounds for belts and hoses.
• Spark plug cables.
• Conductive rubber rollers.
• Silicone rubber compounds.

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 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.
