Polybutene has a superior compatibility in rubber formulations

KEMAT polybutene can be used as an adhesive (plasticiser) for vulcanised elastomers containing both natural and synthetic rubbers for many rubber parts.  PIB enhances performance when compared to mineral and process oils.  It offers good plasticity and adhesion even when small amounts of polybutene are used. When used in rubber compound, polybutene will improve tensile strength, elongation and low temperature flexural properties.

In polypropylene/ethylene-propylene elastomer blends, polybutene modifiers give flexible compounds with good impact strength and processability.  Applications: flexible automotive components; replacement of plasticized PVC in toys, sporting goods and tools.

One of the main benefits of using synthetic rubber in modern industries is its exceptional weathering qualities.  Synthetic rubber is resistant to solvents, oils, oxygen and other chemicals. It ages well.  Also, when exposed to a wide range of temperatures, synthetic rubber doesn’t lose its flexibility.

KEMAT’s portfolio offers the widest range of molecular weights on the market to match any need in formulating rubber parts.
