Buna® CB 550 IT

Buna® CB 550 IT is a Lithium catalysed butadiene rubber with a low 1 ,4-cis content. The product is produced by a solution polymerization process which enables the production of very pure, virtually gel-free, very clear and almost colourless products. The use of organometallic catalysts results in highly uniform polymers that are particularly suited for use in high impact polystyrene (HIPS) and for the mass-solution polymerization of Acrylonitrile-Butadiene-Styrene resins (m-ABS). Buna® CB 550 IT complies with important the food contact regulations.
