LANXESS Butyl rebranded

LANXESS, one of the world’s leading manufacturers of synthetic rubber, has undertaken a complete rebranding of its butyl rubber products.  The new brand family is called X_Butyl. All existing product grades have been renamed, for example: Regular Butyl 301 is now called LANXESS X_Butyl RB 301; Bromobutyl 2030 has become LANXESS X_Butyl BB 2030; and Chlorobutyl 1240 has been renamed to LANXESS X_Butyl CB 1240.

The launch accompanies the new website that features a user friendly design and one-click navigation to access most of the content. It contains a broad range of information on X_Butyl products, developments and applications, as well as an improved customer service portal.

Another step has been the launch of the “LANXESS World of X_Butyl”. This section of the website displays an overview of the new branding and simplified nomenclature. It also shows the interested visitor our geographic setup and the location of relevant contact points. The homepage features relevant and latest information e.g. on the new production facility in Singapore.

LANXESS X_Butyl RB or Regular butyl is a copolymer made of isobutene and small amounts of isoprene and is distinguished by its high impermeability to gas and good resistance to heat, weather and ozone. In addition, it is very resistant to chemicals and demonstrates a high capacity to absorb energy. Alongside its application in tubes, the copolymer is therefore also used in the inner linings of tanks and in conveyor belts.

LANXESS X_Butyl CB is synthetic rubber created by the chlorination of X_Butyl and, compared to regular butyl, is characterized by faster vulcanization times and improved adhesion to other unsaturated polymers. The heat and ozone resistance of the vulcanizates is generally better than those made from regular butyl. Chlorobutyl vulcanizates also demonstrate a stronger resistance to fatigue cracking and a better compression set.

LANXESS X_Butyl BB features properties of vulcanizates made from brominated X_Butyl which are largely identical to those produced from chlorinated X_Butyl. However, vulcanization takes place even more quickly and it is possible to further increase the adhesion to other unsaturated rubbers.
