Lanxess rebrands butyl rubber range

ERJ staff report (TP)

Cologne, Germany / Singapore – Lanxess has completely rebranded its butyl rubber products.

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 firm said its new website also comes with one-click navigation to access most of the featured content. It contains a broad range of information on X_Butyl products, developments and applications, as well as an "improved" customer service portal.

Lanxess X_Butyl RB: 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.

Lanxess X_Butyl CB: This synthetic rubber is created by the chlorination of X_Butyl and, compared to regular butyl, is characterised by faster vulcanisation times and "improved" adhesion to other unsaturated polymers.

Lanxess X_Butyl BB: The properties of vulcanisates made from brominated X_Butyl are largely identical to those produced from chlorinated X_Butyl. However, vulcanisation takes place even more quickly and it is possible to further increase the adhesion to other unsaturated rubbers.
