Lanxess adds two low-viscosity grades to HNBR range

Leverkusen - Lanxess has added two products to its low-viscosity Therban AT line, bringing the number of grades available in the " Advanced Technology" range of HNBR materials to three. The new grades are:

• Therban AT C 3443 VP (34% ACN/3.5% RDB/Mooney 39)
• Theban® AT A 3904 VP (39% ACN/

The first AT grade released was Therban AT VP KA 8966 (34% ACN/

Accorsding to a Lanxess press release, "the low viscosity coupled with a narrow molecular weight distribution provide substantial advantages such as easier mixing, faster throughput, better surface quality, lower plasticizer levels, reduced mould fouling and the option to apply higher filler loads."

Typical applications for Therban -based compounds include large complex shapes such as stators or blowout preventors for the oil well industry, injection moulded seals, extruded hoses, rubber rollers for paper processing, and wire & cable.
