Lithium-Butadiene Rubber (Li-BR)

Trinseo offers low-cis lithium-butadiene rubber (Li-BR) – obtained from anionic polymerization using an organo-lithium initiator – for use in numerous applications.

Low-cis Li-BR is used as an impact modifier in polystyrene and acrylonitrile butadiene styrene (ABS). Li-BR grades from Trinseo are used to toughen polystyrene – creating high impact polystyrene (HIPS) for use in applications such as inner liners of refrigerators, consumer electronics housings, food packaging, and other uses requiring both durability and functionality.

In addition, Li-BR products from Trinseo are applicable in the mass polymerization of ABS copolymers, helping to ensure consistent high quality and an excellent balance between impact strength and gloss.
