LOW-CIS BR
Low-Cis Polybutadiene Rubber (Low-cis BR)
Butadiene elastomers are characterized by an excellent resistance to abrasion, good resistance to fatigue cracking and
crack growth. Their extremely low glass transition temperature provides enhanced low temperature performance
compared to other general-purpose rubbers.
LVE Intene® low-cis polybutadienes are produced by solution polymerization in an aliphatic solvent, thus greatly
improving the environmental friendliness of the whole process.
All Intene® grades are produced by a continuous process using a Lithium-based catalyst system determining the (micro)
structure of the final product.
In the case of the grade Intene® K C30AF, a coupling agent is used to obtain a star-branched structure.
Low-cis BR (both linear and branched) has become the product of choice for the industrial modification of plastics in
High Impact Polystyrene (HIPS) or Acrylonitrile-Butadiene-Styrene (ABS) and it is also widely used for all types of tyres
