Chi Mei Kibipol® LBR PR-255 Low-cis BR rubber
Categories: Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)

Material Notes: Applications: Plastic modification, produce shoe soles, and HIPS modification to obtain high drop impact strength and low gel content.

KIBIPOL® LBR is a low-cis butadiene rubber which catalyzes by the butyllithium catalyst. It has semi-transparent in appearance, low gels, and odorless. It is also easily grafted with SM, so it is suitable for plastic modification. Using low mooney LBR in HIPS manufacturing can reduce the rubber particle size results in high-gloss HIPS.
