Synthetic Rubbers




CHIMEI's KIBIPOL® HBR is a high-cis butadiene rubber using neodymium (Nd) as the catalyst. It is colorless and odorless. Compared to NiBR or CoBR , NdBR offers better performance for abrasion resistance, rebound ability and strength. KIBIPOL® HBR also delivers the lowest water content in the world, creating a transparent appearance. This material has gained RoHS and REACH SVHC certifications. KIBIPOL® HBR is the premium materials used globally for different applications, such as tires, shoe soles, and golf balls.

CHIMEI's 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. CHIMEI is one of few suppliers that offers low mooney LBR for high gloss HIPS manufacturing. It can also be used for GPPS modification to obtain HIPS with high falling dart impact strength (FDI). This material conforms to RoHS, REACH SVHC, and the FDA (21CFR177.1640.) standard.



CHIMEI's KIBIPOL® SSBR is a copolymerization of styrene and butadiene, created via a solution polymerization process. Its polydispersity is much narrower than SBR, offers an excellent balance between physical properties and fabricability. It delivers good transparency, processability, smoothness, and dimensional stability with multi-colored, pure white, or transparent designs. It can be used for GPPS modification to obtain HIPS with high drop impact strength (FDI) and low gel content. CHIMEI's KIBIPOL® SSBR’s narrower molecular distribution leads to better physical properties and appearance control. This material conforms to RoHS and REACH SVHC, and meets the banned substance specifications of global shoe brands.



Chimei's thermoplastic rubber is a copolymerization of Styrene, butadiene, and styrene. Its segmented and radial molecular structure allows it to have the same flexible and physical properties of general rubber without the vulcanization process. Its middle segment is similar to rubber and has excellent elastic restoring force, processing flowability, weather resistance, and can be injection molded similar to that of thermoplastics. It can be widely applied for shoe soles, toys, asphalt modifications, mechanical products, plastic modification agents, and adhesive agents.This material conforms to RoHS, REACH SVHC, and the FDA (21CFR177.1640.) standard.



CHIMEI’s KIBITON® Q Resin is a copolymer of styrene and butadiene. This material offers high tortuosity resistance, surface rigidity, and intensity, as well as easy dyeing/printing abilities. CHIMEI’s KIBITON® Q Resin offers especially high transparency, gloss, impact strength, and compatibility with styrenic resins, such as GPPS and SBS, compared to other suppliers’ materials. It can be used in manufacturing general household appliances, clothes hangers, toys, and packaging materials, as well as in polymer modification. KIBITON® Q resin’s tapered microstructure offers better transparency compared to HIPS, and better impact strength compared to GPPS. This material conforms to RoHS, REACH SVHC, the FDA (21CFR177.1640.) standard, and the EU No. 10/2011.FDA (21CFR177.1640.) standard.
