- Kumho KBR-710S and KBR-710H are solution low-cis polybutadiene rubber (LBR) produced with alkyllithium catalyst based. - They have 34.5% of cis content and 14.5% of vinyl content. - They are used as a base polymer in production of HIPS (High Impact Polystyrene), which is the main material applied to the manufacture of cabinets for home appliences, interior goods, toys, and everyday goods due to their excellent elasticity and vinyl content giving good reactivity. Characteristics and Applications - When melted in styrene at 5% concentration, it is transformed into a bright color with the tone of APHA color 5. - Very low gel content (Max 0.02%) - Typical applications are HIPS, motorcycle tires, footwears, and general mechanical products.
