KUMHO KHS is manufactured by mixing SBR latex of 23.5wt% styrene content with high styrene resin latex. It is highly resistance to abrasion, flex and tear. It can be loaded with a large amount of filler without deteriorating the physical properties, because it functions as a plasticizer at high temperature during the rubber compounding, such as milling, extruding and calendering.

KUMHO RM21 is a product manufactured by mixing a cold SBR copolymer containing 5.5wt% bound styrene with high styrene resin latex. It is a non-staining masterbatch containing about 21wt% of total styrene. This masterbatch provides the user with an economic advantage through faster and more uniform mixing and improved product quality, and it provides the stiffening effect in the final product.
