Material Notes:
Solution Styrene Butadiene Rubber (S-SBR)Characteristics: This product is made by solution polymerization under which styrene and butadiene react in organic solvent using alkyl-lithium catalyst. It is superior to SBR, which is made by emulsion polymerization, in processability, visco-elasticity and low temperature properties. Also, the products' properties can be adjusted to the purpose of consumption according to the proper proportion of styrene content, the micro structure and the molecular weight.Applications: Shoes, Soles, Tires, Machine Parts, Energy-saving Tires, High-efficiency TiresAdditional Notes: Bound Styrene: 23.7%cis-1,4 Contents: 25%trans-1,4 Contents: 39%Vinyl Contents: 39%Dynamic Test: GABO Qualimeter (11Hz)(TAN) 0°C: 0.32610°C: 0.21460°C: 0.12570°C: 0.116This product is so sensitive to sunlight and humidity that it can be tarnished and caused deterioration of quality if exposed. It is recommended to store it in cool and shady area lest it should be exposed to direct sunlight. Do not expose to incompatible materials or contaminants.Data provided by Korea Kumho Petrochemical Co., Ltd.
