Q-Prene H 4791 is a Styrene Butadiene Styrene Block Copolymer (SBS Block Copolymer) which has balanced structure of linear and radial block copolymer based on styrene and butadiene with bound styrene of 30% weight. It enhances low temperature flexibility and improves impact property, abrasion resistance and elasticity of thermoplastics in compound formulations. It is used as a modifier of bitumen or thermoplastics and in compound formulations. It is also suitable as an ingredient in formulating compounds for footwear and mechanical rubber goods and may be used in formulating adhesives, asphalt, sealants, inks and coatings.
