SEBS powder for modifying Bitumen
SEBS product with general molecular weight produced by Oretel R&D center with unique technology. It’s technology of polymerization can precisely control the structure of molecular and the distribution of molecular weight so as to produce products with an excellent tensile strength and soft & smooth surface.
This polymer with a wider range of working temperature has a better performance of Compression deformation resistance thus owns a higher bearing capacity of oil and padding in blending modification.
•This polymer with an excellent physical performance, soft and smooth surface as well as a good biocompatibility, is widely used in extrusion and injection products because of its flexible processing methods.
In addition, this polymer contains no halogen or nonylphenol and can be recycled. It is widely used in outdoors application out of its excellent performance of UV-resistance ,Ozone-resistance as well as tenacious ability.
