Solution Styrene-Butadiene Hydrogenated
Styrene-butadiene hydrogenated block copolymers are polymerized in solution and present a fully saturated structure. They are very suitable for high demanding applications such as technical compounding for automotive, medical, toys or food contact applications. They are also used in weather resistance sealants and are very suitable for low temperature applications. Due to their saturated structure they show an excellent thermal resistance as well as superior weatherability (UV light and ozone resistance).
They are FDA and EU regulation food approved materials. These copolymers have a very good oilability, excellent mechanical performance, improved resistance to ageing tests. They can be used for high transparency compounds and are steam sterilisable. They can be available in a wide range of viscosities and in several physical presentations as fluffy crumbs, undusted or dusted with silica and powder form dusted with silica.
