produces various grades of Solution-Styrene Butadiene Rubber (S-SBR) under the BUNA\u00ae brand. S-SBR is a copolymer of styrene and 1,3-butadiene produced through a solution polymerization process in hydrocarbon solvents. S-SBR is one of the main raw materials used in the production of high-performance tires, especially those requiring low rolling resistance, excellent wet grip, and high durability typically used in the high-performance automotive sector.<\/p>\n

LOW VINYL SOLUTION STYRENE-BUTADIENE RUBBER (BUNA\u00ae SL)<\/h2>\n

A low vinyl content results in a lower glass transition temperature (Tg), providing high flexibility, superior abrasion resistance, and low rolling resistance. BUNA\u00ae SL is commonly used in tire manufacturing and technical rubber products made through extrusion processes.[\/et_pb_text][et_pb_text ul_position=”inside” _builder_version=”4.27.4″ _module_preset=”default” ul_line_height=”2em” hover_enabled=”0″ global_colors_info=”{}” theme_builder_area=”post_content” sticky_enabled=”0″]<\/p>\n

SOLUTION STYRENE-BUTADIENE RUBBER BLOCK POLYMER (BUNA\u00ae BL)<\/h2>\n

contains a block styrene structure, making it ideal for producing rubber products that require higher strength and hardness without compromising abrasion resistance.[\/et_pb_text][et_pb_text ul_position=”inside” _builder_version=”4.27.4″ _module_preset=”default” ul_line_height=”2em” hover_enabled=”0″ global_colors_info=”{}” theme_builder_area=”post_content” sticky_enabled=”0″]<\/p>\n

SOLUTION VINYL STYRENE-BUTADIENE RUBBER (BUNA\u00ae VSL)<\/h2>\n

has a modified molecular microstructure with a higher vinyl content, which increases Tg to enhance traction and wet grip while maintaining flexibility and low rolling resistance. This makes BUNA\u00ae VSL especially suitable for premium tire formulations and other high-performance rubber applications.[\/et_pb_text][et_pb_text ul_position=”inside” _builder_version=”4.27.4″ _module_preset=”default” ul_line_height=”2em” hover_enabled=”0″ global_colors_info=”{}” theme_builder_area=”post_content” sticky_enabled=”0″]<\/p>\n

FUNCTIONALIZED SOLUTION VINYL STYRENE-BUTADIENE RUBBER (BUNA\u00ae FX)<\/h2>\n

BUNA\u00ae FX is a high-performance grade of Solution-Styrene Butadiene Rubber (S-SBR) that has been chemically functionalized with polar end-groups to improve silica filler interaction. This significantly enhances wet grip performance and overall tire handling efficiency.[\/et_pb_text][et_pb_text module_class=”tbl_tablepress” _builder_version=”4.27.4″ _module_preset=”default” overflow-x=”scroll” global_colors_info=”{}” theme_builder_area=”post_content”]<\/p>\n\n\n\n\n\t\n\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t
