Our cold polymerized emulsion-styrene butadiene rubber (E-SBR) of BUNA™ SB Rubber grades use TDAE oil to comply with REACH regulations. These grades provide a good balance of performance and processability with superior quality.
With over 95% cis content, Trinseo’s nickel-butadiene rubber (Ni-BR) is characterized by an adjusted molecular weight that leads to excellent processing behavior. Our BUNA™ Cis 132 Rubber is optimal for tire applications with low hysteresis and good tear resistance.
Trinseo’s S-SBR grades are produced by anionic batch polymerization. They are available in a wide variety of styrene and vinyl contents and are used in manufacturing high-quality tires for heavy trucks.
Our proprietary functionalization technologies effectively improve interaction of the S-SBR polymer with carbon black and silica filler, leading to significantly reduced dynamic heat buildup and rolling resistance.
