Ricon® 157 is a low molecular weight, liquid polybutadiene resin with moderately high vinyl functionality, offering good reactivity, exceptional hydrophobicity, and excellent processing characteristics. Its polymeric structure ensures compatibility with saturated and unsaturated elastomers. As a Type II coagent, it provides good crosslink densities without impacting the cure rate, making it ideal for extrusions and moldings requiring higher crosslink density and improved processing.
