Foreverest™ SSBR1027 is a food grade SSBR. Which is produced by hexane solution, the solution copolymerization of butadiene and styrene. Using butyllithium as catalyst, the solvents and volatiles are removed by hot water, dewaterer and expander.

It is an equivalent of PLIOGUM® 1027. Which used in bubble/chewing gum base and food contact.
