Polyisobutylene (PIB) is a colorless, tasteless, non-toxic thick or semi-solid substance, heat resistance, oxygen resistance, ozone resistance, weather resistance, ultraviolet resistance, acid and alkali resistance and other chemicals good performance. The average molecular weight is 200,000 ~ 87 million. Soluble in benzene and diisobutylene, can be miscible with polyvinyl acetate, wax, etc., insoluble in water, alcohol and other polar solvents. It can make gum sugar have excellent softness at low temperature, and has certain plasticity at high temperature to make up for the shortcomings of polyvinyl acetate when it is cold, hot weather and excessive softening when it meets mouth temperature.
