Disproportionated rosin takes gum rosin as base material. Noble metal catalyst raises disproportionation reaction under high temperature and then gum rosin is modified into final products. Light color, high purity and good transparency are the significant features of our disproportionated rosin,our products are especially suitable for demands of high-grade products in the downstream industries. We promise to provide specialized customization production according to the technological requirements of downstream users.
