Disproportionated Rosin1

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.

Universal Rosin Resin Series RC-80/RC-85/RC-90/RC-100/RC-120

These resins are most popular in domestic and foreign markets. With rosin as basic raw material, it is fabricated through bleaching, esterifiction, stabilization treatment and other processes. RC-80, RC-85, RC-90 and RC-100, characterized by moderate viscosity, light color and good stability, are more cost-effective products and especially applicable to SBS and EVA hot melt adhesives. Good compatibility with EVA is their notable feature. RC-120 and RC-120L, with superior viscosity and good stability, are particularly suitable for high-grade varieties with high requirements on initial and lasting adhesion properties.

Fortified Rosin Resin RC-400 Series (a)

CRUSEL RC-400, RC-415 and RC-425 are a family of rosin resin with superior stability performance. With rosin as basic raw material, they are fabricated through bleaching, esterification, stabilization treatment and other processes. RC-400, RC-415, and RC-425, characterized by moderate viscosity, outstanding heat resistance and oxidation resistance, are particularly suitable for SBS and EVA hot melt adhesives. Good compatibility with EVA is their notable feature.

Fortified Rosin Resin RC-400 Series (b)

CRUSEL RC-430, RC-435, RC-440, RC-445, RC-450, RC-455, RC-480 and RC-488 are a family of pentaerythritols rosin resin with superior stability performance. With rosin as basic raw material, they are fabricated through bleaching, esterification, stabilization treatment and other processes and feature a high viscosity, outstanding heat resistance and oxidation resistance. Users can select products with different softening points on the basis of their needs. The RC-488 is especially suitable for economical SBS and EVA type hot melt adhesive products.

Colorless rosin resin RC-200 Series
