ULTI-PRO^® 100 processing aid

ULTI-PRO 100 processing aid is a reactive viscosity modifier for difficult-to-process rubber compounds. It lowers the uncured viscosity of the rubber compound, while increasing hardness and dynamic stiffness. ULTI-PRO 100 additive can be used in almost any compound.

As a viscosity modifier, it can be used to replace liquid rubbers, fatty acid (and other) processing aids, and oils, but with an improvement in cured rubber properties. Because of the good cured stiffness it builds, ULTI-PRO 100 additive can also be used as a partial replacement for phenolic-reinforced resins, but without contributing to the green compound boardiness typical with phenolic resin use.
