ULTRA-PEP

ULTRA-PEP™ 90 is a multi functional processing additive. ULTRA-PEP™ 90 works as a mild mastication agent in the early stage of NR compounding and subsequently aids filler dispersion and down line processing, like extrusion and mold flow. Since the mastication effect is slower than with common peptizing agents, fewer break downs of polymer chains can be observed, resulting in better physical and dynamic properties. ULTRA-PEP™ 90 can be added in the masterbatch compound with other compounding ingredients and therefore a pre-mastication step is not needed. As such, additional cost saving could be achieved.

ULTRA-PEP™ 96 is a combined peptizing and processing additive for natural rubber. ULTRA-PEP™ 96 is easily dispersed in rubber due to its content of dispersing agent present. ULTRA-PEP™ 96 is extremely active and therefore can be used at low dosage levels. Its peptizing action starts at 90 °C but reaches an optimum at 140°C.

ULTRA-PEP™ 148 is a chemical peptizer for natural rubber based on DBD and extremely effective at low dosage levels. ULTRA-PEP™ 148 is environmental friendly owing to its completely dust free appearance. The low melting point of the carrier ensures a fast, easy incorporation, even at lower mastication temperatures.
