Prowaxx™ 1601 FR

ExxonMobil specialties , Mexico

Product Description

Prowaxx 1601 FR is a high melt point, fully refined [FR] paraffin wax that is compositionally engineered to work well in numerous rheological industrial applications such as hot melt adhesives, PVC manufacturing, wax blends and emulsions. Prowaxx 1601 FR can be used in any hot melt adhesives (HMA) formulation and demonstrates exceptional performance in adhesives used for flexible cardboard food containers, specifically fridge and freezer applications.  It is also used in the plastics industry as an anti-slip processing aid, enabling extrusion of PVC. It is a translucent crystalline material in the solid state and a water white, low viscosity, clear liquid when molten. It is derived from petroleum via a carefully controlled refining process yielding a food grade wax with low to no odor. Prowaxx 1601 FR is primarily comprised of straight chain normal paraffin hydrocarbons, which impart excellent gloss and water repellent properties.


The ExxonMobil fully refined waxes, such as Prowaxx 1601 FR, meet the requirements for the Food and Drug Administration (FDA) standards for indirect food contact substances and contain an oxidation inhibitor to improve stability.


Prowaxx 1601 FR is biodegradable under composting conditions according to ASTM D6400 using ASTM D5338.


ExxonMobil waxes are produced and controlled according to the ExxonMobil Product Quality Management System, EN ISO 9000 or equivalent standard.
