Prowaxx™ 1531 FR

ExxonMobil specialties , Canada

Product Description

Prowaxx 1531 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 1531 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 1531 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 1531 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 1531 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.

Features and Benefits

*User must check compliance with applicable regulations.

Features	Advantages and Potential Benefits
Narrow high melt point range	Fast set point in HMA formulations Achieve optimal fusion time of the PVC
Highly crystalline structure	Fast set point in HMA formulations
Low oil content	Minimal oil migration Less than 1% oil in wax
Controlled molecular composition and homogenous distribution	Superior adhesion formulation performance in fiber tear at lower temperatures Enables optimal flexibility in processing conditions during PVC extrusion
Lower viscosity	HMA formulations: • Enhances flow onto the substrate and improves surface wetting • Lower adhesive processing time PVC wax formulations: • Allows optimal migration of wax out of PVC matrix to metal surface lubrication • Improved distribution in PVC matrix
Colorless and translucent in solid state	Clarity in HMA formulations does not interfere with package designs
Oxidation resistance	Superior shelf life enables improved product stability
Low to no odor	No cross-odor contamination
Food grade quality	Can be safely used as a component of nonfood articles in contact with food*
Primarily straight chain normal paraffin hydrocarbons	Outstanding water repellent properties Excellent gloss
