For thirty years, POLYWAX Polyethylenes have served as standard performance additives in a variety of industrial applications, leading to significant performance advantages: Excellent slip and rub resistance in printing inks Improved lubricity and fusing properties in toner formulations Superior performance in controlling set / softening point of hot-melt coatings Through a unique and proprietary polymerization process, the Polymers Division produces the POLYWAX family of low molecular weight ethylene homopolymers, which are 100% linear and saturated and characterized by a molecular weight distribution (Mw/Mn) of approximately 1.1. Because the POLYWAX polyethylenes are linear and have a narrow molecular weight distribution (MWD), physical properties are highly co-related, such that the melting point and hardness are controlled by molecular weight alone. The production process is controllable to the extent that desired molecular weight products are obtained predictably and consistently. Products with number average molecular weights from 450 to 3000, with corresponding melting points of 80°C to 132°C, are commercially produced. Due to their 100% linearity and narrow Molecular Weight Distribution, POLYWAX polyethylenes characteristically display high crystallinity and sharp melting points. High crystallinity Low solubility in solvents Increased hardness at elevated temperatures Oil thickening capability Controlled Mn and narrow MWD Formulating flexibility Low melt viscosity Narrow melting range 100% linearity, fully saturated Resistance to chemical attack Excellent heat stability Most POLYWAX and PETROLITE polyethylenes meet many FDA requirements for food applications. Products are available as prills, and some grades are available as fine particles with diameters from 6 to 150 microns. Linear ethylene homopolymer. Used as an additive to provide slip and rub resistance in printing inks and superior performance in controlling set/softening point of hot-melt coatings. Possesses low molecular weight, full saturation, a narrow molecular weight distribution, high cristallinity and sharp melting point. Offers increased hardness at elevated temperatures, oil thickening capability, formulating flexibility, low melt viscosity, resistance to chemical attack and very good heat stability. Several grades.
