DuPont^TM Elvaloy® AC Polymer Modifiers Offers Broader compatibility with polar and non-polar resins relative to polyethylene carriers or conventional acrylate copolymer resins > More 'universal' carrier than PE or EVA resins Superior thermal stability relative to EVA resins > Process at higher temperatures than EVA or competitive acrylates Better filler dispersion in substrates > Better color uniformity Enhancement of physical properties > Elvaloy® AC increases impact performance vs. PE-based Masterbatch		Figure 1 Dispersion of Elvaloy® AC (EMA) in PBT Figure 1 Dispersion of Elvaloy® AC (EMA) in PBT
Elvaloy® AC has Broader Compatibility With Polar and Non-Polar Resins DuPont^TM Elvaloy® AC has, due to its very special manufacturing process, a much more heterogeneous molecular architecture which provides a significant compatibility enhancement with almost all other polymers in blends and mixtures. For this reason, Elvaloy® AC is the ideal carrier for masterbatch products. As an example, the TEM micrographs in Figures 1 and 2 show the compatibility of polybutylene terephthalate (PBT) with Elvaloy® AC and a competitive ethylene-methyl acrylate copolymer resin (produced under a different manufacturing process).		This is also an explanation for the property enhancement Elvaloy® AC brings to a variety of polymers and polymer blends such as: Nylon/polyamide (PA) Polybutylene terephthalate (PBT) Polyethylene terephthalate (PET) Acrylonitrile butadiene styrene (ABS) Polypropylene (PP) Polyethylene (PE) PBT/ABS blends ABS/polycarbonate (PC) blends
