As a masterbatch carrier resin for PA6, PA66, PET, PBT, PE, PP, ABS, PC blends and PVC, DuPont™ Elvaloy® AC helps efficiently introduce pigments, fillers and performance additives.
Using Elvaloy® AC masterbatch carrier resin can improve acceptance and dispersion of a wide range of plastics additives and functional fillers such as pigments, flame retardants, slip agents, antiblock, antioxidants, UV stabilizers, antifog agents, antimicrobial, carbon black, TiO2, or blowing agents.
The highly heterogeneous molecular structure of DuPont™ Elvaloy® AC resins make them an ideal masterbatch carrier resin with versatile performance in PA, PET, PBT, PE, PP, ABS, PBT/ABS blends, PC, ABS/PC blends and PVC. The TEM micrographs in Figures 1 and 2 show the compatibility of polybutylene terephthalate (PBT) with Elvaloy® AC versus an alternative ethylene-methyl-acrylate resin from a non-DuPont manufacturing process.
Elvaloy® AC masterbatch carrier resins often can improve compounding efficiency for difficult-to-disperse ingredients. The broad compatibility of Elvaloy® AC with polar and non-polar materials can enhance toughening properties and stress cracking resistance of the final compounds.
Finished compounds can be made with low Elvaloy® AC loading levels for cost savings. The superior thermal stability of Elvaloy® AC resins (especially the EMA copolymers) allows use of higher melt temperatures versus other masterbatch carrier resins, and can help reduce sticking in feed hopper.
DuPont™ Elvaloy® AC masterbatch carrier resins (especially the EBA copolymers) can improve compound low-temperature flexibility.
