Material Notes:

Description: ENX 7458.00 is a unique broader molecular weight distribution ethylene-butene copolymer that offers excellent flow and impact properties and is ideally suited for plastics modification. Its improved dispersion characteristics make possible the development of high-flow TPO compounds for larger and/or thin walled applications. The polymer has very low crystallinity and is available as surface modified pellets for ease in handling and mixing.Information provided by manufacturer.This former DuPont Dow Elastomers product line is now produced by Dow Chemical.
