Material Notes:

Description: This crystalline ethylene-propylene-diene terpolymer (EPDM) has a low viscosity for excellent flow characteristics and hot green strength. It has been designed for property modification of thermoset rubber and thermoplastic polyolefin compounds including polyethylene and polypropylene. It can be crosslinked via traditional techniques including sulfur, phenolic, peroxide, irradiation and hydrosilation. NDR 4820P is developmental and made via INSITE™ technology.Information provided by manufacturer.This former DuPont Dow Elastomers product line is now produced by Dow Chemical.
