Dow Nordel® IP 4520 Molded Brake Part
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)
Material Notes:	Nordel® IP 4520 is an amorphous EPDM grade designed for molded applications. It is ideally suited for injection and transfer molded brake parts, corner moldings, general purpose gaskets and moldings. The combination of low viscosity and low crystallinity allows for good processability, low temperature properties and performance without the addition of a plasticizer.
