- Applications
For any application in contact with copper, the concentration levels range typically between 0.1% and 0.2%. PUREstab MD-1024 is highly effective to prevent the harmful effects of copper conductors in polymers used as primary wire and cable insulation, including polypropylene, high- and low-density polyethylene, and some thermoplastic elastomers. It is also recommended for use other polymer systems where contact with metals may affect polymer properties and stability, including EPDM, peroxide- and radiation-crosslinked polyethylene, polybutene, styrenic polymers, unsaturated elastomers, PVC, PVB and others.
