Features & Benefits
- Features & Benefits
PUREstab MD1024 is a hindered phenolic antioxidant/metal deactivator used in reducing or preventing the harmful effect of copper or other metals upon various polymers. Widely used in telecommunication wire and cable, provides unmatched extraction resistance and processing stabilization. Can be used alone or with other antioxidants to provide stabilization of polymer in contact with copper, both during processing and long-term service.
Applications & Uses
- Applications
- Compatible Polymers & Resins
- Plastics & Elastomers End Uses
- 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.
