Applications

• RIANOX® DLTP-FD decomposes and neutralizes hydroperoxides, formed by auto-oxidation of polymers.
• It is quite often used as a synergist in combination with phenolic antioxidants. It is mainly used in polyethylene, polypropylene, ABS. RIANOX® DLTP-FD has been approved for use in some food packaging applications.
• RIANOX® DLTP-FD used in combination with a primary phenolic antioxidant provides general purpose heat stabilization. With the highest compatibility and lowest melting point of common thio synergists, it is most easily incorporated into the final product. It is most widely used in combination with RIANOX® 1035 for peroxide cross-linked power cables.
• The recommended dosage of RIANOX® DLTP-FD is 0.05-0.5%, the exact addition should be determined in trails.
