Applications
Antioxidant DLTP has the function of decomposing hydroperoxide. DLTP is suitable for long-term thermo-oxidative aging protection of resin. DLTP is widely used in PE, PP, PVC, ABS, rubber, etc. DLTP does not pollute, does not color, and has good compatibility with resin. DLTP can significantly change the heat resistance and oxidation resistance characteristics of products. DLTP has a good synergistic effect when used together with phenolic antioxidants (such as antioxidants 1010, 1076, 1098, 179, 245, etc.) and ultraviolet absorbers. DLTP has low toxicity and can also be used in food packaging materials.
Storage
Antioxidant DLTP is stable in nature and has no special requirements; pay attention to moisture-proof and avoid high temperature.
