(26544-27-4) Diisodecyl pentaerythrityl diphosphite
Product Description
An environmentally friendly and phenol-free pentaerythritol diphosphite antioxidant with high effective phosphorus content can be used as a PVC environmental stabilizer to improve the transparency and temperature resistance of PVC products. It does not contain any free phenol, and no phenolic products are produced during hydrolysis or degradation. It is a completely phenol-free phosphorous acid antioxidant. Added in (un)saturated resins, polyphenol alcohol, epoxy resin and other polymer materials, it can protect the color of the polymer during the synthesis process and improve the thermal stability of the polymer in the later stage.
Suggested addition amount: 0.1–2.0%.
