Rostabil DPDP is a secondary antioxidant in the form of a homogeneous liquid with a characteristic, delicate fragrance. It effectively prevents degradation of polymeric materials, eliminating the effect of yellowing of finished products. Rostabil DPDP stabilizes the polymer processing process, providing effective thermal protection. At the same time, it significantly enhances the color stability of pigment-containing materials and provides transparency to non-pigmented products.
