SILMASTAB AE1527

SILMASTAB AE1527 by Silma is a highly concentrated synergistic masterbatch of antioxidants and process stabilizers on polyolefinic universal carrier. It is specifically designed for ATH & MDH filled PE & EVA compounds designed for cable applications. It is suitable for halogen-free flame retardant (LSZH or LS0H) compounds containing MDH filler, the natural one (ground brucite) and the synthetic one, in order to avoid any discoloration or color change due to interaction between phenolic antioxidants and MDH. PE/MDH or EVA/MDH compounds with this product will not get green or brown color, as sometimes occurs with traditional antioxidants during compounding or during pre-drying or during cable extrusion. 1% of SILMASTAB AE1527 works also as a viscosity reducer and processing promoter. It should be used at a dosage from 0.5-2% depending on the temperature rate of the final compound, in HFFR recipes. The recommended dosage for 80°C aging temperature is 0.5-1% and for 90°C temperature is 1-1.5%. It has a shelf life of one year.
