MEGOLON™ S500

About
MEGOLON™ S500 is a thermoplastic, halogen free, fire retardant cable sheathing compound for general purpose applications. It exhibits good processing characteristics – using a low compression, MEG type screw, processing speeds similar to those of PVC can be achieved. It can also be processed on a simple PVC screw at lower speeds. APPLICATIONS UK: BS 7878: 7 (HD 624.7 S1) Germany: DIN VDE 0207, part 24, type HM2 France: Norme Française NF C 32-323&&
