REVAC® 18343 is a maleic anhydride grafted linear low-density polyethylene. • OREVAC® 18343 has been designed to develop a reliable bonding strength between polyethylene or ethylene copolymers and mineral fillers such as aluminum trihydrate (ATH) or magnesium hydroxide (MDH). It is an effective coupling agent for halogenfree flame retardant (HFFR) compounds using high loadings of mineral fillers, such as compounds for insulation and sheathing of wires and cables.
