Abstract
An eco friendly radiation cross-linked composition is described that demonstrates excellent resistance to fire and high temperature along with good mechanical properties. The composition which is based on a blend of EVA with a LLDPE, is free of monomer such as vinyl co-agent for radiation cross-linking. The halogen free flame retardant composition is a mixture of 20 to 90% by weight of magnesium hydroxide (powder A) and 90% to 20% of powder B. Preferably the powder B is a double salt of magnesium carbonate and calcium carbonate and the magnesium hydroxide has a specific surface treatment. In addition, 0.5 to 5 parts of flame retardancy agents are selected from talc, zinc borate or molybdate derivative. The chemicals used here reduce toxicity in the environment and do not release toxic chemicals to air and soil during fire. The flame retardant cross-linked polyolefin composition is particularly useful for insulating wires and cables.
