DuPont Elvax® 40L-03 Ethylene-Vinyl Acetate Copolymer Resin

Elvax® 40L-03 is an ethylene-vinyl acetate copolymer that is useful in many wire and cable applications because of its excellent mechanical, thermal, and low-smoke properties. The melt index is appropriate for convenient compounding and extrusion. The melt index is consistent because resin molecular weight distribution is controlled to within a relatively narrow range. The molecular weight is high, so finished products will be relatively resistant to mechanical damage and elevated temperatures.Compared with other ethylene-vinyl acetate copolymers, Elvax® 40L-03 contains extremely low amounts of gel, or high molecular weight polymer, that can cause undesirable characteristics in finished productsBecause Elvax® 40L-03 is somewhat crystalline, it is free flowing and does not mass during handling.Typical Applications: Jacketing compounds for automotive ignition and low-smoke cablesStrippable semiconductive shields for power cablesFeatures: Narrow molecular weight distribution and low gel properties for consistent and smooth surfaced finished productsStable, long-term cable performanceInformation provided by DuPont.
