DuPont™ Elvax® 40L-08 Ethylene-Vinyl Acetate Copolymer Resin

 

Subcategory: Ethylene Vinyl Acetate; Thermoplastic

Material Notes:
Elvax® 40L-08 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-08 contains extremely low amounts of gel, or high molecular weight polymer, that can cause undesirable characteristics in finished products

Because Elvax® 40L-08 is somewhat crystalline, it is free flowing and does not mass during handling.

Typical Applications:

  • Jacketing compounds for automotive ignition and low-smoke cables
  • Strippable semiconductive shields for power cables

Features:

  • Narrow molecular weight distribution and low gel properties for consistent and smooth surfaced finished products
  • Stable, long-term cable performance
