Elvax®40L-03
Ethylene Vinyl Acetate Copolymer
DuPont Packaging & Industrial Polymers
产品说明：
DuPont™ Elvax® 40L-03 is an ethylene-vinyl acetate copolymerresin for use in industrial applications.
The melt index is consistent because resin molecular weightdistribution is controlled to within a relatively narrow range. Themolecular weight is high for this family of copolymers, so finishedproducts will be relatively resistant to mechanical damage andelevated temperatures.
Compared with other ethylene/vinyl acetate copolymers, Elvax®40L-03 contains extremely low amounts of gel, orhigh-molecular-weight polymer, that can cause undesirablecharacteristics in finished products.
Because Elvax® 40L-03 is somewhat crystalline, it is free flowingand does not mass during handling.

Applications
Elvax® resins can be used in a variety of applications involvingmolding, compounding, extrusion, adhesives, sealants, and waxblends. For additional information and properties associated withspecific applications, please refer to the Grade Selector Guidesfound on the Elvax® website for industrial applications:http://www2.dupont.com/Elvax/en_US/tech_info/index.html
Elvax®40L-03 is especially well suited for use in jacketingcompounds for automotive ignition and low-smoke cables, and asstrippable semiconductive shields for power cables.
In these applications, the relatively narrow molecular weightdistribution and the low gel properties help ensure that compoundswill be consistent and finished products will be smooth-surfaced.Smooth, glossy surfaces are desirable because they can imply, while uniformity can enhance long-term performance.
Power cable semiconductive shields made with Elvax®40L-03 alsobenefit from the consistency of their compounds and low gelcontent. Any inconsistency in shields can lead to cablefailure.
