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.

Uses

• Industrial Applications z

• Wire & Cable Applications

• Wire Jacketing

Composition

• 40 % By Weight Vinyl Acetate comonomer content

• Thermal Stabilizer: BHT antioxidant

Features

• High Molecular Weight, High Viscosity

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 implyquality, 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.
