Technical Data
產品說明
DuPont™ Elvax® 40L-03 is an ethylene-vinyl acetate copolymer resin for use in industrial applications.
The melt index is consistent because resin molecular weight distribution is controlled to within a relatively narrow range. The molecular weight is high for this family of copolymers, 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 products.
Because Elvax® 40L-03 is somewhat crystalline, it is free flowing and 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 involving molding, compounding, extrusion, adhesives, sealants, and wax blends. For additional information and properties associated with specific applications, please refer to the Grade Selector Guides found 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 jacketing compounds for automotive ignition and low-smoke cables, and as strippable semiconductive shields for power cables.
• In these applications, the relatively narrow molecular weight distribution and the low gel properties help ensure that compounds will be consistent and finished products will be smooth-surfaced. Smooth, glossy surfaces are desirable because they can imply quality, while uniformity can enhance long-term performance.
• Power cable semiconductive shields made with Elvax®40L-03 also benefit from the consistency of their compounds and low gel content. Any inconsistency in shields can lead to cable failure.
