Vamac® Ethylene Acrylic Elastomer for Wire and Cable Applications
Halogen-Free and Flame Retardant (HFFR or NHFR) materials are important for applications that require fire safety – Wire & Cable and other molded parts for example, and flooring in the transportation sector.
DuPont™ Vamac® ethylene acrylic elastomer is not inherently resistant to burning. However, when properly compounded, a wire jacket of Vamac® will pass the demanding UL-44 vertical wire flame test, generating very low smoke compared to other flame-resistant materials and provide non-halogen off-gases in fire situations.
DuPont™ Vamac® compounds have proven records in flame retardant applications to provide an excellent characteristic combination of:
Vamac® DP or Ultra DX are usually preferred for HFFR compounds. They provide more stable compound viscosity and better heat aging properties
DuPont™ Vamac® compounds offer low smoke and low toxicity cables applications in a vast array of industries, which include
DuPont™ Vamac® compounds possess extraordinary advantages in both properties and processing.
And especially, for fire related properties they are:
Special grades of Hytrel® thermoplastic polyester elastomer include heat stabilized, flame retardant. Concentrates include black pigments, UV protection additives, heat stabilizers and flame retardants.
