DOW™ DFDA-1648 NT EXP1

A thermoplastic, non-halogen, flame retardant jacketing compound. It is designed for general purpose cable jacket applications. This product provides the following features: - Processing and cabling attributes -- Ease of extrusion, without the need for special screws -- Good anti-scratch whitening -- Good surface appearance (shining and smoothness) -- Good crack resistant on majority of armored cables - Excellent combustion properties (lower smoke, lower acidity) - Excellent electricals -- High volume resistivity (could be used as 0.6/1 kV insulation in dry conditions) -- Low dielectric constant and dissipation factor - Competitive mechanical properties (tensile elongation, tear strength, abrasion resistance, flexibility) - Good thermal properties (low temperature performance, good hot deformation) - Environmentally friendly (lead-free, halogen free, sulfur/antimony-free) - Colorable with EVA based color concentrates Specifications For many cable designs, DFDA-1648 NT EXP1 will meet UL-1685, IEEE-383, CSA FT-4, IEC-60332-3C vertical tray cable burn tests, and IEC-61034 smoke generation tests
