DOW™ Electrical & Telecommunications DFDA-1648 NT EXP1 Datasheet,TP, Unspecified,The Dow Chemical Company-SHANGHAI SUSHENG

Message
DFDA-1648 NT EXP1 is a thermoplastic, non-halogen, flame retardant jacketing compound. It is designed for general purpose cable jacket applications. Features DFDA-1648 NT EXP1 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

Extrusion instructions
DFDA-1648 NT EXP1 can be processed on commercial thermoplastic extrusion equipment. Processing practices necessary to achieve optimum characteristics will be dependent on the particular equipment used and can be determined only by extrusion trials.Typical Extrusion Conditions Typical commercial extrusion conditions are shown below as a guide. Each extrusion system is unique and will require optimization of these conditions for the specific unit. EXTRUDER Screw L/D: 20:1 to 24:1 Screw Type: Single Flight Compression Ratio: 2:1 to 3:1 Screenpack: 12 or 20 mesh Draw-Down Ratio (DDR for semi pressure or tube on): Up to 3.5 TEMPERATURE PROFILE BARREL: Feed Zone: 266°F (130°C) Center Zones: 284°F (140°C) Metering Zone: 293°F (145°C) CROSSHEAD: Head: 320°F (160°C) Die: 320°F (160°C) Melt Temperature: < 338°F (170°C) SCREW: Circulating Water: Neutral Compound Drying Drying before extrusion in a dehumidifying hot air dryer for a minimum of 6 hours at 140°F (60°C) is recommended to avoid jacket porosity and to improve the extrusion quality. Do not heat over 195°F (90°C).
