UNIGARD™ RE DFDC-1638 BK

No halogen, flame retardant, thermoplastic sheath material
UNIGARD™RE DFDC-1638 Black is a halogen-free, high flame retardant grade, thermoplastic, low smoke, low corrosion and low toxicity material. This material is used in the field of universal electric sheath. The sheath made with this product can easily pass the IEEE-383/UL-1685 (limited smoke production test) vertical bracket cable combustion test. Of course, the structure of the cable plays an important role in the flame retardant performance. The maximum operating temperature of cables using this material as a sheath can be as high as 90°C.

This product can replace PVC, low-smoke PVC and halogen-containing rubber as sheath materials. It has excellent fire safety (low smoke, low corrosion and low toxicity) and good performance balance. This product can meet or exceed the specifications of many industries for sheath materials: UL-1277 bracket cables, general-purpose communication cables required by UL Subject 444, rail transit applications and various international application fields.

As a halogen-free flame retardant sheath material, DFDC-1638 Black can also be used to replace ordinary non-halogen sheath products. Compared with the existing non-halogen sheath products, the extrusion temperature of this product is higher (up to 392 °F [200°C]), and the common single spiral metering PE screw can be used for extrusion processing.
