    XS-FR-2300/2310(HFFR for TPE elastomer )
    XS-FR-2300/2310 are phosphorus-nitrogen type halogen free flame retardant, Halogen Free Fire Retardant for Thermoplastic Elastomer (TPE), which is designed for TPE (including PP or other carbon resin systems) . The flame retardant mechanism is char-foaming will be happened to stop gas phase combustion. It could be widely used for power cables, communication cables, automotive cables, and etc. The final product has smooth surface, has no PH3 and no precipitation, has good water resistance property and excellent electrical properties.
    XS-FR-2300 is designed for PPO system of TPE and XS-FR-2310 is for non-PPO system.

    During processing, the extrusion temperature should be around 200-220℃ and the screw combination should be moderate intensity, since too hot temperature will make the flame retardant decomposed. The shear heat of the screw is very hot, although the decomposion temperature of XS-FR-2310 is more than 280℃, it still could be decomposed as synergistic effect of heating and shearing.
