When incorporated into polyolefine, it shows high processing stability and no migration. Gd-app104 differs in its mode of action from halogenated flame retardants in the fire. When the polyolefine on exposure to flame, the carbon foam layer formed protects the polymer through its heat insulating effect to reduce further oxygen access and prevent dripping of the polymer. At the same time there are no thrill halogen hydride gases to produce. Applications: Gd-app104, may be mostly used in a range of thermoplastics, especially pp, pe, eva, tpe and rubber etc., which is suitable extrusion and injection moulding applications. Of course it may be suitable for use in hot melt adhesives or coating compounds. Fiber drum, kraft bag, woven pvc bag(polyethylene liner)
