Key properties:
Gd-app102 melamine cladding ammonium polyphosphate is gd-app101ammonium polyphosphate modified by melamine on the surface.
1, very low water solubility -gd-app102 has low water solubility that is no more than 0.10g/100mlh2o at 20¦, which makes it useful in application where the product is exposed to high humidity conditions or water.
2, high phosphorus content and nitrogen content-gd-app102 contains 68.0% phosphorus (as p2o5) and 18.0%nitrogen which makes it a very effective fire retardant.
3, low viscosity +c viscosity of gd-app102 is below 20mpa.S.
4, thermal decomposition onset that is above 295¦, which makes it be widely used to plastic with different melt-point temperature.
5, non-halogen-gd-app102 is a highly effective non-halogen fire retardant.
Applications:
Gd-app102 is an effective fire retardant for applications such as:
1, intumescent latex and solvent based paints.
2, polymer systems such as polyethylene, polypropylene, polyurethane, rubbers, acrylics, polyterephthalate.
3, building materials such as wall coverings, ceiling tiles, roofing products, 4, wall panels, wood chip board.
