SYZR Series Expandable Graphite is a high-purity material derived from natural graphite ore, processed to provide exceptional flame retardant properties. With a purity of ≥92%, expansion temperature of 190 ºC, and low smoke emission, this halogen-free graphite is ideal for polyurethanes, coatings, and polymers. Its unique characteristics include non-dripping, reduced heat release, and insulating properties, making it a versatile choice for various applications where flame retardancy is crucial.
Product Specifications
Additional Information
ADT Expandable Graphite is a material based on natural graphite ore. The ore is treated with sulfuric acid in what is called an intercalation process. The material is washed and neutralized to prevent corrosion of metal parts when processed by the user. Excessive shear should be avoided. ADT Expandable Graphite additives may be used in polyurethanes, sealants, coatings, and polymers.ADT Expandable Graphite additives may also be used in conjunction with other flame retardant additives to provide improved flame retardant Properties to a material.This halogen-free flame retardant has a wide range of expansion temperature and can be used for foams, paints, resins, rubber and more.Expandable Graphite is a stratiform graphite and contains acids between each stratums. Once it’s heated, acid generates gas and stratiforms are expanded. This expanded stable structure puts off a fire by cutting off the supply of air. (LOI is 28 by adding 15% in Polypropylene)
Advantages
Can be expanded by heat to make non-flammable stable layerStarting expansion temperature is 150 to 300 CCan be used with other flame retardants such as Zinc Borate or Ammonium PolyphosphateHalogen-freeHeavy metal freeVarious grades with different particle sizes, expansion temperatures and expansion volumes available
Applications
E.G. has been used as non-halogen flame retardant in various applications such asPolyurethane foamEVA foamRoofingNon-flammable paintConstruction materialsSealingsPolyolefin resinThermoplastic resinThermoset resinRubber
