Material Notes:
Mineral Flame RetardantUltracarb combines properties normally associated with several different materials that can be used jointly or individually to benefit many applications including rubber, plastics, surface coatings, mastics and sealants. The flame-retardant properties make it a valuable alternative to many of the traditional flame-retardants used in the plastics and rubber industry. The endothermic decomposition absorbs heat and reduces the flame and surface temperature of the burning polymer. The evolution of 53% of the original weight as non-flammable carbon dioxide and water vapor dilutes the oxygen near the burning surface as well as any smoke and flammable gases which are evolved during combustion.The onset of decomposition occurs at 220°C, allowing Ultracarb to be incorporated in high-melt polymers and enables improved compounding rates in intermediate melting point polymers. The fine particle size distribution of Ultracarb yields polymer compounds with good surface finish and improved mechanical properties.The product also offers rheological properties beneficial to the manufacture and practical application of a range of adhesives and sealants, providing a viable alternative to the precipitated calcium carbonates traditionally employed in these systems. In addition to flame retardant and rheological properties, Ultracarb offers a high brightness and neutral whiteness that makes it an ideal extender for titanium dioxide particularly in surface coating applications. Applications: Non-Halogen, Elastomers, Thermoset
