 HyPerbranched polyphosphate HyPer HPP  

     PRODUCT DESCRIPTION

    Based on nitrogen heterocyclic ring, HyPer HPP are light yellow flame-retardant nitrogen-containing hyperbranched polyphosphate ester resins with heat resistant terminal hydroxyl and own particular properties, such as high molecular weight and high activity, low viscosity and low volatilization. There are three kinds of hyperbranched polyphosphate ester resins HPP-101,HPP-102 and HPP-103 according to their content of hydroxyl-end group and molecular weight. This series of hyperbranched polymers can reinforce and toughen obviously. What’s more ,it is heat resistant and flame-retardant. The patented technology experts identified as "advanced international level".This technology won the 2011 Hubei Science and Technology Progress Award.
