Flame resistant, expandable styrene polymers and foams, and flame retardants |
摘要 |
Flame-resistant, expandable styrene polymers containing a styrene (co)polymer, from 0.4 to 6% by weight of hexabromocyclododecane having a mean particle size of from 1 to 50 mu m, the particles being provided with a firm coating which has a thickness of from 1/100 to 1/10 of the particle diameter and is insoluble in water and styrene, from 1 to 10% by weight of a C3- to C6-hydrocarbon as blowing agent, and, if desired, customary additives, are distinguished by a reduced internal water content and can be processed to form foams which have an improved foam structure and high UV stability.
