Abstract:
Disclosed are expandable styrene polymers (EPS) containing, in relation to the styrene polymer, a) 0.05 to 5 percent by weight of an organic bromine compound containing a minimum of 50 percent by weight of bromine as a flameproofing agent, b) 0.05 to 2 percent by weight of a flameproofing synergist, c) 1 to 5 percent by weight of a metallic salt as an acid collector. Also disclosed is a method for producing said expandable styrene polymers.
Abstract:
Expandable styrene polymers (EPS) comprising, in each case based on the styrene polymer, a) from 0.05 to 5% by weight of an organic bromine compound whose bromine content is at least 50% by weight, as flame retardant, b) from 0.05 to 2% by weight of a flame retardant synergist, c) from 0.1 to 5% by weight of a metal salt as acid scavenger, and process for their production.
Abstract:
Expandable styrene polymers comprises 2-50 wt.% of coating comprising (A) 10-99.9 wt.% of a halogen-free flame retardants, and (B) 0.1-90 wt.% of an organic binder. An independent claim is included for a process for preparation of the styrene polymer, comprising providing expandable styrene polymer in a mixing device, providing the organic binder under homogenous agitation, and providing the halogen-free flame retardant to form the coating.
