Abstract:
The invention relates to a method for the production of flame-proof, expandable styrene polymers (EPS) or flameproof styrene polymer extrusion foams (XPS). According to the invention, an organic bromine compound having a bromine content of at least 70 wt. % and a liquid peroxide, hydroperoxide or a peroxide solution as a flameproof agent is used as a flame-proof synergist.
Abstract:
The invention relates to a method for producing moulded foam elements from pre-foamed foam particles in a mould under pressure, said moulded foam elements having a polymer coating that comprises an amphiphilic or hydrophobic organic compound. The invention also relates to moulded foam elements produced therefrom and their use.

Abstract:
The invention relates to a method for producing foamed moulded bodies from pre-foamed foamed particles which comprise a polymer coating, in a mould, under pressure and in the absence of vapour. The invention also relates to produced foamed moulded bodies and to the use thereof.
Abstract:
The invention relates to a method for producing expandable styrene polymers, which method comprises the following steps: (a) adding an aqueous phase containing a suspension stabilizer and an organic phase containing styrene and initiator to a reactor, (b) starting the addition of a blowing agent at a conversion rate of styrene in the range from 40 to 70% and addition of the blowing agent over a period of 30 to 60 minutes, (c) adding a stabilizer for stabilizing the bead size distribution of the expandable styrene polymer at a conversion rate of styrene in the range from 65 to 99%.
Abstract:

Abstract:
Disclosed are expandable styrol polymer granulates that are rendered flame-proof without using halogen and contain: a) 5 to 50 wt. % of a filler selected among powdered inorganic materials such as talc, chalk, kaolin, aluminum hydroxide, aluminum nitrite, aluminum silicate, barium sulfate, calcium carbonate, titanium dioxide, calcium sulfate, silicic acid, silica flour, aerosil, alumina, or wollastonite; b) 2 to 40 wt. % of expanded granite which has an average particle size ranging from 10 to 1000 µm, c) 0 to 20 wt. % of red phosphorus or an organic or inorganic phosphate, phosphite, or phosphonate; d) 0 to 10 wt. % of black or graphite. Also disclosed are methods for the production of said styrol polymer granulates and the use thereof for producing self-extinguishing expanded polystyrol particles.
