Expandierbare Polystyrolzusammensetzung, geschäumte Teilchen und Formteile
The present invention relates to a homogeneous composition of an expandable styrene polymer in the form of beads comprising (a) 100 parts b.w. of a styrene polymer having a weight-average molecular mass of 150,000 to 300,000 and a residual monomer content of less than 2,000 ppm, (b) from 2 to 9 part...

| description | The present invention relates to a homogeneous composition of an expandable styrene polymer in the form of beads comprising (a) 100 parts b.w. of a styrene polymer having a weight-average molecular mass of 150,000 to 300,000 and a residual monomer content of less than 2,000 ppm, (b) from 2 to 9 parts by weight of at least one blowing agent comprising n-pentane, (c) from 0.1 to less than 1.0 part by weight of a petroleum wax comprising a mixture of C18 to C80 alkanes, and (d) from 0 to 1.0 part by weight of a nucleating agent chosen from synthetic Fisher-Tropsch or polyolefin waxes. The composition allows the step of pre-expanding the beads to be improved by increasing the rate of expansion of the beads and by improving the productivity of the pre-expansion step, without substantially affecting the final moulding step. |
