Abstract: Extruded closed-cell foam panels produced using a halogen-free blowing agent have a min. thickness of 20 mm and cross-section of at least 50 cm2. They have a thermoplastic matrix based on a styrene polymer and opt. additives which are insol. in the matrix and are free from halogenated gases. The novelty is that the matrix has a Vicat softening temp. VST B 50 (DIN 53460) of at most 100 deg C. and melt index MVR 200/5 (DIN 53735) of at least 5 ml/10 min. The prodn. of the boards by extruding a mixt. of plasticised thermoplastic matrix with 1-15 wt.% halogen-free blowing agent and opt. usual additives is also claimed.
