    Abstract: A foamable composition is described that includes at least one base polymer, at least one propellant, at least one lubricant and/or at least one heat stabilizer, and optionally additional additives, selected from crosslinking agents, heat reflectors, heat flow additives, anti-condensation additives, and/or fillers. Corresponding compositions can be processed into polymer foams which can have a heat conductivity of <0.04 E(mK), and an expansion greater than or equal to 1000%, and a weldability of 80 seconds at 240-260° C. Corresponding polymer foams can be advantageously introduced into hollow profiled plastic parts for windows and doors using a coextrusion process and can thus be used to produce door and window frames with low conductivity values.
