EXPANSIBLE BEADS OF POLYAMIDE

摘要

The invention relates to expandable granules, containing A) a polymer matrix consisting of A1) at least 55 wt % of polyamide (based on the sum of components A1) and A2)) having crystallinity of up to 30%, optionally a melting temperature in the range of 100 to 340ºC, and a glass transition temperature in the range of 0 to 150ºC, and A2) 0 to 45 wt % of one or more thermoplastic polymers different from component A1); B) a physical blowing agent component and optionally further additives, wherein said expandable granules are suitable for producing a particulate foam for use in the automotive industry, aviation industry, building industry, packaging industry, sports and recreation industry, in transportation and/or in construction.
