Definitions

  • a drawback of for instance the reel known from the above stated US patent No. 4,702,429 is that the fixed parts of this reel consist of various different materials, viz. cardboard and plastics, wherein only the variable core is made from an EPS foam.
  • a sufficient fusion can be achieved under mild process conditions when particulate expandable polylactic acid is provided with a coating.
  • the foamed moulded part can be obtained with two different methods. Either the particulate expandable polylactic acid is coated and then foamed in one step and formed into a foamed moulded part, or the particulate expandable polylactic acid is first pre-foamed, then coated and subsequently formed into the foamed moulded part.
  • the coating can thus be applied directly onto the particles of polylactic acid or onto already pre-foamed particles of polylactic acid. After the coating has been applied a blowing agent has to be added to the particles in order to make them expandable (again).
  • a 3-D filament reel as referred to in Example 2 was manufactured using a composition of a foam of 20% PLA and 80% PBAT. Said composition was impregnated with 9% CO2 and then expanded to 55 g/l and subsequently shaped into a 3-D reel at a shaping temperature of 90°C in order to obtain a 60 g/l 3-D reel.
