Abstract: The present invention relates to an injection moulding process for the preparation of a foamed article with improved surface quality. The present invention further relates to a foamed article obtained or obtainable by the injection moulding process.

Abstract: A foamed part, includes: a long glass fiber filled polymeric material, wherein the long glass fibers have an initial length before molding of the foamed part and a final length after molding of the foamed part; wherein a post-molding length of the long glass fibers in the foamed part is greater than or equal to a post-molding length of long glass fibers in a similarly dimensioned foamed part made without a pressurized plasticizing unit.

Abstract: In various aspects, the disclosure relates to a method of forming a molded article comprising: combining, to form a blend, a polymer base resin and a thermally conductive filler, wherein the thermally conductive filler comprises a platelet filler having a thickness between 100 nm and 10 microns; feeding the blend to a mold cavity of a suitable molding apparatus, wherein the mold cavity has a mold portion that may be retracted in a through-plane direction; foaming the blend to allow a pressure drop; and retracting the mold portion in the through-plane direction to provide the molded article.

Abstract: The disclosure is directed to a solid part, and a device and process of making the solid part. The process includes introducing a glass fiber filled polymeric material to a hopper of an injection molding machine, where the glass fibers have a pre-molding length, melting the glass fiber filled polymeric material to form a melt in a plasticizing unit, pressurizing the plasticizing unit of the injection molding machine with a blowing agent, dissolving the blowing agent into the melt, injecting the melt into a mold cavity up to 100% of volume, and forming the solid part.

Abstract: The invention is directed to a foamed injection moulded article comprising a foam composition obtained by foaming high density polyethylene having a quotient of melt strength and apparent viscosity >2 cN/K·Pa·s wherein the melt strength is determined as described in ISO 16790:2005 and the apparent viscosity is determined as described in ISO 11443:2014.
