The present invention relates to an insulation body based a hard, fine-cell and open-cell polyurethane/polyisocyanurate foam with a barrier film, and a method for producing same.

A method of forming a shaped foamed polymer article and articles obtained from said method.

In one embodiment, a method of forming an extruded board includes mixing a resin and a foaming agent, melting the mixed resin and foaming agent to form a uniformly colored extrudate, differentially expanding voids formed from the foaming agent within the uniformly colored extrudate by passing the uniformly colored extrudate through a breaker plate, forming a board with the differentially expanded voids and uniformly colored extrudate, and forming lightened portions on an outermost surface of the formed board.

A method for producing a molded part, in particular a component of a sporting good, includes providing a mixture of a polymer melt and a foaming agent and injecting the mixture into a mold. The method includes solidifying at least a first portion of the molded part without foaming and at least a second portion of the molded part after foaming inside the mold, wherein the mixture includes a polymer having an average molecular mass corresponding to a viscosity number ≥130 ml/g, preferably ≥170 ml/g, more preferably ≥190 ml/g and most preferably ≥225 ml/g, wherein the viscosity number is determined via solution viscometry according to the ISO 307 standard.
