摘要
Use of a polymer composition comprising (a) 20-80 pts. wt. a polymeric material, based on total weight of components (a) and (b), (b) 20-80 pts. wt polymeric micro-hollow bodies, based on the total weight of components (a) and (b), and optionally (c) additives for filling at least one hollow chamber of a plastic hollow chamber profile, preferably a plastic window profile or a plastic door profile, is claimed. The polymeric micro-hollow bodies comprise a cover made of a polymer and liquid blowing agent present in the cover. Use of a polymer composition comprising (a) 20-80 pts. wt. a polymeric material, based on total weight of components (a) and (b), (b) 20-80 pts. wt polymeric micro-hollow bodies, based on the total weight of components (a) and (b), and optionally (c) additives for filling at least one hollow chamber of a plastic hollow chamber profile, preferably a plastic window profile or a plastic door profile, is claimed. The polymeric micro-hollow bodies comprise a cover made of a polymer and liquid blowing agent present in the cover. The liquid blowing agent exhibits a boiling point below the glass transition temperature of the polymer of polymeric micro-hollow body. The polymeric micro-hollow body is impermeable with respect to the blowing agent in the liquid or gaseous state. An independent claim is also included for the plastic hollow chamber profile, preferablyplastic window profile or plastic door profile, where at least one hollow chamber is foam filled at least partially using the polymer composition.
