Abstract: An extrusion expansion of low molecular weight polyalkylene terephthalates having an IV of below 1.0 dl/g to produce gas-charged beads is disclosed. The process includes an extrusion expanding of the resins and an underwater pelletizing of the melt threads. The obtained beads show a composite structure and are characterized by an IV of 0.69 dl/g or more and a melt viscosity ?0 of higher than 300 Pa·s.

Abstract: This invention relates to expanded polyester materials comprised of polyester/acrylic elastomer blend having an improved ductility and impact resistance, while the compression strength, shear strength/modulus of polyesters remain almost unchanged or unworsened. Addition of a non-reactive/reactive acrylic mixture serving as the blend partner improves the melt strength in an expanding process and leads to a better impact resistance of expanded aromatic polyester materials. All expanded polyester materials are produced with help of a reactive process.

Abstract: The present invention relates to an easy-to-apply, but versatile method for modifying the physical and chemical resistance properties of expanded polyester products, such as fire retardancy and hydrolysis resistance, by melt-modification of the surface layer(s) of said foams and sponges, the manufacturing of such products and the use of such products.

Abstract: The composition and the preparation of a chain-extending concentrate for production of foamed cellular materials of aromatic polyesters is disclosed in this invention. The chain-extending concentrate includes an ethylene-acrylate copolymer, a high-temperature thermoplastic and a multifunctional compound. The preparation process includes two steps: 1) Mixing and melt blending the multifunctional compound and the HT thermoplastic resin into the matrix of the ethylene-acrylate copolymer in an internal mixer and 2) extrusion of the mixture at a temperature below the melting point or reaction temperature of the multifunctional compound.

Abstract: The foam tube for pipe insulations has an external surface and an internal surface. The internal surface is provided with an adhesively bonded layer of fibers. The fibers are a material having a melt temperature that is higher than that of the polymeric foam. The fibers are adhesively bonded to the internal surface such as to stand up from the internal surface. The fibers are substantially uniformly distributed over the internal surface providing a surface coverage of 2 to 20 percent. Further, the fibers have a linear density of 0.5 to 25 dtex and a length of 0.2 to 5 mm. With this fiber layer the polymeric foam tube has an improved thermal resistance and thermal conductivity.
