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 is comprised of an ethylene-acrylate copolymer, a high-temperature thermoplastic and a multifunctional compound. The preparation process consists of 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.

Abstract: Manufacturing of polyester based expanded materials made mostly of pre-cleaned and compounded post-consumer polyester by increasing the intrinsic viscosity (IV) during an extrusion process is described. By careful selection of processing conditions and parameters, it is possible to obtain low density polyester foam material with good cellular structure and under stable processing conditions.

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 in this invention. The process is comprised of 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 0.69dl/g or more and a melt viscosity · 0 of higher than 300 Pa.s.

Abstract: The present invention relates to an extrusion line for reactive foam extrusion comprising a primary extruder (1) having a hopper (5) for loading of raw materials into feeding zone of the primary extruder (1), and further comprising a gas injector (7) being arranged in the primary extruder (1), and an extrusion die (9). A side feeding equipment (6a, 12, 16) for loading of reactive additives into the primary extruder (1) is positioned between the feeding zone of the primary extruder 1) and the gas injector (7). The invention further relates to a reactive extrusion process to produce foamed cellular material comprised of a thermoplastic polymer using the above mentioned extrusion line, wherein the thermoplastic polymer is fed into the hopper (5), while reactive additives are loaded into the primary extruder (1) by using a side feeding equipment (6a, 12, 16) located between the feeding zone of the primary extruder (1) and the gas injector (7).
