This disclosure relates to an article (e.g., a vapor-permeable, substantially water-impermeable multilayer article) that includes a nonwoven substrate and a film supported by the nonwoven substrate. The film includes a polyolefin, a nanoclay, and a pore-forming filler.

Blown films based on a blend of a C.sub.2C.sub.3 random copolymer and a C.sub.2-based plastomer, which combine low scaling initiation temperature (SIT), good optical properties and an improved stiffness/impact balance, and which also show an excellent sterilization behaviour.

The invention relates to a process for producing a foam film laminate having at least one compact outer layer and at least one layer composed of extruded foamed polymer bound to the outer layer, wherein the production of the layer of foamed polymer is effected in such a way that a polymer material is admixed with a chemical blowing agent which is solid at room temperature and, during or after the extrusion, is heated up to or above the activation temperature of the blowing agent, in order to obtain the layer of foamed polymer, wherein the processes is characterized in that the polymer material contains 5% to 60% by weight of at least one HMS polyolefin having a in accordance with ISO 20965 (as at 15 Feb. 2005, measurement apparatus type A) of 10.sup.4 to 10.sup.7 Pa s measured at 190° C. within a range of Hencky strain rate of 0.01 s.sup.−1 to 1 s.sup.−1 at a Hencky strain of 3.0. The invention further relates to a polymer composition for the foam layer for performance of the process and to a multilayer polymer film produced by the process and to the use thereof.

A pipe connection comprises a connecting piece, a pipe and a clamping ring. The pipe and the clamping ring are made of a material having memory properties. An end of the pipe and the clamping ring have been reversibly expanded co-jointly and firmly and sealingly shrunk to the connecting piece by back shrinkage. Preferably the clamping ring is made from a cross-linked polyolefin by injection molding.

Disclosed are a water storage tank bladder, a manufacturing method therefor, the water storage tank including the bladder, and a water treatment apparatus including the water storage tank. According to one embodiment of the present invention, the water storage tank bladder used in the water storage tank to receive and store water and discharge the stored water has a lower side of which the thickness can be thicker than the thickness of the upper side of the bladder and thicker than the thickness of the lateral sides of the bladder.

Process for deodorization of recycled polyolefin pellets (23) in three steps: In a first step, the moist pellets (23) are contacted with a circulating inert gas at a temperature between 110° C. and 160° C. in a steam stripper (11), and the steam is precipitated in a condensate trap (29). In a second step, the pellets (23) are sent to a vacuum silo (13) under negative pressure and contacted with a gas flowing in countercurrent. In a third step, after the vacuum silo (13) the pellets (23) are sent to a first heat exchanger (15) and contacted with the gas flowing in countercurrent from the second step.

Nanoporous composite separators are disclosed for use in batteries and capacitors comprising a nanoporous inorganic material and an organic polymer material. The inorganic material may comprise Al.sub.2O.sub.3, AlO(OH) or boehmite, AlN, BN, SiN, ZnO, ZrO.sub.2, SiO.sub.2, or combinations thereof. The nanoporous composite separator may have a porosity of between 35-50%. The average pore size of the nanoporous composite separator may be between 10-90 nm. The separator may be formed by coating a substrate with a dispersion including the inorganic material, organic material, and a solvent. Once dried, the coating may be removed from the substrate, thus forming the nanoporous composite separator. A nanoporous composite separator may provide increased thermal conductivity and dimensional stability at temperatures above 200° C. compared to polyolefin separators.
