摘要:
The present disclosure provides a metallized polyethylene laminate comprising: an outer polyethylene layer; a metallized acid copolymer layer; an inner polyethylene layer in contact with the metallized acid copolymer layer; and optionally an extruded polyethylene layer; and a sealant layer of polyethylene.
摘要:
Polyarylene sulfide compositions are described that exhibit high strength and flexibility. Methods for forming the polyarylene sulfide compositions are also described. Formation methods include dynamic vulcanization of a polyarylene sulfide composition that includes an impact modifier dispersed throughout the polyarylene sulfide. A crosslinking agent is combined with the other components of the composition following dispersal of the impact modifier throughout the composition. The crosslinking agent reacts with the impact modifier to form crosslinks within and among the polymer chains of the impact modifier. The compositions can exhibit excellent physical characteristics at extreme temperatures and can be used to form, e.g., tubular member such as pipes and hoses and fibers.

A duct (20) includes a polymeric duct wall (22) that circumscribes a fluid-conveyance passage (24). The polymeric duct wall (22) includes, relative to the fluid-conveyance passage (24), an inner surface (22a) and an outer surface (22b). An electrically conductive coating (26) is disposed on at least one of the outer surface (22b) and the inner surface (22a).
摘要:
Provided is a fuel inlet pipe that has a light weight, excellent impact resistance, and causes no fuel leakage. Therefore, the resin-made fuel inlet pipe including at least one resin layer comprising a resin composition containing the following components (A) to (C): (A) a high-density polyethylene (HDPE) or a linear short-chain branched polyethylene (LLDPE); (B) a polyethylene polymerized with a metallocene-based catalyst; and (C) a carbon black. A weight mixing ratio ((A)/(B)) between components (A) and (B) is in a range of from 10/90 to 90/10; a content of component (C) is in a range of from 0.1 to 5 parts by weight with respect to 100 parts by weight of a total of components (A) and (B) ; a soft tissue (Y) comprising the component (B) is inserted between linear crystalline tissues (X) comprising component (A) to expand an interval between the tissues (X); and component (C) is dispersed in the soft tissue (Y).
摘要:
The invention relates to a tube or molded tube element for receiving, storing or guiding air, containing at least a percentage of a chlorine-containing polymer material, and further containing at least one biocidally active component. The invention is characterized in that the polymer material is stabilized by a composition which contains at least one calcium compound.
摘要:
Die vorliegende Erfindung betrifft ein Kunststoffrohr (10) insbesondere für eine grabenlose Verlegung im Erdreich, welches eine strukturierte äußere Oberfläche (13 a) aufweist. Aufgabe der vorliegenden Erfindung ist es ein Kunststoffrohr mit strukturierter äußerer Oberfläche zur Verfügung zu stellen, welches bei der grabenlosen Verlegung im Erdreich eine geringere Reibkraft aufweist als herkömmliche Rohre. Dies wird erfindungsgemäß dadurch gelöst, dass die Mantelschicht (13) des Rohrs an ihrer äußeren Oberfläche Strukturelemente aufweist, die den Reibungskoeffizienten verringern. Dies können beispielsweise muldenartige Vertiefungen (14) oder Dellen sein oder auch Strukturen, die eine Anlehnung in der Natur finden wie zum Beispiel eine Haifischhaut oder Schuppenstrukturen bei Reptilien oder dergleichen.
