The invention relates to a connection method in addition to a functional part which can be used therefor and to a flame-retardant total system produced in accordance therewith. The invention relates to a method for connecting a single- or multilayer functional part (10) to a third component (20), wherein the functional part (10) has functional elements (14, 16) projecting on at least one side. Said method is characterized in that the functional part (10) is formed at least partially from a material which is at least partially transparent to laser light, and in that a blocking layer (18) is disposed so as to be at least partially opaque to laser light in such a way that after passage of the laser light through the functional part (10) the laser light inside the blocking layer (18) generates heat by absorption which is suitable for melting the functional part (10) and/or the third component (20) in order to connect them to one another in this way.

The present invention relates to compositions comprising at least one thermoplastic polyurethane, at least melamine cyanurate, at least one first phosphorus-containing flame retardant (F1) selected from the group consisting of derivatives of phosphoric acid and derivatives of phosphonic acid and at least one further phosphorus-containing flame retardant (F2) selected from the group consisting of derivatives of phosphinic acid, and to the use of such a composition for production of cable sheaths.

In an embodiment a method of making an article, comprises: forming the article comprising a first portion comprising a polymer composition and a second portion, wherein a composition of the first portion and of the second portion are different; and processing the article at a manufacturing temperature that is greater than a Temperature A, wherein Temperature A is at least one of the heat deflection temperature, the glass transition temperature, the melting temperature, and the degradation temperature; wherein the first portion comprises at least one of (a) the polymer composition in the form of a filled, channeled structure and (b) a phase change material; wherein during the processing, an average temperature of the polymer composition is maintained below Temperature B, wherein Temperature B is at least one of the heat deflection temperature, the melting temperature, the glass transition temperature, and the degradation temperature.

A fuel line comprising a thermoplastic composition is described. The thermoplastic compositions exhibit high strength and flexibility and can be used to form one or more layers of single layer or multi-layer fuel lines. Methods for forming the thermoplastic compositions are also described. Formation methods include dynamic vulcanization of a composition that includes an impact modifier dispersed throughout a polyarylene sulfide. A crosslinking agent is combined with the other components of the composition following dispersal of the impact modifier. 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.

Included is a homogeneous sheet, which excludes polyvinylchloride. The sheet includes a polyurethane, a synthetic rubber blend, and a filler. The synthetic rubber blend may include a pre-mix of a synthetic rubber and white oil.

The present invention relates to a composite material, to a method for the production thereof, and to a fire protection element containing the composite material according to the invention for the protection of passage openings in components in the event of fire, such as building parts, through which conduits are guided. The present invention further relates to the use of the composite material as a fire protection element for sealing passage openings and/or joints in components.

Disclosed is a non-flammable thermal insulating composite substrate for motor vehicles including: a textile component constituted by a layer of needle-sewn non-woven fabric composed of a percentage of pre-oxidized polyacrylonitrile fiber included between 40% and 70%, preferably 58% and of the remaining percentage of polyethylene glycol-terephthalate fiber, the textile component having weight preferably 400 gr/m.sup.2; and a barrier fixed to the textile component using a spreading process, constituted by a thermoplastic resin based on low density polyethylene added with non-halogen flame retardants, the barrier having weight preferably 100 gr/m.sup.2. The composite substrate has the following features: a thickness included between 2 mm and 5 mm, preferably 3.8 mm; a weight included between 300 gr/m.sup.2 and 700 gr/m.sup.2, preferably 500 gr/m.sup.2; odorless; no emission of fumes; dimensionally stable, even at heatstroke, with a maximum variation of 1%; and non-flammability.

System and method for producing plastic products from a recycled plastic mix of unidentified, unclean and unsorted mixed plastic waste comprises the thermal and mechanical processing of the recycled plastic waste using continuous extrusion foaming, two-phase cooling, continuous metering of the pulling strength and automatic adjustment of the pulling speed and extrusion speed.

Polyamide moulding composition in particular for railway applications consisting of: (A) from 50 to 90% by weight of a polyamide matrix consisting of (A1) polyamide 12 and optionally (A2) up to 85% by weight of polyamide elastomer based on polyamide 12; (B) from 7 to 28% by weight of flame retardant consisting of (B1) at least one metal phosphinate, and also optionally (B2) up to 40% of a nitrogen-containing synergist and/or at least one nitrogen- and phosphorus-containing flame retardant; (C) from 3 to 15% by weight of plasticizer; (D) from 0 to 15% by weight polyolefin; (E) from 0 to 10% by weight of additives and/or particulate fillers, with exclusion of fibrous reinforcing materials;

A system for sealing large volumes or gaps includes a flexible envelope that can assume the shape of the volume when filled with a foaming composition that expands the envelope to the boundaries of the volume. The foaming composition may be integral with the envelope or delivered in bulk by an external device. The foaming composition may be one or multiple parts, typically two parts such as a poly isocyanate and a polyols, in which case it is necessary to keep the two parts separate until foaming is desired. Separation may be accomplished by providing multiple compartments that deliver components via a mixing device into the interior. The envelope may include ribs for structural strength and shaping, and leak pores around its perimeter to enhance bonding and sealing. It may also include perforations for bulk, modular seals or for separation of portions of the envelope to seal irregular shapes.
