Process for manufacturing composite sheets based on PVC and a network of long fibers, said process comprising the following steps:

Method for producing a PVC-based composite plate and structure including one such plate

A process for manufacturing a plastic-based cellular structure, in which parallel lamellae are continuously extruded through a die having a plurality of parallel slots and upon exiting the die spaces lying between two adjacent lamellae are subjected, in successive alternations and between two sizing units whose length is short enough for the plastic composition to remain molten, to an injection of compressed gas and to a vacuum, the two sides of a given lamella being, in respect of one of them, subjected to the action of the compressed gas and, in respect of the other of them, subjected to the action of the vacuum, and vice versa during the next alternation, so as to deform the lamellae and weld them together in pairs, with formation, in a plane approximately parallel to the extrusion direction, of a cellular structure whose constituent cells extend perpendicular to the extrusion direction.

Process for manufacturing a plastic-based cellular structure and device for implementing this process

Process for manufacturing a plastic-based cellular structure comprising:

Process for manufacturing a plastic-based cellular structure

Process for assembling, by fusion bonding using IR laser radiation, plastic multilayer tapes that comprise an oriented layer that is transparent to the radiation and a layer that absorbs this radiation, the tapes being fusion-bonded using the same technique to a plastic preformed support. Composite tube resulting from the fusion bonding of these tapes to a plastic core.

Assembly process and plastic composite tube

Method for making a hollow body comprising, as sole layer(s), at least one layer L1 consisting of a polyamide composition comprising an aromatic polyamide and an impact modifier, said method comprising extruding the polyamide composition through a die.

Method for making a polyamide hollow body

Plane structure composed of a cohesive assembly of contiguous cellular cells having any cross section and essentially parallel walls from one cell to another, characterized in that the walls of the cells comprise at least two portions based on different polymeric compositions, the junction between said portions being substantially parallel to the plane of the structure.

Plane structure composed of a cohesive assembly of contiguous cellular cells

Hollow bodies made from impact-modified polyamide. Fuel line hoses for both liquid fuel delivery and fuel vapor recovery.

Impact-modified polyamide hollow body

Cartridge for the treatment of a gas by reaction with a reactive substance, comprising a cohesive assembly of alveolate cells that are at least partly filled with the reactive substance, the alveolate cells possessing one part of their wall which is permeable to the gas and impermeable to the reactive substance, said wall part being intended to be in contact with the gas.

Cartridge for treating a gas

Reinforced pipe obtained by winding, onto a tubular support based on a polymeric composition, of reinforcing tapes comprising an oriented polymeric composition in layers crossed at an equal but opposite angle relative to the axis of the pipe. The tapes are selected from those whose polymeric composition exhibits particular mechanical strength properties in tension.

Reinforced plastic pipe and process for manufacturing the said pipe

An extrusion head for the manufacture of tubes including at least one layer of expanded plastic by extruding a stream of molten plastic containing a blowing agent through an annular passage cross section made in the extrusion head. The stream of molten plastic containing the blowing agent spreads out circumferentially and welds itself to itself by the recombining of the two stream fronts. The extrusion head is equipped with a special-purpose thermal regulation device allowing the molten plastic containing the blowing agent to be heated or cooled after the stream fronts have recombined.

Extrusion head for expanded plastic tubes

Process for processing a semicrystalline thermoplastic

The invention relates to an article of which at least one surface zone comprises at least one polyolefin and has been printed by means of a toner by an electrophotographic technique, characterized in that the printed zone contains no toner printing primer and in that the adhesion of the toner to the article is such that it withstands a stripping force of at least 0.4 N/mm exerted by means of an adhesive tape. It also relates to a process for the manufacture thereof.

Articles printed by electrophotography

Process for manufacturing a biodegradable blown film

A process for preparing thermoplastics comprising the steps of cooling an extrudate to a temperature T,, drawing the molten extrudate, relaxing the extrudate at a temperature T,for a duration of at least the average relaxation time of the thermoplastic at the relaxation temperature, and quenching the extrudate to a temperature T,. The process enables the manufacture of films consisting of at least one propylene homopolymer with a thickness of 100 to 250 &mgr;m and having a hot shrinkage of at most 20%, a haze of less than or equal to 3% and a total transparency with respect to air of greater than 70%.

The invention relates to a process for the surface treatment of at least one portion of an article comprising at least one plastic material, the process comprising a step of fluorination for out most 12 seconds, following a step of an energetic surface oxidation of this portion.

Process for the surface treatment of articles comprising at least one
