An installation () and method for treating composite products () based on thermoplastic material(s) for recycling purposes, the installation at least comprising means () for heating, for reducing size, for crushing and for separating, said means being arranged to form at least one line (') for treating and extracting material(s) to be reused, operating as a continuous or intermittent flow, and regulated if necessary. The installation () is characterised in that the means () for heating and reducing size comprise at least one heated screw mixer, the crushing means comprise at least one roll crusher (′) comprising two rolling rollers (and′) that are heated and set into rotation in opposite directions, the separating means () comprise at least one macroscopic separating means () in the form of a device for discharging macroscopic polluting particles present in the output (′), and the separating means () also comprise at least one microscopic separating means ().

One subject of the present invention is a roofing device () comprising an area support () made up of panels of wood particles on which a vapor barrier first layer (), an insulating second layer () and a third layer () that is impermeable to liquid water are laid. Said device () is one wherein the second layer () is a composite layer formed by the superposition of two distinct homogeneous elementary layers (and'), namely a lower elementary layer () of wood fiber and an upper elementary layer (&#x2032;) made up of a material that is at least partially bio-sourced, that has hygroscopic, antifungal and thermal-insulation properties and that has a low resistance to the diffusion of water vapor.

The invention concerns a method () for recovering and/or recycling a bituminous product by means of pulsed power, the bituminous product comprising bitumen and elements to be separated, involving the following steps:

Method for recovering and/or recycling a bituminous product

The present invention relates to a polymerisable plasticiser formed by a hydrocarbon chain, one end of which bears more than one isocyanate function, said hydrocarbon chain comprising and/or being substituted by an aromatic ring and/or an aliphatic ring and/or said hydrocarbon chain is substituted by at least two hydrocarbon chains that can comprise an unsaturation, and the number of isocyanate functions being strictly greater than 1, preferably greater than 1.2, and, more preferably, grater than 1.5 but less than or equal to 2.2. The invention also relates to liquid polyurethane resin compositions and, in particular, stable, ready-to-use liquid polyurethane resin compositions comprising said plasticiser. The invention further relates to methods for replacing all or part of the exogenous plasticiser and/or solvent in a polyurethane resin by adding said polymerisable plasticiser.

Polymerisable plasticiser, liquid polyurethane resin composition comprising same and uses thereof

Disclosed are granules comprising an elastomeric polyurethane and bitumen, processes for preparing the granules in an extruder and to their use for preparing a bituminous binder, which may especially be used for producing prefabricated sealing membranes by depositing said bituminous binder onto a fibrous support.

Granules comprising bitumen and a thermoplastic polyurethane elastomer, method for its preparation and its uses

The invention relates to polyurethane resin compositions and, in particular, stable, ready-to-use polyurethane resin compositions comprising: a masked polyisocyanate having formula (I), wherein B represents alkyl and A represents a group comprising a number of isocyanate functions of between 1.5 and 2.2, preferably between 1.5 and 2.1 and, more preferably, between 1.5 and 2; or a masked pre-polymer that is the product of a reaction between the above-mentioned masked polyisocyanate and a polyol having between 1.5 and 3 OH functions and a molecular mass of between 900 and 3,000 g/mol, in a ratio such that the number of NCO functions of the masked polyisocyanate in relation to the number of OH functions of the polyol is between 1.5 and 2.5 approximately; or a mixture of the aforementioned masked polyisocyanate and masked pre-polymer. The invention also relates to the use of the masked polyisocyanate in order to form a masked pre-polymer by reacting said masked polyisocyanate on a polyol, and to the use of a masked polyisocyanate and/or a masked pre-polymer in polyurethane resin compositions. 

Masked polyisocyanate and uses thereof

A polyurethane resin composition comprising a prepolymer and a polymerizable plasticizer, and which may also comprise at least one constituent chosen from the group comprising:

Stable, ready-to-use liquid polyurethane resin composition and uses thereof

The invention concerns a hot air device for thermowelding membranes to surfaces. It includes an air inlet, a casing in fluid communication therewith, a combustion chamber mounted within the casing and spaced apart therefrom. The chamber has perforations allowing air to flow therein. The perforations allow some air to flow into the upstream section of the chamber producing an air-fuel mixture, and let the remaining air into the downstream section, thus shortening the flame within the chamber and producing hot air. The device includes an outlet portion for expelling hot air and not allowing a flame out therefrom, and a blower to force airflow from the air inlet through the chamber and out from the nozzle. The chamber may be pyramid or cone shaped and have a deflector to help direct air into the upstream section.
