This invention relates to a biodegradable polymer composition which is particularly suitable for use in the manufacture of articles having a high heat deflection temperature (HDT) by injection moulding and thermoforming.

What is described is a method for manufacturing a profile element for sealing building-structure joints, especially for sealing against sound and smoke and optionally against fire, to an apparatus for manufacturing such a profile element and to the use of the profile element manufactured according to the invention for the acoustic, smokeproof and/or fireproof sealing of connecting joints in drywalls, especially of expansion joints. In particular, an improved method is described for continuous and endless manufacture of such a profile element.

The disclosed thermoplastic molding material includes a specific combination of at least three flame retardant additives in addition to at least one thermoplastic polyamide and glass fibers. In some embodiments, the present invention has for its object the provision of specific mixtures of flame retardant input materials which result in glass fiber reinforced polyamide molding materials which pass not only the UL 94 requirements but also the glow wire test in its various forms and can also be processed without discoloration.

The present disclosure provides a plant fiber textile, a laminate with the plant fiber textile and a fabricating method of the laminate. The plant fiber textile has a matrix resin and continuous plant fibers distributed within the matrix resin. The plant fibers are subjected to a surface modification pretreatment including a coupling treatment with a coupling agent and/or a fire retardation treatment with a fire retardant. The laminate has a stack structure including a layer of the plant fiber textile and at least one layer selected from a group consisting of following layers: glass fiber, aramid fiber or carbon fiber non-woven cloth or textile, preferably distributed within the matrix resin; polymer fiber non-woven cloth or textile, preferably distributed within the matrix resin; or polymer foam or rubber material.

A fire-resistant material according to an example of the present disclosure includes a base material and at least one of a siloxane polymer and a phosphonate polymer. A method of making a fire-resistant material is also disclosed.

An improved fire-blocking gasket profile for a fire-rated joint, such as a head-of-wall assembly. Fire-rated joints are aimed at inhibiting or preventing fire, heat, or smoke from leaving one portion of a building and entering another portion of a building. Fire-rated joints can also accommodate movement between adjacent building structures, such as between a ceiling and the top of a wall. The improved fire-blocking gasket profile includes a first layer formed of an intumescent material, a second layer formed of a foil lining and a third layer formed of the vinyl profile. The vinyl profile includes an air gap with the intumescent material positioned therein. A vertical portion of the vinyl profile is positioned between a header track and a wallboard in the fire-rated joint. A horizontal portion of the vinyl profile is positioned at least partially within a deflection gap and sealingly engages with the ceiling.

A pultruded material includes a thermosetting resin, and a reinforced fibers impregnated with the thermosetting resin. The thermosetting resin includes a solid resin that contains a fire-resistant resin having a median oxygen index of equal to or higher than, a long-chain fatty acid ester that has a median number of carbons per molecule within a range equal to or more than 3 and equal to or less than 1000, and that has a median flash point within a range equal to or higher than 150 degrees Celsius, and an additive that has a median BET specific surface area within a range equal to or more than 150 m.sup.2/g and equal to or less than 250 m.sup.2/g, and that has a median primary particle diameter within a range equal to or more than 5 nanometers and equal to or smaller than 20 nanometers.

The invention relates to a multilayer thermal insulation panel for construction (100) and manufacturing method thereof. Such panel comprises: a main layer (1) in thermally insulating material which comprises a first surface (10) and a second surface (20); a first backing layer (2) of the main layer connected to the main layer along the first surface (10); a second backing layer (5) of the main layer connected to the main layer along the second surface (20). At least one of such first (2) and second (5) backing layers comprises: a reinforcement layer (3) in fibrous material, a fire-resistant (4) and thermally insulating layer, a cladding layer (6) of the reinforcement layer (3); a binding layer (7) positioned on a surface (8) of the fire-resistant layer (4) in such a way that the fire-resistant layer is sandwiched between the cladding layer (6) and the binding layer. The panel is characterised in that the binding layer (7) is manufactured by means of. a spray-applied aqueous solution of sodium silicates on the surface (8) of the fire-resistant layer (4).

A yarn comprising a plurality of bicomponent filaments having a first region comprising a first polymer composition and a second region comprising a second polymer composition, each of the first and second regions being distinct in the bicomponent filaments; each bicomponent filament comprising 5 to 60 weight percent of the first polymer composition and 95 to 40 weight percent of the second polymer composition; wherein the first polymer composition comprises aramid polymer containing 0.5 to 20 weight percent discrete homogeneously dispersed carbon particles and the second polymer composition comprises modacrylic polymer being free of discrete carbon particles; the yarn having a total content of 0.1 to 5 weight percent discrete carbon particles.

This invention relates to a biodegradable polymer composition which is particularly suitable for use in the manufacture of articles having a high heat deflection temperature (HDT) by injection moulding and thermoforming.
