The present invention relates to an agglomerated zeolite adsorbent containing at least one polymer matrix that is greatly laden with at least one zeolite adsorbent. The invention also relates to the method for preparing such an adsorbent and to the uses thereof, particularly as an adsorbent of moisture, odors, volatile organic components, and the like.

Zeolite adsorbent having an organic binder

The invention relates to an improvement to conveyors comprising moving elements which slide over fixed elements such that at least one moving element made of a polyamide-based blend (A) slides over a fixed element made of polyacetal and/or such that at least one moving element made of polyacetal slides over a fixed element made of a polyamide-based blend (A).

Polyamide conveyor elements

The invention relates to compositions containing a polyamide matrix (A) and a polyolefin dispersed phase (B), in which compositions the polyamide has a melting point below that of PA-6 and the dispersed phase consists of at least one polyolefin (B) chosen from functionalized polyolefins (B1) and non-functionalized polyolefins (B2). Advantageously, (A) is PA-6/12 or PA-6/6,6. These compositions are useful for making monolayer or multilayer films by extrusion with EVA or PE.

Compositions based on polyolefins and low-melting-point polyamides

The present invention relates to a process for forming composite shaped articles used for athletic shoe soles, tubes, pipes, transmission belts and conveyor belts, comprising a vulcanized elastomer directly or autogenously bonded, that is, essentially in the absence of adhesive, to a thermoplastic elastomer comprising recurring polyamide-6 and polyether structural units, such as thermoplastic polyetheresteramide elastomers, are provided. The article is prepared by a process comprising placing a thermoplastic elastomer component into a vulcanization mold, overmolding onto at least a portion of the surface area of one face surface of the thermoplastic elastomer component with a vulcanizable elastomer component, and vulcanizing the vulcanizable elastomer component at a temperature below the melting point of the thermoplastic elastomer component but over a wide temperature range, which can be about 40&deg; C. or higher.

Composite shaped articles comprising vulcanized elastomers autogenously bonded to polyamide/polyether thermoplastic elastomers

Composite including a rubber/thermoplastic blend adherent by itself to a thermoplastic material; the blend is in the form of a thermoplastic matrix containing rubber nodules functionalized and vulcanized during the mixing with the thermoplastic. Composite articles obtained by overmolding the vulcanized rubber/thermoplastic blend onto the thermoplastic.

Blends of thermoplastic and rubber which are adherent to thermoplastics

Vulcanized rubbers modified by thermoplastics

The invention relates to films made of compositions comprising:

Films based on polyamides and on polyolefins

Antistatic film for packaging materials diffusing volatile products

The invention relates to belts made of thermoplastic polymer (A) and comprising a sufficient amount of a polymer (B) to render them antistatic, the said polymer (B) comprising polyethylene glycol blocks. Use is advantageously made of polymers (A) containing polyamide-6 (PA-6) or polyamide-12 (PA-12) blocks and polytetramethylene glycol blocks and polymers (B) containing PA-6 or PA-12 blocks and polyethylene glycol blocks.

Antistatic belts

Composite including a rubber/thermoplastic blend adherent by itself to a thermoplastic material; the blend is in the form of a thermoplastic matrix containing rubber nodules functionalized and vulcanized during the mixing with the thermoplastic. Composite articles obtained by overmoulding the vulcanized rubber/thermoplastic blend onto the thermoplastic.

A material is provided comprising: (a) a polyamide; (b) a polymer having PA blocks and polyether PEG blocks; (c) optionally a polyolefin; (d) a functionalized polyolefin; the various constituents being present in amounts by weight, a, b, c and d such that: a&gt;0; b&gt;0; c+d&gt;0; a+b+c+d=100; with a/b&gt;0.2; (a+b)/(c+d)&gt;1; and b/(a+b+c+d)&lt;0.5. A film which is non-porous but breathable, i.e. porous to water vapor but not to water, and an antistatic object obtained from this material are also provided.

Material comprising a polyamide, a polymer having polyamide and

Films based on polyamide and on polymers containing polyamide blocks and

The subject of the invention is a conveyor belt comprising an outer polyamide layer and an inner layer of a thermoplastic block polymer, intended to be used in particular in the food or agri-foodstuff industry.
