摘要:
La présente invention concerne un tuyau utilisable pour un circuit d'admission d'air de moteur de véhicule automobile, et ce circuit d'admission d'air en particulier pour l'admission d'air en sortie d'un turbocompresseur qui incorpore au moins un tel tuyau. Ce tuyau (1) comporte au moins une couche élastomère interne (10), une couche élastomère externe (16), une couche élastomère intermédiaire (12) et une structure de renforcement (14) qui est située entre les couches intermédiaire et externe et qui comprend des fils à base d'un polyester aliphatique, tel qu'un PET, chaque couche intermédiaire et externe étant constituée d'une composition à base d'au moins un copolymère d'un acrylate (ACM). Selon l'invention, ladite composition est réticulée par un système choisi dans le groupe constitué par ceux à base d'au moins un savon associé au soufre, à un dérivé d'urée et ceux à base d'un thiadiazole.

An absorbent article of the present invention may comprise a topsheet, an outer cover, and an absorbent core disposed therebetween. The outer cover may comprise an extrusion bonded laminate. The EBL may comprise a multi-layer coextruded elastomeric film and a nonwoven. The film may comprise a core layer, a first outer layer, and a second outer layer, wherein the core layer is between the first and second outer layers. The nonwoven may comprise fibers and/or filaments. The first outer layer may be non-adhesively joined to the nonwoven via extrusion coating. Further, the outer cover may be elastic to at least about 50% engineering strain. The nonwoven may have high chemical affinity for the first outer layer. The first outer layer may have a low chemical affinity for the core layer; and the multi-layer coextruded elastomeric film may have a basis weight no greater than about 40 gsm.

摘要:
A multi-layer tube ( 1 ) which comprises a base tube ( 3 ) and a coating layer ( 2 ) laminated on the inner surface of the base tube ( 3 ). The base tube ( 3 ) is made of a fluororubber type thermoplastic elastomer composed of rubber phase and a crystalline phase and has a hardness of HDA 40 or more and HDA 70 or less as measured according to JIS K 7215. The coating layer ( 2 ) is made of a blend of the above fluororubber type thermoplastic elastomer with a (vinylidene fluoride)-(hexafluoropropylene)-(tetrafluoroethylene) tenary copolymer and has a hardness of HDA 70 or more and HDD 80 or less as measured according to JIS K 7215.

A vulcanized fluorine rubber is disclosed which is obtained by vulcanizing 100 parts by mass of a mixture, wherein a material fluorine rubber (A) which is blended in advance with an appropriate amount of a vulcanizing agent and a material fluorine rubber (B) which is not blended with any vulcanizing agent are mixed at a ratio from 8/2 to 3/7, and a composition composed of 1-10 parts by mass of an acid acceptor and 0-5 parts by mass of other compounding ingredients which are blended if necessary. The number-average molecular weight of the material fluorine rubber (A) and material fluorine rubber (B) is from 3.5 × 104 to 2.0 × 105.
摘要:
A carpet pad comprises a two-layer structure of a cushion and a barrier film formed of a synthetic polymeric material free of any fibrous substrate laminated thereto. The barrier film may be directly bonded to the cushion or bonded thereto using a layer of adhesive. The carpet pad is simultaneously impermeable to liquid deposited onto the pad from above the barrier film and permeable to moisture vapor at a moisture vapor transmission rate of at least 14.6 grams per square meter per twenty-four hours (14.6 g/m2/24 hours). The carpet pad is sufficiently durable to maintain liquid impermeability as measured by a Vetterman Drum Wear Test/Staining/Stain Cleaning Test after at least ten thousand cycles or under a pressure of at least eight pounds per square inch (0.56 kg per square meter) as measured by a Modified Mullen Bursting Strength Test.
