Abstract:
A flexible hose having a non-fluorinated rubber inner tube, a non-fluorinated rubber outer cover, an intermediate barrier layer consisting essentially of ethylene-vinyl alcohol copolymer (EVOH) having an ethylene content less than 30 mole %, and preferably a textile reinforcement between said barrier layer and said outer cover. A non-fluorinated rubber tie layer may be included between the barrier and the reinforcement. Permeability to ethanol- and methanol-containing fuels is very low.
Abstract:
A reinforced polymer composite includes a polymer matrix and a strengthening agent. The strengthening agent includes highly crystalline cellulose nanocrystals (CNC) and a stabilizing agent. The crystalline cellulose nanocrystals (CNC) have dimensions of about 3 to 5 nm in width and about 100 to 300 nm in length and a density of about 1.6 g/cm3 and the stabilizing agent may be one of Boehmite nanoclay (Boe) and Cetyltrimethylammonium Bromide (CTAB) or a combination of both.

Abstract:
A nonwoven trough and method of construction thereof are provided. The nonwoven trough includes at least one nonwoven wall formed from a mixture of bonded natural cellulosic fibers and thermoplastic fibers. The at least one nonwoven wall extends along a longitudinal axis and has a midsection and opposite end portions. The midsection has a base and a pair of walls extending upwardly from the base to provide the midsection with a generally U-shaped cross-section taken generally transversely to the longitudinal axis. At least one flange extends laterally from the at least one nonwoven wall, wherein the flange is configured for attachment to a vehicle member.
Abstract:
The present invention provides, among other things, compositions comprising nanofibrils, at least one maleic-anhydride (MA) copolymer and at least one matrix polymer, and methods of making such compositions. The provided methods and compositions allow for the production of composites with unexpectedly superior properties including improved impact resistance, tensile modulus of elasticity, tensile strength, and flexural modulus of elasticity as compared to previously known composites. In some embodiments, the present invention provides methods including the steps of providing cellulose nanofibrils, associating the cellulose nanofibrils with a maleic-anhydride (MA) copolymer to form a nanofibril-MA copolymer blend, preparing the nanofibril-MA copolymer blend for addition to a matrix polymer, and forming a composite by associating the nanofibril-MA copolymer blend with the matrix polymer, wherein the amount of cellulose nanofibrils in the composite is between 3% and 50% by weight of the composite.
Abstract:
L'emballage souple de forme essentiellement tubulaire destiné à contenir un produit semi-liquide ou pâteux comprend une jupe, une tête et optionnellement un bouchon, la jupe étant formée par une feuille enroulée et comportant une soudure longitudinale permettant l'assemblage de ses bords ; la tête étant fixée sur le pourtour de l'une des extrémités de la jupe. La jupe comprend un taux d'au moins 30% de matière recyclée ou de matière issue de ressources renouvelables et il comporte un ajout de matière au moins sur le côté intérieur de la jupe de façon à supprimer une discontinuité de la face interne dans la zone de la soudure longitudinale.
Abstract:
The invention relates to a covering panel (1, 25) with a single piece of extruded support plate (2), made from synthetic plastic material, preferably at least in part of recycled synthetic plastic material, with a flat and even top surface (3), a bottom face (18) and with pairs of opposite sides (4,5; 34, 35) that are provided with complementary profile edges in the form of a male profile edge (6; 26; 36) on the one side and a female profile edge (7; 27; 37) on the other, where said male profiled edge (6, 26, 36) can be connected, in a clamping or anchoring manner, to a female edge (7, 27) of an equal adjacent covering panel (8, 28), preferably according to a direction D that runs perpendicular to said top surface. In their bottom face (18) there are a number of strip-shaped recesses (19) that run according to the direction of extrusion and that alternate in that place with a number of support strips (20), of which at least a part (46) has a width S along that bottom face that complies with 1,5T
Abstract:
A pultrusion method for forming a laminated composite with a predetermined profile and the product obtained. An apparatus is used that comprises at least two spools (2) for supplying elongated reinforcements (1). A collator (3) receives the elongated reinforcements (1) and arranges the reinforcements in layered relationship to form a layered elongated bundle (4). A supply member wets the layered elongated bundle with plastisol to form a wetted elongated bundle (8). The wetted elongated bundle (8) is transported through a pultrusion die (9) wherein the wetted layered bundle is molded into the predetermined profile. A curing section (11) cures, or converts, the wetted layered bundle (8) into the layered composite. A particularly preferred embodiment is an extrusion comprising a reinforcing material wherein said reinforcing material comprises a fiber reinforced plastisol.
