摘要:
Disclosed is a polymer film, preferably a polyamide polymer film, which comprises at least one first layer and a second layer and is laminated onto a fabric. The material of the first layer has a glass transition temperature of less than −10° C. while the material of the second layer has a glass transition temperature of less than 20° C. Preferably, the polymeric materials contain portions of polyamide blocks. The inventive fabric-polymer film laminate is suitable as a laminated material especially for an airbag.

The present invention relates to a composite article and to a process for manufacturing the composite article. The composite article comprises multiple layers including high tenacity fibers incorporated into a fabric and a core thermoplastic resin. The fabric may be coated with a surface treatment agent, a polymer matrix resin. Single or multiple layers of the composite articles may be formed into a composite part having high strength, rigidity, fast molding cycle time and extremely good conformability in a 3-dimensional mold. The composite parts formed by this process have high part strength in all directions.
摘要:
A roof membrane and a roof system employing a EPDM membrance which is compatible with a bituminous adhesive. The membrance includes an outer layer of polymeric layer such as EPDM bonded to a polyester protective layer which is in turn bonded to a fleecy material. This can be adhered to a roof deck surface using hot asphalt or bitumen which bonds the fleecy material to the roof deck in turn holding the EPDM in place. The polyester layer prevents the asphaltic material from attacking and dissolving the EPDM with the fleecy material providing good adhesion between the polyester and the EPDM.
摘要:
A polymeric sheet having excellent cut-resistance contains: (A) a polymeric material, and (B) a hard filler distributed in the polymeric material, the hard filler having a Mohs hardness value of at least about 3.0, the hard filler being in the form of particles having an average diameter sufficient to provide cut-resistance properties to the polymeric material but which is no more than about 5 microns. The cut-resistant sheet may be in the form of a conventional sheet, a film, a coating, a composite and the like, and may be used to form cut-resistance articles such as, e.g., protective garments and tires. The cut-resistant sheet may also be laminated onto a textile fabric to form a composite from which articles, e.g., garments, can be formed.
摘要:
An inherently light- and heat-stabilized polyamide has at least one piperidine compound bonded to the backbone polymer chain and at least one 4-amino-2,2,6,6-tetramethylpiperidine compound bonded to the backbone polymer chain. The inherently light- and heat-stabilized polyamide may be used to form articles such as, for example, fibers, carpets, yarns, and textile fabrics.

This invention is a water-resistant film for lamination to a textile material, and the flexible, laminated product produced therewith. The film has a permeability of at least 0.0008 metric perm-cm. at 20.degree. C. and 65 percent relative humidity and of at least 0.0006 metric perm-cm. at 30.degree. C. and 50 percent relative humidity. The film is formed from a block copolymer having a number average molecular weight of from about 15,000 to about 35,000. The block copolymer contains polymer segments prepared by the amination of a polyether formed by treating a polyethylene glycol with an alkylene oxide of three or more carbon atoms. The product is a laminant of a layer of the described film and a layer of a textile material, and is useful in the formation of water-resistant, moisture permeable articles such as garments, tarpaulins, tents, and the like.

摘要:
Waterproof, water vapour-permeable multilayer membrane having at least one first and one second layer, with all the layers being made of a thermoplastic polymer from the group of polyether esters, the group of polyether amides or the group of polyether urethanes and being joined together, characterised in that contiguously arranged layers are made of thermoplastic polymers from different groups.
摘要:
The present invention relates to a process of obtaining an industrial fabric with porous and controlled plasticized surface and an industrial fabric with the mentioned characteristics thereof. The invention also relates to an industrial fabric such as press fabric for use in the press section of a paper machine with enhanced aesthetic properties by the use of plasticizers and optional heat and/or pressure treatment.
