摘要:
Novel solid benzoate ester compositions are mixtures comprising the trans- and cis- structural isomers of 1,4-cyclohexanedimethanol dibenzoate wherein the trans isomer constitutes from 1 to 66 or from 72 to 99 weight percent of the mixture. The properties imparted to a variety of polymer compositions, including hot melt adhesives, cannot be achieved using the commercially available mixture of these isomers.
摘要:
A solvent-free multilayer laminated material comprises a lower substrate layer comprising a thermoplastic polymer or a mixture of thermoplastic polymers, an intermediate layer arranged thereon and comprising a flexible material, a further fibrous intermediate layer comprising plastic, which is provided with an adhesive material and an upper layer comprising metal, comprising plastic or comprising wood or wood-like materials. It does surprisingly not show any deformation even under exposure to temperatures of about 80 o C over a period of up to 40 days and can be used for the production of articles of furniture, floor coverings, wall panels or shaped articles for the electrical, construction or automotive industry.
摘要:
The presently described technology provides a machine-direction stretch elastic laminate having in addition cross-direction stretch. The elastomeric laminate comprises an elastic film layer laminated to at least one nonwoven fabric layer and may be used in elasticized features of various articles, such as disposable absorbent articles. Methods for producing the elastic laminate are also described.
摘要:
A puncture and abrasion resistant, air and water impervious laminated fabric is provided. The laminated fabric includes a woven fabric base layer having warp and weft yarns, with at least 50 percent of the fibers in the warp yarns being formed of high performance material. A first thermoplastic film is bonded by heat and pressure to at least one of the sides of the fabric base layer. The first thermoplastic film is formed of ethylene vinyl acetate. A second thermoplastic film is bonded by heat and pressure to the first thermoplastic film on at least one of sides of the fabric. The second thermoplastic film is formed from either high density polyethylene or low density polyethylene.
摘要:
Polyolefin dispersions, froths, and foams and articles manufactured therefrom are disclosed. Also disclosed is a method for generating a thermoplastic foam from an aqueous dispersion. The aqueous dispersion may include a thermoplastic resin, water, and a stabilizing agent. The method may include adding at least one frothing surfactant to the aqueous dispersion to form a mixture, adding a flame retardant and/or a phase change material, frothing the mixture to create a froth, and removing at least a portion of the water to produce the foam.
摘要:
A method of forming an exterior surface protective structure (12) for an aircraft (10) includes uniting a loaded surfacer (52) having a carrier (51) to a hybrid prepreg substrate (32). The prepreg substrate (32) includes a carbon fabric (44) with an integral conductive component (48) having conductivity with in a metal conductivity range and is united to a base substrate (30). The loaded surfacer (52) and the prepreg substrate (32) are cured, which includes interfacially adhering matter between the loaded surfacer (52) and the prepreg substrate (32). A protective fabric system (12) for an exterior (14) of an aircraft (10) includes the base substrate (,30). The hybrid prepreg substrate (32) is coupled to the base substrate (30). The loaded surfacer (52) with the carrier (51) is interfacially adhered to the prepreg substrate (32).
