Articles containing functional polymeric phase change materials and methods of manufacturing the same
A method of producing a temperature regulating article is disclosed. The method includes combining a functional polymeric phase change material with a substrate. The functional polymeric PCM has the capability of absorbing or releasing heat to adjust heat transfer at or within a temperature stabilizing range and having at least one phase change temperature in the range between 10 C. and 100 C. and a phase change enthalpy of at least 5 Joules per gram, the functional polymeric PCM has a backbone chain, side chains, and a crystallizable section. The side chains form the crystallizable section. The functional PCM carries at least one reactive function on at least one of the side chains or the backbone chain. The reactive function is capable of forming at least a first covalent bond with the second material or with a connecting compound capable of reacting with reactive functions of the second material.
Aircraft Windows
The present invention provides an aircraft window including a polyurethane including a reaction product of components including (a) about 1 equivalent of at least one polyisocyanate; and (b) about 1 equivalent of 1,4-cyclohexane dimethanol based upon the about 1 equivalent of the at least one polyisocyanate, and other aircraft window compositions.
Fabric with contaminant resistant nanoparticle coating and method of in situ application
A fabric is treated by applying a nanoparticle type coating to improve their resistance to contamination by foreign matter. The coating is applied during fabric manufacture and cured during heat setting. Alternatively, the coating applied or renewed by utilizing an existing shower or locating a spray boom or other suitable coating application device to apply the coating to the fabric in a controlled, uniform manner. Prior to application of the coating, the fabric is first thoroughly cleaned such as by showering or spraying, and then dried. Following controlled application of the coating, any excess material is removed by a suitable means, such as by vacuum, and the remaining coating on the fabric is then cured, either by utilizing the ambient heat of the equipment or by a portable bank of heaters. In this manner, the fabric does not have to be removed from the machine in order to apply or renew the contaminant resistant coating.
Surfactant treatment for a sterilization wrap with reduced occurrence of wet packs after steam sterilization
A surfactant treatment is provided that can result in a sterilization wrap that can have a bacterial filtration efficiency of at least 94 percent as determined according to ASTM F2101. The surfactant treatment includes a surfactant consisting essentially of carbon, hydrogen, and oxygen atoms. Wrapping packs in a wrap treated with said surfactant treatment in an amount ranging from greater than 0 to 2 weight percent based on the dry weight of the wrap results in the production of fewer wet packs after steam sterilization compared to when packs are wrapped with an identical wrap without said surfactant treatment. A sterilization wrap comprising a nonwoven fabric and a dried residue surfactant treatment that is essentially free of silicon, potassium, phosphorus, and sulfur is also provided, where wrapping packs to be sterilized in the surfactant treated wrap reduces the occurrence of wet packs after steam sterilization compared using an untreated wrap.
Pigment compositions comprising anthocyanic vacuolar inclusions
The invention provides a pigment composition comprising anthocyanic vacuolar inclusions or AVIs from a plant, and an acceptable carrier. The invention also provides methods for colouring products with the pigment composition, and products comprising the pigment composition or AVIs.
RIGID BALLISTIC COMPOSITES HAVING LARGE DENIER PER FILAMENT YARNS
A rigid ballistic-resistant composite includes large denier per filament (dpf) yarns. The yarns are held in place by a resin to form a rigid composite panel with improved ballistic performance. The large dpf yarns may be selected from aromatic heterocyclic co-polyamide fibers, polyester-polyarylate fibers, high modulus polypropylene (HMPP) fibers, ultra high molecular weight polyethylene (UHMWPE) fibers, poly(p-phenylene-2,6-benzobisoxazole) (PBO) fibers, poly-diimidazo pyridinylene (dihydroxy) phenylene (PIPD) fibers, carbon fibers, and polyolefin fibers.
Polyurethanes, articles and coatings prepared therefrom and methods of making the same
The present invention provides polyurethanes including a reaction product of components including: (a) an isocyanate functional urethane prepolymer comprising a reaction product of components including: (i) about 1 equivalent of at least one polyisocyanate; and (ii) about 0.1 to about 0.5 equivalents of at least one diol having 2 to 18 carbon atoms; and (b) about 0.05 to about 0.9 equivalents of at least one branched polyol having 4 to 18 carbon atoms and at least 3 hydroxyl groups; and (c) up to about 0.9 equivalents of at least one polyol different from branched polyol (b) and having 2 to 18 carbon atoms, wherein the reaction product components are essentially free of polyester polyol and polyether polyol; compositions, coatings and articles made therefrom and methods of making the same.
ADHESION COMPOSITION AND TEXTILE MATERIALS AND ARTICLES TREATED THEREWITH
This invention relates to improved adhesion compositions and textile materials and articles treated therewith. The improved adhesion composition comprises a non-crosslinked resorcinol-formaldehyde and/or resorcinol-furfural condensate (or a phenol-formaldehyde condensate that is soluble in water), a rubber latex, and an aldehyde component such as 2-furfuraldehyde. The composition may be applied to textile substrates and used for improving the adhesion between the treated textile substrates and rubber materials. End-use articles that contain the treated textile-rubber composite include, without limitation, automobile tires, belts, and hoses as well as printing blankets.
