    摘要: A modified nanocomposite material is provided, which includes an inorganic filler, a silicon dioxide, and a polymer matrix, in which the silicon dioxide is binding with a hydroxyl bond of the inorganic filler to form a silicon dioxide-inorganic filler, and the polymer matrix is dispersed over the silicon dioxide-inorganic filler. Another modified nanocomposite material is further provided, which includes an inorganic filler, a silicon dioxide, and a polymer matrix, in which the silicon dioxide is binding with a hydroxyl bond of the inorganic filler to form a silicon dioxide-inorganic filler, the organic modifier is associated with the silicon dioxide-inorganic filler and the polymer matrix is dispersed over the silicon dioxide-inorganic filler and the organic modifier.

    摘要: A fluoroelastomer mixture is provided with a fluoroelastomer that contains at least approximately 50 parts by weight of the fluoroelastomer mixture and further contains one or more mineral fillers in an amount of approximately 2 parts by weight to approximately 80 parts by weight per 100 parts by weight of the fluoroelastomer. The amine-resistant fluoroelastomer is a copolymer of 1,1-difluoroethylene and 2,3,3,3-tetrafluoropropene or a terpolymer of ethylene, tetrafluoroethylene, and perfluoro(methyl vinyl ether). The mineral fillers improve abrasion and/or wear properties of the fluoroelastomer mixture. A seal is provided with the fluoroelastomer mixture. A shaft seal ring is provided that has a seal body provided with the fluoroelastomer mixture.

    摘要: Disclosed herein is a polyamide composition (PC) including at least one polyamide (A) and at least one carbon black (B), where the surface layer of the at least one carbon black (B) includes not more than 2% by weight of oxygen, based on the total weight of the surface layer of the at least one carbon black (B), and where the weight of oxygen in the surface layer is measured by X-ray photoelectron spectroscopy at an X-ray penetration depth of 2 to 10 nm. Further disclosed herein are a process for producing the polyamide composition (PC), a process for producing a moulded article by forming the polyamide composition (PC), a moulded article including the polyamide composition (PC), and a method of using the at least one carbon black (B) in a polyamide composition (PC) for increasing the shrinkage of moulded articles made from the polyamide composition (PC).

    摘要: A security device (100, 600, 700, 1000, 1050) includes arrangements of image icons (110a, 110b, 615, 715, 1020), arrangements of refractive image icon focusing elements (120, 605, 705, 1010) and a sealing layer (125, 600, 1005), wherein the arrangements of refractive image icon focusing elements is disposed above the arrangements of image icons such that a portion of the arrangements of refractive image icon focusing elements projects a synthetic image, such that the arrangements of refractive image icon focusing elements contact the sealing layer along a non-planar boundary. Further, at least one of the arrangements of refractive image icon focusing elements and the sealing layer comprises an organic resin mixture having a first refractive index, and at least one of the arrangements of refractive image icon focusing elements and the sealing layer comprises a low-refractive index material, the low-refractive index material having a second refractive index.
