摘要： Improved dental flosses include two or more components selected to provide desired properties to the floss. The improved flosses may comprise one or a plurality of multicomponent filaments, each filament including an inner core selected to provide strength to the floss, and an outer layer selected to provide a desired surface property. The improved flosses also may comprise one or a plurality of core filaments embedded in a single body sheath. The filament component provides desirable physical properties to the floss, such as tensile strength, while a floss body sheath component provides desirable surface properties.

摘要： A processable rubber composition contains a double cured fluorocarbon elastomer dispersed in a matrix of a thermoplastic polymeric material. The cured elastomer contains repeating units derived from one or more fluorine-containing monomers, and further contains low levels of a peroxide cure site that contains at least one of a C—Cl bond, a C—Br bond, a C—I bond, and an olefin. In one embodiment the matrix forms a continuous phase and the vulcanized elastomeric material is in the form of particles forming a non-continuous phase. In various embodiments, the processable compositions are thermally processed into molded articles that exhibit a high degree of base resistance, especially a high degree of resistance to degradation of physical properties upon exposure to fluids containing strong nucleophiles such as amines.

摘要： A curable fluorocarbon elastomer is dynamically cured in the presence of a major amount of a non-curing thermoplastic material and a minor amount of a second fluorocarbon elastomer that does not cure under the dynamic vulcanization conditions. The non-curing elastomer is preferably present at from 1 to 20 parts based on 100 parts of the curing fluorocarbon elastomer. Processable rubber compositions comprise a continuous phase of a thermoplastic material, particles of a cured fluorocarbon elastomer dispersed in the continuous phase, and an uncured fluorocarbon elastomer at a level of 10 parts or less per 100 parts of the cured fluorocarbon elastomer. Shaped articles such as gaskets and seals are produced by thermoplastic processing of the processable rubber compositions.

摘要： Processable rubber compositions contain a vulcanized fluorocarbon elastomer and wear reducing additives dispersed in a matrix of a thermoplastic polymeric material. In one embodiment the matrix forms a continuous phase and the vulcanized elastomeric material is in the form of particles forming a non-continuous phase. The compositions are made by combining a curative, an uncured fluorocarbon elastomer, a wear reducing additive and a thermoplastic material, and heating the mixture at a temperature and for a time sufficient to effect vulcanization of the elastomeric material, while mechanical energy is applied to mix the mixture during the heating step. Shaped articles such as seals, gaskets, O-rings, and hoses may be readily formed from the rubber compositions according to conventional thermoplastic processes such as blow molding, injection molding, and extrusion.

摘要： A composite having two structural layers of (independently) metal, polymer, or ceramic is connected with a polymeric adhesive layer positioned in solid form between the two layers. The adhesive layer is inter-bonded after positioning with at least one structural layer by a bi-modal molecule derived from treating the solid adhesive and other layers with radiation (preferably, electron beam radiation). Items such as a dynamic and static seals, gaskets, pump diaphragms, hoses, and o-rings all benefit from the technique.
