摘要： An injection molding machine having a first mold portion and a second mold portion. The second mold portion being movable relative to the first mold portion and together defining a mold cavity. The injection molding machine includes a fluid path extending through the first mold portion. The fluid path has an inlet and a radially continuous, downwardly-extending, circumferential outlet in fluid communication with the mold cavity. The injection molding machine further having a valve ring movably coupled in the first mold portion. The valve ring includes a downwardly extending rim portion substantially disposed within the fluid path. The valve ring is positionable in a closed position where the rim portion engages the circumferential outlet to obstruct flow of the molding material from the fluid path to the mold cavity and an opened position where the rim portion is spaced apart from the circumferential outlet to permit flow of the molding material from the fluid path to the mold cavity. The injection molding machine further includes a heating assembly in thermal communication with at least a portion of the fluid path to maintain the molding material in an uncured state for thermoset rubbers and plastics, and in a molten state for thermoplastics.

摘要： Etching the surface (activating the surface) of a halogenated polymer component with an electron beam generates a set of free radical sites in polymeric chains of the surface that sustain for at least 4 hours in an inert environment. The inert environment is provided by a noble gas, nitrogen, a static free space, and/or a vacuum. Items such as dynamic seals, static seals, gaskets, pump diaphragms, hoses, and o-rings all benefit from precursors made according to the technique.

摘要： Processable rubber compositions contain a vulcanized fluorocarbon elastomer 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 high temperature processing aid 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： Fluoropolymers are made by admixing tetrafluoroethylene, hexfluoropropylene, and vinylidene fluoride; reacting the reaction admixture to generate a set of fluoropolymeric oligomers; irradiating the fluoropolymeric oligomeric precursor admixture (preferably with electron beam radiation) to form free radical sites on individual fluoropolymeric oligomers of the set and generate thereby a set of free radical oligomer derivatives in the fluoropolymeric oligomeric precursor admixture; and reacting the fluoropolymeric oligomeric precursor admixture to derive the fluoropolymer compound from the free radical oligomer derivatives. In a second approach, fluoropolymers are made by admixing tetrafluoroethylene, hexfluoropropylene, and vinylidene fluoride and irradiating the admixture.

摘要： A homogenous fluoropolymeric melt-bonded layer in a multilayer composite coheres to a pervious fluoropolymer layer of fluoroelastomeric thermoplastic and/or etched polytetrafluoroethylene. Before curing, the homogenous fluoropolymer has a stoichiometrically identical monomer unit with the pervious fluoropolymer, the homogenous fluoropolymer liquefaction range supra-point temperature is not greater than that of the pervious fluoropolymer, the homogenous fluoropolymer liquefaction range supra-point temperature is not less than the pervious fluoropolymer liquefaction range sub-point temperature, and the homogenous fluoropolymer liquefaction range supra-point viscosity is less than that of the pervious fluoropolymer. In some multilayer composites, the homogenous fluoropolymeric melt-bonded layer coheres to a third layer of plastic, metal, ceramic, rubber, wood, and/or leather. In such 3+ layer composites, the homogenous fluoropolymeric contains an epoxy compound, a phenoxy compound, silane, and/or a heat-polymerizable thermoplastic oligomer. Various composites according to the technology are adapted for use as gaskets, dynamic seals, compression seals, or o-rings.
