A composite includes a first layer of a first fluoropolymer; a second layer of at least one ply of a reinforcing fabric overlying the first layer; and a third layer of a second fluoropolymer overlying the second layer opposite to the first layer, wherein the first layer, the third layer, or combination thereof have an outer surface that is defect free; wherein the composite has a continuous length of at least about 3 meters. Embodiments of such composites can find applications, for example, as processing aids for an electronic device, a food, a polymer, insulating an electrical device, or heat sealing a polymer.

Methods of making bearings using pressure sensitive macromolecular adhesive polymers and pressure sensitive polymer compositions capable of integrating fluoropolymeric properties with a catechol-amine functionality to form an adhesive system that allows bonding between metallic substrates and fluoropolymers are disclosed. Also disclosed are core-shell polymeric particles comprised of a core and a shell comprising a thermoplastic polydopamine polymer that may be prepared as a colloidal suspension and used as a hot-melt pressure sensitive adhesive capable of binding low surface energy materials, such as polyolefins and fluoropolymers, to diverse materials including metals in making bearings and/or bearing components.

The present invention provides a process for preparing a functionalised polymeric chromatography medium, which process comprises (I) providing two or more non-woven sheets stacked one on top of the other, each said sheet comprising one or more polymer nanofibres, (II) simultaneously heating and pressing the stack of sheets to fuse points of contact between the nanofibres of adjacent sheets, and (III) contacting the pressed and heated product with a reagent which functionalises the product of step (II) as a chromatography medium.

There is provided a laminate membrane for an implant, comprising: an inner layer having an inner layer thickness; a first covering layer disposed on one side of the inner layer, the first covering layer having a first covering layer thickness; and a second covering layer disposed on another side of the inner layer, the second covering layer having a second covering layer thickness.

The present invention relates to a coating composition comprising a fluoropolymer and a dopamine derivative. Further, the present invention relates to a process for coating a substrate, comprising the steps of (a) providing a coating composition comprising a fluoropolymer, a dopamine derivative and a solvent; (b) locating the coating composition on a substrate; (c) heating the coated substrate to remove the solvent; and (d) optionally pressing the heated coated substrate against another material surface to bond these to each other. The present coating composition allows the bonding of fluoropolymers through a process that eliminates the need for mechanical keying and hazardous or costly etching processes.

A method for manufacturing a laminate sheet including a fluororesin film and a silicone rubber sheet that are adhered to one another, where the fluororesin film has a reactive functional group as a result of a surface treatment, the side with the reactive functional group is overlapped with an organic peroxide-containing millable-type silicone rubber composition, where the silicone rubber composition is sheet-shaped and the organic peroxide has a one-minute half-life temperature in the range of 100−150° C., and the silicone rubber composition is cured by being heated under pressure at 90-135° C. The laminate sheet has a peel adhesion strength of 3N or more. The four corners of a 120 mm square test sample of the laminate sheet do not curve into one end of a semicircular arc shape or one end of a C shape, and the average warpage value of the four corners is 35 mm or less.

A film having a dielectric dissipation factor at a frequency of 1 kHz and 160° C. of 0.02% or lower and a dielectric breakdown strength at 160° C. of 400 V/μm or higher. Also disclosed is a film including at least one fluoropolymer selected from a tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer and a tetrafluoroethylene/hexafluoropropylene copolymer, the fluoropolymer having a crystallinity of 65% or higher.

An interior material of a vehicle includes: a fabric layer made of a tricoat fabric, a foam layer disposed on a lower surface of the fabric layer, and an antifouling layer disposed at least between an upper surface of the fabric layer or the fabric layer and the foam layer. The tricoat fabric includes a combination of at least one of a polyurethane yarn, a high-elongation polyester yarn, or a polyester yarn.

Coated articles are provided comprising: (a) a substrate that demonstrates electrical conductivity, wherein the substrate is an electronic component of a circuit assembly; (b) a moisture barrier coating layer; and (c) an encapsulating plastic coating layer. The moisture barrier coating layer may be applied to the surface of the substrate with the encapsulating plastic coating layer applied on top of the moisture barrier coating layer, or vice versa.

Articles and insulating systems include a wicking layer, an incompressible insulation layer, and a water scavenging system comprising a superhydrophobic layer in operative communication with one or more water collecting components.
