Aspects of the invention are found in a heating component having a composite material coated on a support. The composite material includes a fluorinated or silicone polymer and inductively-heatable particles. Additional aspects of the invention are found in a heating belt having a flexible support coated with a composite material. The composite material includes a polymer material and inductively-heatable particles. Further aspects of the invention are found in a system for heating an article. The system includes a heating belt and a field generator. The heating belt includes a flexible support coated in a composite material. The composite material includes a polymeric matrix and inductively-heatable particles. The field generator induces a field about the heating belt. The inductively-heatable particles heat in the presence of the field.

Inductively heatable components

A multilayer composite has a generally adhesion resistant, protective layer and an adjacent second polymeric film. The composition of the protective layer includes a fluoropolymer and the second polymeric film is a polymer free of fluoropolymer. The size of the protective layer facing the second polymeric layer is rendered bondable to the non-fluoropolymer of the second polymeric layer prior to assembling the layers in the composite. The composite is well adapted to being produced in a vertical coating tower. The tower utilizes a carrier web onto which the fluoropolymer layer and second polymeric layer are deposited from respective casting films. Mirror image composites can be formed simultaneously on opposite sides of the carrier web.

Multilayer composite and method of making same

Melt-fabricable thermoplastic fluoropolymer having pendant functional groups is thermally cross-linked in the presence of polyfunctional nucleophile.

The disclosure is directed to a method for cleaning an oven. The method includes placing an oven liner in an oven. The oven liner has a first major surface formed of silicone elastomer and has a second major surface formed of fluorinated polymer. The method further includes cooking food items in the oven and over the oven liner and removing the oven liner.

The present invention provides improved medical introducer devices which incorporate a single or multi-layer PTFE peelable sheath. Devices of the present invention are suitable for use in inserting an ancilliary medical device, e.g., a catheter, guide wire and the like, into a patient. Methods of the present invention also are disclosed which employ a precision sintering process in order to produce sheaths having excellent tear properties and optimal peelability.

Peelable PTFE sheaths and methods for manufacture of same

Articles such as tubing and wire insulation made from fluoropolymer having functional groups exhibit improved mechanical properties.

Articles of functional fluoropolymer

Coextruded layers of polyamide and fluoropolymer adhere to one another without an intervening tie layer by adhesive activation of polyamide of the polyamide layer, e.g. by incorporating into the polyamide layer a dispersed phase of maleic anhydride-grafted ethylene/propylene/diene copolymer. The fluoropolymer is a copolymer of ethylene with perhalogenated comonomer or a copolymer of tetrafluoroethylene with perfluorinated comonomer.

Coextruded fluoropolymer/polyamide laminate

Structures for transport and containment of hydrocarbon fluids for motorized transportation vehicles are made from a blend of polar-grafted fluoropolymer dispersed in a matrix of polar polymer. The blend can be in a component element of a composite structure.

Hydrocarbon fluid containment for motorized transportation vehicles

Methods are disclosed for producing multi-layer peelable sheaths having formed tips, for use as medical introducer devices, e.g., sheaths for inserting a catheter or the like into a patient. The methods include the steps of preparing a first composition blend for forming an inner layer of the multi-layer sheath, preparing a second composition blend for forming an outermost layer of the multi-layer sheath, combining the first and the second composition blends into a multi-layer pre-form, processing the multi-layer pre-form for producing tubing, and forming a tip at one end of the tubing using a thermal process, thereby producing the multi-layer sheath having the inner layer, the outermost layer, and the formed tip. The methods of the present invention include adding a detectable material to the blend used for making the inner layer for facilitating external visualization of the multi-layer sheath, thereby achieving a sheath with a formed tip having no visible discoloration. The methods also incorporate a reduced sintering process for achieving an optimally cured, peelable sheath having excellent tear properties.

Method for tip forming peelable PTFE tubing

A melt-mixed blend of polyamide and grafted fluoropolymer having polar functionality exhibits surprisingly low permeability and can bond to fluoropolymer or polyamide without an intervening adhesive layer. The blend is useful as a component of laminates, such as fuel hose.
