| 20090114343 | Hot melt adhesive for PTFE - Hot melt adhesives include a thermoplastic terpolymer of vinylidene fluoride, tetrafluoro ethylene and hexafluoropropylene and a terpolymer of glycidyl methacrylate, ethylene and an acrylic ester. The adhesives will bond well to a variety of substrates, in particular substrates of very low surface energy such as polytetrafluoroethylene (PTFE). | 05-07-2009 |
| 20100218974 | Multi-layer insulated conductor with crosslinked outer layer - An insulated conductor and method for making it are disclosed. The insulated conductor includes an elongate conductor and a two-layer insulation system. The two-layer insulation system has a first insulating layer including an aromatic thermoplastic material adjacent with the elongate conductor. The first insulating layer has a thickness along its length of less than about 0.051 mm (0.002 inch). The insulation system also includes a second insulating layer including a crosslinked fluoropolymer adjacent the first insulating layer. The volume of the first insulating layer is less than about 26% of the total volume of the insulation system. | 09-02-2010 |
| 20100218975 | Multi-layer insulated conductor with crosslinked outer layer - An insulated conductor and method for making it are provided. The insulated conductor includes an elongate conductor and an insulation system, the insulation system having an extruded inner insulating layer including an aromatic thermoplastic material adjacent the elongate conductor, an extruded intermediate layer adjacent the inner insulating layer, and an extruded outer insulating layer including a crosslinked fluoropolymer adjacent the intermediate layer. The inner insulating layer has a thickness along its length of less than about 0.051 mm (0.002 inch) and has a volume that is less than about 28% of the total volume of the insulation system. | 09-02-2010 |
| 20100219555 | Method for extrusion of multi-layer coated elongate member - A method of making a multi-layer insulated elongate member is disclosed. The method includes providing an elongate member and tube extruding a first thermoplastic material onto an outer surface of the elongate member to create a first layer having a thickness less than or equal to 0.064 mm (0.0025 inch) using a first extruder apparatus. The method further includes using a second extruder apparatus for pressure extruding a compound comprising a second thermoplastic material different from the first thermoplastic material onto an outer surface of the first layer to create a second layer. The second layer fully wets the first layer and the flow point of the first thermoplastic material is at least 30° C. greater than the extrusion melt temperature of the second thermoplastic material. | 09-02-2010 |
