摘要:
The disclosure is directed to a barrier structure including a fluoropolymer layer, a polymeric layer, and an adhesive layer. The barrier structure has a chemical permeation breakthrough detection time greater than about one hour for hazardous chemicals as measured by ASTM F739. The disclosure is further directed to a method of forming the aforementioned barrier structure. The barrier material is designed to be suitable for construction of shelters, clothing, containers and other articles requiring barrier properties.

摘要:
A coated fabric includes a reinforcement, a first coating disposed on the reinforcement, and a second coating disposed on the first coating. The first coating includes perfluoropolymer. The second coating includes perfluoropolymer and a silicone polymer in an amount in a range of 2 wt % to 30 wt %.
摘要:
A grilling belt includes a flexible support having first and second major surfaces, an extruded fluoropolymer layer overlying the first major surface, and a cast or skived fluoropolymer layer overlying the extruded fluoropolymer layer. Another grilling belt can include a support having first and second major surfaces, and a first fluoropolymer film overlying the first major surface. The support can include a first fabric having a first bias angle, and a second fabric laminated to the first fabric and having a second bias angle different from the first bias angle by between 20° and 160°.

摘要:
A multilayer construction includes a barrier layer having first and second major surfaces and including a polyimide material, a first outer layer directly bonded to and in direct contact with the first major surface of the barrier layer, and a second outer layer directly bonded to an in direct contact with the second major surface of the barrier layer. The first and second outer layer including a thermoplastic polymer. The first and second outer layers form first and second opposite outer surfaces of the multilayer construction. The construct is prepared using extreme heat lamination.

摘要:
An improved perfluoropolymer composite that uses a blend of a perfluoropolymer (such as PTFE) and a silicone polymer. By coating a substrate, such as glass fiber fabric, with a blend of a perfluoropolymer and a silicone polymer, an adhesive layer can be bonded either directly to the surface of the perfluoropolymer composite or to a perfluoropolymer composite that has been primed without the need to have otherwise treated the perfluoropolymer surface, such as either by etching or by the deposition of an intermediate coating containing colloidal silica or other similar agents, to make the surface bondable.
摘要:
In an embodiment, a method includes determining a path between a power source and a tie switch in a feeder within a model of a power distribution network. The method also includes determining one or more ratings respectively associated with one or more transformers located on the path. The method also includes determining one or more loads respectively associated with the one or more transformers located on the path. The method also includes determining one or more available capacities respectively associated with the one or more transformers based, at least in part, upon the one or more ratings and the one or more loads respectively associated with the one or more transformers. The method also includes assigning an available capacity to the tie switch in the model based, at least in part, on the one or more available capacities respectively associated with the one or more transformers, such that the model indicates how much power may be supplied by the feeder, upon activation of the tie switch, to restore power to a portion of the power distribution network.
