Abstract
Heating elements, electrical devices and processes for manufacturing these components are provided. The heating elements and electrical components employ a fibrous support layer, such as a non-woven glass mat, which provides structural support to the relatively thin cross-section of the electrical device or resistance wire when a polymeric layer is applied.
Claims7
A method of making an insulated, electrical component, comprising:
- providing an electrical device having a relatively thin cross-section, which is susceptible to distortion during encapsulation by a liquid or semi-liquid polymeric composition;
- adhering said electrical device onto a fibrous support layer;
- and encapsulating said fibrous support layer and said electrical device within a polymer layer comprising said polymeric composition, whereby said fibrous support layer provides structural support to said relatively thin cross-section of said electrical device to minimize distortion or dislocation during said encapsulation.
