摘要:
A thermally self-regulating elastomeric composition and heating element made therefrom. The composition includes a body of elastomeric material in which is distributed electrically conductive particulate material, such as carbon black. Short fibers are also distributed in the elastomeric matrix. In the disclosed invention, the short fibers are present in the amount of approximately 0.5 to 20 volume percent. In one alternate form, the matrix is foamed. Different arrangements of the electrodes in electrical conductive association with the thermally self-regulating elastomeric body are disclosed. Preferred proportions and characteristics of the particulate conductive material and short fibers providing optimum thermally self-regulating characteristics of the composition are disclosed.
