Abstract
Methods of cyclically heating and cooling an article formed of a static dissipative ETFE resin, such as to reduce an electrical resistivity and/or to increase a tensile strength of the article, and methods of irradiating an article formed of a static dissipative ETFE resin, such as to increase a tensile strength of the article. Also disclosed herein are articles formed of a static dissipative ETFE resin, and processed in accordance with methods disclosed herein. Such an article may include, for example and without limitation, a cable strap to wrap, support, and/or secure one or more wires or cables, such as a cable tie.
Claims20
A method, comprising:
- heating a cable strap formed of a static dissipative ethylene tetrafluoroethylene (ETFE) resin to a first temperature within a range of approximately 150° Celsius and a melting point of the resin;
- cooling the cable strap to a second temperature;
- and
- repeating the heating and the cooling of the cable strap until an electrical resistivity of the cable strap is reduced.
An apparatus, comprising:
- a plurality of cable straps formed of a static dissipative ethylene tetrafluoroethylene (ETFE), each cable strap including a substantially smooth edge surface, wherein an average electrical resistivity of the substantially smooth edge surfaces, measured between two points that are approximately six inches apart, is less than approximately 50 mega Ohms.
A cable strap formed of a static dissipative ethylene tetrafluoroethylene (ETFE) resin, and subsequently subjected to repeating heating and cooling cycles between a temperature within a range of approximately 180° Celsius and 200° Celsius, and an ambient temperature.
