Sintered usually refers to the curing of PTFE, the process of causing a material to become a coherent mass by heating without melting it.
Sintered describes a process, most often referring to PTFE, in which a material is caused to become a coherent, solid mass by heating it without fully melting it. PTFE is applied as a powder or unsintered form and then heated, or sintered, so that the particles fuse together into a dense, continuous material. This is part of how PTFE insulation is finished after it has been formed onto a conductor.
Because PTFE does not melt and flow like ordinary thermoplastics, sintering is the means by which its particles are consolidated into a solid, homogeneous insulation. The sintering step gives the finished PTFE its final properties, including its excellent dielectric and chemical resistance.
In commercial and industrial wire, sintering is part of the production of PTFE-insulated cable used in high-temperature and high-performance applications. Recognizing the process helps in understanding how this premier insulation is finished.
