WHY CHOOSE OUR ULTRA-FINE PEEK WIRE?
We specialize in solving interconnect challenges where conventional materials fail. This ultra-fine wire is not merely a smaller gauge option; it is a feat of materials engineering. By utilizing PEEK—a polymer whose properties rival specialty ceramics—we provide a wire that can survive soldering processes, endure proximity to high-heat components, and resist aggressive chemicals, all while being flexible enough for intricate harnessing. It is the definitive choice when reliability cannot be scaled down with size.

FAQ
Q1: What are the typical AWG size ranges for this ultra-fine PEEK wire?
A: This technology is typically applied to very fine conductors, often in the range of AWG 30 to 44 (approximately 0.255mm² down to 0.0020mm² conductor cross-section). The ultra-thin yet tough PEEK insulation allows for an exceptionally small overall diameter.
Q2: How does PEEK's flexibility compare to PTFE at this scale?
A: While both are flexible, PEEK offers superior "flex-life" and resistance to cut-through or abrasion compared to PTFE at similar diameters. This makes it more durable during installation and in high-vibration applications, despite PTFE having a slightly lower initial bend force.
Q3: Is this wire suitable for soldering directly?
A: Yes, the PEEK insulation has an extremely high melting point (~343℃) and excellent thermal stability, allowing it to withstand hand or reflow soldering processes without melting, shrinking, or degrading, provided standard soldering temperatures and times are observed.
Q4: Can it be used in vacuum or outgassing-sensitive environments?
A: Absolutely. PEEK is known for very low outgassing properties. Specific grades can be selected to meet stringent outgassing standards like NASA's ASTM E595 (commonly TML <1.0%, CVCM <0.1%), making it ideal for satellite and vacuum chamber use.
Q5: Do you offer custom colors for the PEEK insulation?
A: Yes, while natural PEEK is typically tan/brown, we can provide custom colored PEEK insulation (e.g., red, blue, yellow, green) for color-coding within complex micro-harnesses, using thermally stable pigments that do not degrade PEEK's performance.
