(PTFE, referred to as F4), which has the advantage of high temperature long-term use temperature of 200 ℃ does not melt does not burn, low temperature below -100 ℃ is still soft; corrosion resistance to water (water) Sulfuric acid) and organic solvent; high insulation volume resistance of 1018 ohm.cm, and dielectric properties almost independent of temperature and frequency changes; high lubrication with plastic in the smallest static friction coefficient; no adhesion of solid materials in the smallest surface Tension and no adhesion of any material; set hot is not bad, resistant to all kinds of acid and alkali media and has excellent anti-aging performance advantages in one, bright colors, smooth appearance, long service life. The disadvantage is that fluoride material production costs are too high, it is difficult to spread in the market a lot.


   Silver-plated wire, with good electrical conductivity, and bright and shiny surface, and silver layer has a high corrosion resistance and can make the coating within the copper material to prevent oxidation. Because of these advantages, making its silver-plated high-purity oxygen-free copper wire provides unparalleled audio resolution, making high-purity no-noise accurate high-speed transmission equipment. It is suitable for the machine signal cable, audio amplifier power line between the signal line, the power cord, the overall sound quality has a certain role in the promotion of high fidelity, high resolution, rich details, sound balance.
