best PFA coated insulation wire manufacturer
what is PFA stranded wire?
PFA wire is one of the Teflon electrical wires, PFA is named Perfluoroalkoxy, It can be used for a long time at 250 degrees Celsius, its flame retardant is VW-1, not easy to burn, and immediately extinguished after leaving the flame. The conductor is tinned copper, which will also not break immediately after combustion. When encountering fire, it will not produce toxic and harmful gases, making it safer and more reassuring to use. The insulation layer made of PFA has higher continuous use temperature and better stress cracking resistance than FEP or PTFE! PFA wires and cables are widely used in the fields of high-frequency data transmission cables, connecting wires for key parts in the automotive industry, network cabling in the construction industry, and drilling cables in the petroleum industry.
Differences between PFA wires and FEP, ETFE, and PTFE wires
- Different temperature resistance, PFA 250 degrees, FEP 200 degrees, PTFE 260 degrees, ETFE 150 degrees.
- The production and processing temperatures are different: the PFA of about 385 degrees and the FEP of about 350 degrees.
- Different specific weight: PFA has a slightly higher specific weight.
- PFA has excellent crack resistance and stress resistance.
- PFA has good penetration resistance and the product is more stable.
- PFA wires have higher bending resistance.
