Description for PTFE Wrapping Wire (AFR250):
One of high temperature wires,One of Teflon wires.
Silver plated copper conductor PTFE wrapping tape insulated Teflon Wire.
Advantage and product features of PTFE wrapping wire：
High temperature resistance 260℃
Corrosion resistance,chemical resistance
Oil resistant，strong acid-resistance， strong alkali-resistance，oxidant-resistant.
Moisture-resistance, flame-retardant，
Anti-ageing, the longest aging life among all the plastic wires.
Strong tensile strength,excellet mechanical property
Outstanding advantage comparing with PTFE extruded teflon wire:
PTFE wrapping wire is lighter than PTFE extruded teflon wire type.
Explanation of PTFE telfon wire types: 250℃ High temperature Wire
Two types as per different manufacturing ways:
● AFT250: PTFE Extruded insulation production
● AFR250: PTFE wrapping insulated production for teflon wire,this kind insulated teflon wire is lighter than extruded PTFE wire,but wrapping insulated PTFE wire can also resist 250℃ high temperature.
AFR250 is for PTFE Wrapping Wire,it is lighter than AFT250(PTFE extruded teflon wire type)
Difference for PTFE extruded insulation wire and PTFE wrapping tape insulation
wire: Wrapping tape PTFE wire is more lighter than extruded PTFE wire,OD is a little smaller than PTFE extruded teflon wire.
