The serial of NFT heat shrinkable sleeve with radiation
cross-linking low-temperature shrinkable non-fire resistant
The scope of using the serial of NFT
The serial production of NFT was wildly applied for the trade of electric power, etc,main used for harness protection, lead sign, insulation protection of welding point, antiseptic pipeline, etc.
The characteristic of the serial of NFT
Contractibility rate 2:1
Shiny surface, bright color, soft production, easy operation
Continuing using temperature -30°C—105°C
The lowest complete shrinkable temperature 90°C
Possessing several colors:black,red,yellow,blue,green,white,gray and transparent |
