Description

ATW is a halogen free, RoHS, flame retardant tubing designed for application in closed and sensitive environments such as trains, ships and in underground mining where the formation of acid gas after fire must be minimised to avoid consequential damage to computers, PC’s and electronic control equipment. Being RoHS compliant means the product does not contain restricted substances such as Cadmium (Cd), Lead (Pb), Hexavalent Chrome (Cr6) and Mercury (Hg). RoHS is now a requirement in the automotive industry.

 

Features

  • Cross-linked polyolefin
  • Shrink Ratio 2 : 1
  • Operating temperature – 55 to 125°C
  • Excellent flame retardance VW-1
  • Colours – Standard colours, green/ yellow stripe and clear
  • Minimum shrink temperature 70°C
  • 600V
  • Black – UV Stable

Applications

  • Quick recovery at low temperatures makes it ideal for use in electronics and telecommunication applications
  • RoHS coupled to flame retardant properties makes this product suitable for use in automotive harnesses
  • Ships, trains and underground mining
  • Any enclosed areas which contain sensitive electronic equipment and computers
