GDW: Dual Wall Tubing

GDW is dual wall tubing manufactured by co-extrusion of polyolefin and hot melt adhesive. Designed to provide both insulation and sealing for protected articles.

APPLICATIONS :
  • Provides permanent waterproof barrier & environmental seal for electrical components such as wire splices & harness in automobile & communication industry.
  • Used as an alternative to moulded parts and cable breakouts
  • High shrink ratio enables insulation of cables with connectors of various sizes-Suitable for use in telecommunication, industrial equipment, automotive and avionics.
GENERAL PRODUCT PROPERTIES :
  • Shrink ratio 3:1 and 4:1
  • Operating temperature ranges from -550C to +1250C
  • Resistance to weathering and UV rays
  • Chemical, copper corrosion and fungus resistance
  • Dielectric strength of 15kV/mm.
  • Meets RoHS Compliance
  • Meets IP 68 (Ingress Protection)
SPECIFICATIONS :
