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)
