PVC Coated Copper Tubes

The Plastic that we are using for the tube coating is a Low Density Polyethylene along with a World Wide UV stabiliser.

The Physical properties are as follows:

Mechanical

Melting point: 114°C

Vicat Softening Point: 93°C (This can be generally treated as the maximum operating temperature)

Brittleness Point: < -75°C

Hardness: 55 Shore D

Tensile Break: 13.40 MPa

Flexural Strength: 8.10 MPa

Elongation at Break: 500%

Electrical

Volume Resistivity: >1015 Ohm-cm³

Surface Resistivity: >1015 Ohm -cm²

This range is ideal for use within walls, outside, underground and in aggressive atmospheres. The covering creates a thermal barrier reducing heat loss underground and condensation from exposure in extreme weather conditions. Tubes are pecifically made in 5.8m lengths for direct loading and shipping in full containers.

Tubes can withstand temperatures from -40 to +120 degrees centigrade.
Tubes can be bent (except 35-54mm) and jointed as per standard plain EN1057 tubes using EN1254 fittings.
To expose bare copper, plastic coating needs to be cut and pulled back away from the joint and flame (if brazing). Once joint has been made coating needs returning back to original position and both joint and cut need to be protected using an impervious plastic tape.
