Copper tube is made to EN 1057 standard and coated in plastic.
Plastic coated copper tube is useful for:
Identification purposes:
Plastic can have UV stabilisers added if used outside.
Instructions for use:
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:
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%
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.
