Polyurethane (PUR) - Thermoplastic Elastomer

Polyurethane has become increasingly important in the cable industry over the past years. This material shows at certain temperatures mechanical characte­ristics similar to rubber. The combination of thermoplastic and elastic characte­ristics has led to the description TPE  thermoplastic elastomer.

Mechanical characteristics

The insulation materials of the cables are usually not subject to high mechanical stress. Sheaths, on the other hand are heavily used. This is especially true for flexible control and connection cables which are often pulled over sharp corners and rough surfaces. This can lead to cuts which are accentuated when the cable is stretched during flexible use. Compressive stress caused by squashing and impacting from tools and machines can also occur. The most important mechanical characteristics of PUR are:

High tensile strength

High tear resistance

Notch resistance

Abrasion resistance

Alternate bending resistance

Impact resistance

Flexibility at low temperatures


Chemical characteristics

The chemical resistance depends upon many factors such as chemical type, reaction time, temperature, volume, concentration and of course the type of Polyurethane used. In comparison with many other materials, such as rubber or PVC, PUR has a better resistance against chemical reaction. The outstanding chemical characteristics are:

1 Hazardous substances-Free: Directive 2015/863/EU

2 Oil resistance: EN 60811-2-1

3 Microbe Resistance: DIN VDE 0282

4 Chemical & Hydrolysis resistance: DIN53504

5 Paint wetting impairment substances resistant

6 Thermal range:-40℃to +85℃

7 Great Flexibility
