WIRE & CABLES
Applications
Cables cover a wide range of high and low voltage applications, under-the-ocean as well as for house-hold requirements. Low water absorption also plays an important part because of its link with the ultimate long-term insulating properties.
Stabiliser Requirements
Stabilisers giving high electrical resistance and low energy dissipation are crucial for safe power transmission.
Stabiliser formulations can be adopted to suit the requirements of high speed extrusion in production and ultimately the final wire & cable applications:
- outer sheathing: good thermal and mechanical stability in combination with other formulation additives
- wire insulation: high thermal stability in the presence of the metallic wire (often copper) and excellent electrical insulation properties balanced with lubrication to satisfy demanding in-service temperatures.
- thin wall sheathing:
high output with good surface finish necessary for telephone cable etc.
This requires enhanced performance from the stabiliser.
Additional special, global requirements from certain large user groups like the automobile industry have to be met as well (e.g. leadfree).
