Spiral wound tubing are used for many applications such as electrical insulation, thermal or chemical protection in the electromechanical and automotive fields.
They are also chosen for their superior mechanical properties as they ensure a very high resistance to tearing and best dielectric strength.
The spiraling technique consists in coupling a series of adhesive-coated strips, winding them around a mandrel, obtaining a tubular whose electrical, thermal and mechanical characteristics are the sum of the ones of each layer.
Spiral wound tubing are designed and produced according to customer specifications, heat-shrinkable and not heat-shrinkable according to customer request.
They can be supplied in perfectly round or oval form to facilitate insertion and to reduce the overall dimensions.
Their dielectric strength can reach 303kV/mm with reference to the ASTM-D-149-91 test method and are used within a temperature range between -50°C/+300°C.
Our adhesives, carefully selected during our forty years of experience, comply with all REACH and RoHS regulations and guarantee that the original properties of the films used are fully maintained.
Tubing can be cut according to customer needs or wrapped in rolls up to 1000 meters length.
