Spiral wound Heat shrink - Non shrink Insulation tubes and sleeves

Multilayers spiral wound tubes and endcaps are used in various thermal and electrical insulation applications also to ensure a higher mechanical resistance and chemical protection.

Thanks to our multi layers spiral wound technology, we are able to combine different type of films  inside a single tubular or endcaps.

The result is somehow unique also because the combinations of layers are always specially customized for our customers.

Spiral-wound consists of pairing a series of tapes coated with adhesive, rolling them up in a spiral around a spindle.
The product obtained has a tubular shape and incorporates all the technical features found in each of its components; in the second step of manufacturing the product is turned into tubes or caps with different seals.

 

Spiral-wound sleevings offer a superior electrical and thermal and insulation in many components.

 

The technology employed by Politubes enables them to produce bespoke coiled tubes with a myriad of features specifically requested by the client: thickness between 0,05 and 0,7 mm, diameters from 1,8 to 155 mm and coloring to name a few.

 

They can be supplied cut in lenght ( from 6 mm till 14.000 mm ) or rewound in rolls - spools of several hundred meters.


Our tubes end endcaps may have the following seals:

 

1. Spiral-wound heat - non heat shrink, AHS , 2LSO tubes or endcaps
2. Ultrasonic welded spiral-wound endcaps
3. Ultrasonically spot-welded spiral-wound endcaps
4. Bullnose spiral-wound endcaps
5. Spiral-wound semi-caps

 


Politubes Research and Development team are more than happy to receive your requests for a specific criteria.
