tubing and films since 1969
Multi wall spiral wound tubes and endcaps are used in various thermal and electrical insulation applications also to ensure an excellent chemical protection.
These tubes are chosen also for their higher mechanical strenght and perforation 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 multi wall 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.
