Politubes offers a complete range of heat-shrinkable polyester tubes – available in spiral or “double cigarette” versions – specifically designed for the protection of refrigerator coils, static condensers, and heat exchangers.

Key advantages

The use of heat-shrinkable polyester ensures higher efficiency, operational reliability, and cost reduction:

• Rolls up to 1,000 meters: reduced setup times and increased productivity, especially in automated processes.
• Perfect adaptability: the tube conforms to and maintains the shape of the coil.
• Fast application: quick positioning and heat-shrinking process.
• Superior mechanical strength: extended durability and maximum protection against mechanical stress.
• Advanced protection: high resistance to puncture, chemical agents, and gases, as well as excellent condensation shielding.
• Compact design: reduced bulk thanks to the low thickness.
• Sustainability: materials fully compliant with environmental regulations, REACH and RoHS.
• Functional transparency: allows continuous visual inspection of the coil condition.

Adhesives, carefully selected through over 40 years of experience, ensure preservation of the film’s original properties and full regulatory compliance.

Technical specifications

• Available diameters: from 4 to 25 mm
• Thickness: from 75 to 150 microns
• Supply formats: pre-cut to required length or in rolls of several hundred meters, optimizing logistics and reducing transport costs.
