Thin-walled heat shrink tubing with adhesive RTCK12/3 RTCK-12/3

Heat shrink tubing with adhesive – reliable protection for wires and cables

Heat shrink tubing RTCK12/3 is a high-quality solution for securing wires and cables, made of polyolefin (PO-X) with built-in hot melt adhesive. It provides effective protection against moisture and corrosion, and its versatility makes it suitable for many electrical and electronic installations. Thanks to the adhesive, the connection is not only mechanically stable but also waterproof – particularly important in harsh environmental conditions.

Construction and properties

Made of polyolefin, the tubing is characterized by flexibility and abrasion resistance. A shrinkage ratio of 4:1 allows it to be adapted to various wire and cable diameters – from 2.5 mm² to 35 mm². After shrinking, the inner diameter decreases from 12 mm to 3 mm, and the wall thickness is 1.95 mm. This model is thin-walled, making it easier to use in confined spaces. Additionally, the tubing is halogen-free, which increases safety and minimizes the risk of toxic gas formation in the event of a fire. The ability to print allows for easy identification of cables and wires after shrinking.

Applications and benefits

• Moisture protection: Hot melt adhesive provides excellent waterproofness of the connection, protecting against corrosion and damage caused by water.
• Electrical insulation: Polyolefin provides good insulating properties, increasing the safety of the installation.
• Versatility: A wide range of wire diameters (2.5 - 35 mm²) and a high shrinkage ratio (4:1) allow for use in various applications.
• Wide operating temperature range: The tubing retains its properties at temperatures from -45°C to +125°C, allowing it to be used both indoors and outdoors.
• Easy identification: The ability to print facilitates the marking of cables and wires after shrinking, which improves servicing and maintenance of the installation.
• Compliance with standards: It has a UL certificate, confirming the high quality and safety of the product.
• Safety: Halogen-free material minimizes the emission of toxic substances during a fire.

The length of the tubing is 1.22 m, allowing many connections to be secured with one piece of material – saving time and costs during assembly! The black color provides good visibility and an aesthetic appearance of the installation.
