Developed as a modular system for the continuous expansion of heavy wall tubing in the range of 12 - 200 mm (expanded diameter) with wall-thickness ranging from 2.0 - 6.0 mm. Depending on the size, quality and consistency of the crosslinked tubing, speeds of 3 - 4 m/minute or even higher can be achieved.
The expansion line consists of the following major modules:
Expanded sizes from 5 mm up to 50 mm (expanded inside diameter). The IR machine will expand 2:1 and 3:1 thin and medium wall heatshrinkable tubing. Speeds of up to 12 m/minute, depending on size, compound composition and consistency of the crosslinked tubing.
The PTL/Compo flattening line is for flattening heat-shrinkable tubing to be used as identification sleeves. This line is capable of flattening expanded heat-shrinkable tubing of multiple diameters ranging in diameter from 2.4mm up to 76.2mm.
Consistent flattening can be easily achieved. The flattener has been designed and equipped with controls for product consistency and reproducibility.
Halogen-free and halogenated, flame-retardant polyolefin heat-shrink tubing in 2:1 and 3:1 shrink ratio, as well as other heatshrinkable tubing (such as fluoropolymer based products) can be easily flattened to any desired ‘puff’.
The PTL range includes various commercial polyolefin compounds for thin wall applications, and special compounds for high grade applications including defense. Also compounds for medium- & thick-wall tubing for low voltage and medium voltage up to 36 kV are available.
