Thick-walled and robust shrink tubing with thermoplastic inner adhesive, extremely resistant to mechanical stresses, solvents, acids, and alkalis. Due to the high shrink rate, the tubing easily adapts to large diameter differences and reliably protects against moisture and other environmental influences. Packed in a sturdy display carton, each TREDUX tubing is identified by a label with EAN barcodes. Due to its high load capacity and weather resistance, this heat-shrink tubing is particularly suitable for use in the ground and under high mechanical loads.
