Medium-wall and thick-wall heat-shrink tubing

Heat-shrink tubing differs in various properties – one essential criterion is the wall thickness. Depending on the application, thin-, medium- or thick-wall variants are used.

What is medium-wall heat-shrink tubing?

Medium-wall heat-shrink tubing has wall thicknesses of approx. 1.5 mm to 3.0 mm after shrinking. It is made of high-quality polyolefin and is optionally available with hot-melt adhesive. Due to its greater wall thickness, it is particularly suitable for applications with increased mechanical stress. Medium-wall heat-shrink tubing is available from BIT up to a diameter of 410 mm.

• BPMW – medium-wall heat-shrink tubing made of polyolefin
• BPMW A – with adhesive coating
• BPMW M – with mastic coating

What is thick-wall heat-shrink tubing?

With a wall thickness of approx. 3.0 mm to 5.0 mm after shrinking, thick-wall heat-shrink tubing is the most robust variant. It offers excellent mechanical protection but is less flexible than thin-wall tubing. It is ideal for outdoor applications or under high stress.

• BPTW – thick-wall heat-shrink tubing made of polyolefin
• BPTW A – with adhesive coating
• BPHW A – with adhesive and 6:1 shrink ratio

Applications

• Cable connections in mechanical and plant engineering
• Automotive and shipbuilding
• Outdoor applications with increased environmental stress
• Electrical insulation and sealing
