Heat Shrink Tubing
Applications
All Medical Devices
Vesta’s ExtruMed™ precision medical extrusion solutions optimize the clinical outcome of thin wall polyolefin heat shrink tubing for the medical device industry.
Function
Protective Covers, Reflowing Sleeves, Tube Splicing/Joining, Metal Wire, Tube and Rod Insulation, Catheter Strain Reliefs, Manufacturing Aids
Vesta’s medical heat shrink tubing possesses excellent concentricity, flexibility and thin-wall construction. High shrink ratios allow for ease of use, excellent fit, compliance and thin recovered walls.
Description
Heat Shrink Tubing Will Recover to a Smaller Diameter When Exposed to Heat
Vesta understands the nuances of thin wall heat shrink tubing. We provide medical device design assistance to help you define the minimum expanded inner diameter, the maximum recovered inner diameter, recovered length requirement and the recovered wall thickness to ensure optimal performance.
Technology
Extrusion, Irradiation and Expansion Process
Vesta uses a three-step process to manufacture heat shrink tubing: extrusion, crosslinking and expansion. We use materials such as LDPE, MDPE and LLDPE (low-, medium- and linear low-density polyethylene), manage and control crosslinking with our preferred outsourced partner, and conduct the expansion process using our custom-designed expansion equipment.
Competency
Ultra-Thin Walls and High Expansion Ratios
Vesta’s experienced staff ensures high concentricity, proper radiation dosages and a tight expansion process to manufacture the most challenging medical heat shrink tubing. Our expertise includes:
- Expanded ID 0.01"–0.3" (0.25 mm–7.62 mm)
- Expanded wall thicknesses as thin as 0.0003" (0.00762 mm)
- Shrink ratios as high as 10:1
- Rapid and low recovery temperatures
- Length: 0.5"–60" (1.2 cm–150 cm), continuous length available for some sizes
- Colors: clear or customer-specified
