    Selection and implementation of PET tubing

    Sizing and fit

    When you pick PET heat shrink tubing, size is important. The tubing should cover your device tightly but not squeeze it. First, measure the widest part of your device. This helps you choose the right tubing size. You also need to know the shrink ratio. The shrink ratio shows how much the tubing gets smaller when heated. Some common shrink ratios are 2:1, 3:1, and 4:1. These ratios help the tubing fit well for safety and insulation.

    1. Measure the widest part of your device.

    2. Choose PET heat shrink tubing using your measurement and the shrink ratio.

    3. Make sure the tubing fits tight but not too tight or loose.

    4. Check the shrink ratio to see how much it will shrink.

    You can use this table to help you pick:

    Property

    Value

    Shrinking temperature

    70°C (158°F)–190°C (374°F)

    Recommended temp

    150°C (302°F)

    Target shrink ratio

    1.1:1

    Optimal fit

    15% gap or less

    Pick PET heat shrink tubing with an expanded diameter just bigger than your device. The recovered diameter should be smaller than your device for a tight fit. This helps keep devices safe and works well for catheters and surgical tools.

    Compliance and sterilization

    You must follow rules when using PET heat shrink tubing in medical devices. These rules make sure the tubing is safe and works well in the body. You need to check if the tubing meets standards like ISO 10993, USP Class VI, and FDA Title 21. These rules show that PET heat shrink tubing is safe for surgery and for use in the body.

    Regulatory Standard

    Description
