Autoclaving (Steam)

Autoclaving uses hot steam under pressure to clean tools. PET heat shrink tubing works well with autoclaving. This is because PET can handle heat and water. The tubing can take up to 135°C for a long time. It can also take up to 200°C for a short time. This means you can use it many times in labs and hospitals.

Best ways to use autoclaving are:

• Use the right heat and pressure.

• Let the tubing cool before you touch it.

• Do not put too much in the autoclave.

Some things cannot take heat or water. But PET heat shrink tubing keeps its shape and strength after many uses. This makes it good for tough jobs.

Gamma Radiation

Gamma radiation is a way to clean things without heat. PET heat shrink tubing works well with gamma radiation. PET does not melt or change shape from the radiation. It keeps its strength and does not lose its good features.

Tests show:

• PET tubing stays strong and bends well after many uses.

• Numbers like p-values ≤ 0.05 and < 0.001 show gamma radiation works well to keep PET safe and clean.

• PET is better than Nylon 6.6, which gets weak and stiff.

• PET tubing can be cleaned many times for medical tools.

The tubing may turn a little yellow, but it still works fine. Gamma radiation is good for things that cannot take heat or water.

Ethylene Oxide (EtO)

Ethylene oxide uses gas at low heat to clean things. PET heat shrink tubing works well with EtO. PET does not get hurt by the gas and stays bendy. EtO can clean hard-to-reach places and tubing without damage.

Best ways to use EtO are:

• Make sure to air out the tubing after cleaning to get rid of gas.

• Watch how long and how much gas you use.

EtO takes more time than other ways. But PET tubing stays strong and keeps its insulation. This is good when heat or water would cause trouble.

Chemical Sterilization

Chemical sterilization, like hydrogen peroxide vapor, is gentle. PET heat shrink tubing works well with chemicals because PET does not get damaged. The tubing keeps over 88% of its strength after 50 cleanings with hydrogen peroxide. It does not get bigger, smaller, or lose insulation.

Tips for best results:

• Rinse the tubing well if needed.

• Follow the maker’s rules for how much chemical to use.

Chemical cleaning is good for soft or heat-sensitive things. Be careful with leftover chemicals so you do not leave any behind. PET’s resistance to chemicals helps it last a long time and stay safe.

Methods to Avoid

Incompatible High-Temperature Methods

Some ways to sterilize things use heat that is too high for PET heat shrink tubing. These ways can hurt the tubing and make it not work well. Dry heat sterilization and burning can get much hotter than PET can take. If PET gets too hot, it might melt, bend, or get weak.

⚠️ Important: Always check how the tubing works in real sterilization before using it.

People who work with medical devices know there are risks with using too much heat:

• The tubing can break down, which makes devices unsafe.

• Devices might not work if the tubing fails during or after cleaning.

• There could be delays and higher costs if products need to be fixed or recalled.

• ISO 17665-1:2023 says materials must not break down during sterilization.

• FDA Quality System Regulations and ISO 10993 say you must test for safety and cleaning.

• Not testing and checking can make products unsafe and cause failed checks.

PET heat shrink tubing keeps over 88% of its strength after 50 times using hydrogen peroxide cleaning. This shows it is strong when you pick the right way to clean it.

Other Unsuitable Techniques

Some ways to clean are not good for PET heat shrink tubing, even if they do not use high heat. For example, dry heat ovens, open flames, and microwaves can heat unevenly or be hard to control. These ways can make some parts too hot and hurt the tubing or not clean it all the way.

Other bad ways include:

• Strong chemicals like bleach, which can break down the tubing.

• Too much UV light, which can make the tubing brittle or change color.

• Scrubbing too hard, which can scratch or thin the tubing.

Picking the right way to clean keeps the tubing and device safe. Following the rules and testing helps make sure everything works well every time.
