Hey there! As a supplier of peek tubing, I often get asked about the storage requirements for this awesome material. So, I thought I'd put together this blog post to share everything you need to know.
First off, let's talk a bit about what peek tubing is. PEEK stands for Polyether Ether Ketone, and it's a high-performance thermoplastic known for its excellent mechanical properties, chemical resistance, and biocompatibility. That's why it's widely used in various industries, including medical, aerospace, and automotive.
Now, onto the storage requirements. The way you store your peek tubing can have a big impact on its performance and lifespan. Here are some key factors to keep in mind.


Temperature
Temperature is a crucial factor when it comes to storing peek tubing. PEEK has a relatively high glass transition temperature (around 143°C or 289°F) and a melting point of about 343°C (649°F). However, it's still important to store it at a stable and moderate temperature.
Ideally, you should keep your peek tubing in an environment where the temperature ranges between 20°C and 25°C (68°F and 77°F). Avoid exposing it to extreme heat or cold, as this can cause the material to expand or contract, which may lead to dimensional changes or even damage.
For example, if you store peek tubing in a hot warehouse where the temperature can reach over 30°C (86°F) during the summer, the tubing may become soft and lose its shape. On the other hand, if it's stored in a cold environment, say below 0°C (32°F), it can become brittle and more prone to cracking.
Humidity
Humidity is another important consideration. PEEK is a hygroscopic material, which means it can absorb moisture from the air. While it doesn't absorb as much moisture as some other plastics, excessive humidity can still affect its properties.
You should aim to keep the relative humidity in the storage area between 40% and 60%. High humidity can cause the tubing to absorb water, which may lead to swelling, reduced mechanical strength, and changes in its electrical properties. Low humidity, on the other hand, can make the tubing dry and brittle.
To control humidity, you can use dehumidifiers or humidifiers in the storage area, depending on the local climate. Also, make sure the storage space is well-ventilated to prevent the buildup of moisture.
Light Exposure
Peek tubing should be stored away from direct sunlight and other sources of UV light. UV radiation can cause the material to degrade over time, leading to discoloration, loss of mechanical properties, and reduced chemical resistance.
If possible, store your peek tubing in a dark or shaded area. You can also use opaque containers or covers to protect it from light. This is especially important if you're storing the tubing for an extended period.
Contamination
Contamination can also be a problem when storing peek tubing. The tubing should be kept clean and free from dirt, dust, chemicals, and other contaminants.
When handling the tubing, make sure your hands are clean, and use appropriate gloves to avoid leaving fingerprints or other residues. Store the tubing in a clean and sealed container to prevent dust and debris from getting in.
If the tubing comes into contact with chemicals, it's important to clean it immediately to prevent any chemical reactions that could damage the material.
Packaging
Proper packaging is essential for storing peek tubing. The tubing should be packaged in a way that protects it from physical damage, moisture, and light.
Most peek tubing is supplied in plastic bags or tubes, which provide a basic level of protection. However, if you're storing the tubing for a long time, you may want to consider using additional packaging materials, such as bubble wrap or foam inserts, to cushion the tubing and prevent it from getting scratched or dented.
You can also label the packaging with important information, such as the type of tubing, size, and storage instructions, to make it easier to identify and handle.
Types of Peek Tubing and Their Specific Storage Needs
There are different types of peek tubing available, each with its own specific characteristics and storage requirements. Let's take a look at some of the common types:
Green Peek Tubing
Green Peek Tubing is often used in medical applications due to its biocompatibility and chemical resistance. When storing green peek tubing, it's especially important to maintain a clean and sterile environment.
In addition to the general storage requirements mentioned above, make sure the storage area is regularly cleaned and disinfected. If the tubing is intended for medical use, it should be stored in a way that complies with relevant medical regulations and standards.
Peek Capillary Tubing
Peek Capillary Tubing is very thin and has a small internal diameter. This makes it more delicate and prone to damage.
When storing peek capillary tubing, be extra careful to prevent it from getting bent or kinked. You can use special holders or reels to keep the tubing straight and organized. Also, make sure the storage container is large enough to accommodate the tubing without causing it to be compressed or deformed.
Peeksil Tubing
Peeksil Tubing combines the properties of PEEK and silicone. It has a unique combination of flexibility and chemical resistance.
When storing peeksil tubing, pay attention to the temperature and humidity requirements. Silicone can be more sensitive to temperature changes than PEEK, so make sure the storage environment is stable. Also, avoid exposing the tubing to sharp objects that could cut or damage the silicone layer.
Conclusion
In conclusion, proper storage of peek tubing is essential to maintain its performance and lifespan. By following the guidelines mentioned above, you can ensure that your peek tubing remains in good condition and is ready for use when you need it.
