Heat shrink tubing resistant to chemicals
Our assortment includes several types of heat shrink tubing that are resistant to various kinds of chemicals.
Types of chemically resistant heat shrink tubing
We offer three types of heat shrink tubing that are resistant to chemicals. These are made from one of the following three materials:
Each of these materials is resistant to different chemicals:
Kynar® – Characteristics & properties
Kynar® is made from polyvinylidene fluoride (abbreviated as PVDF) and is resistant to chemicals and solvents. This makes Kynar® highly resistant to acids, bases, and solvents. In addition, it withstands high temperatures (up to 175 °C), is very wear-resistant, and offers good UV resistance.
Kynar® is not UV-resistant and not halogen-free. By default, Kynar® is transparent. Our Kynar® heat shrink tubing has a shrink ratio of 2:1.
Viton® – Characteristics & properties
Viton® is a fluoroelastomeer and offers resistance to corrosive liquids, fuels, acids, solvents, and lubricants. It also provides superior wear and cut resistance.
Viton® is self-extinguishing within 30 seconds and is flame-retardant. It can be used at temperatures up to 200 °C and has a minimum full shrink temperature of 175 °C. It is UV-resistant but not halogen-free.
Lastly, heat shrink tubing made from Viton® is always black. The shrink ratio is 2:1.
Teflon® – Characteristics & properties
Teflon® is another name for polytetrafluoroethylene (abbreviated as PTFE). This material is resistant to chemicals due to its low reactivity. As a result, it is widely used in the transport and storage of chemicals. Teflon® is resistant to extreme temperatures, up to 260 °C.
Teflon® is self-extinguishing within 30 seconds and flame-retardant. Our Teflon® heat shrink tubing is transparent and has a shrink ratio of 1.5:1. It meets MIL-SPEC standards. It is not UV-resistant and not halogen-free.
Applications of Kynar®, Viton®, and Teflon® heat shrink tubing
Heat shrink tubing made from one of the materials described above is used in exceptional conditions where high performance is required. These are environments where the tubing is (potentially) exposed to chemicals, extreme temperatures, or where high cut or abrasion resistance is needed.
Personal advice
Due to the specialized applications of Viton®, Kynar®, and Teflon® heat shrink tubing, it can be challenging to determine which type is best suited for your needs. Need tailored advice? Contact one of our specialists—they’ll be happy to assist you.
