FEP shrink tubing is available in a range of sizes and dimensions to accommodate various applications and requirements.
The specific sizes and dimensions may vary between manufacturers, but here are some common options:
Diameter: FEP shrink tubing typically comes in a variety of diameters, ranging from small diameters like 0.8 mm (0.03 inches) to larger diameters such as 50 mm (2 inches) or more. The diameter determines the size of the tubing when fully shrunk.
Wall Thickness: FEP shrink tubing is available in different wall thicknesses, typically specified in millimeters or inches. The wall thickness affects the durability and insulation properties of the tubing.
Length: FEP shrink tubing is often supplied in standard lengths, such as 1 meter (3.28 feet) or 4 feet (1.22 meters). However, custom lengths can also be obtained based on specific requirements.
Shrink Ratio: FEP shrink tubing has a specific shrink ratio, which indicates the amount of shrinkage it undergoes when heated. Common shrink ratios for FEP tubing range from 1.3:1 to 4:1, meaning the tubing will shrink to a fraction of its original size when heated.
It’s important to note that the availability of sizes and dimensions may vary depending on the manufacturer or supplier. It’s advisable to check with the specific supplier or manufacturer for the exact range of sizes and dimensions available for FEP shrink tubing. Additionally, some manufacturers may offer custom sizes or provide the option for custom fabrication based on specific application needs.
What are the main properties and characteristics of FEP shrink tubing?
FEP shrink tubing, made from fluorinated ethylene propylene, possesses several key properties and characteristics that make it suitable for various applications.
Here are the main properties and characteristics of FEP shrink tubing:
Temperature Resistance: FEP shrink tubing exhibits excellent temperature resistance, with a high continuous service temperature ranging from approximately -200°C (-328°F) to 200°C (392°F). It can withstand extreme cold and heat without degradation, making it suitable for applications in both cryogenic and high-temperature environments.
Chemical Resistance: FEP shrink tubing has exceptional chemical resistance, making it compatible with a wide range of corrosive chemicals, solvents, and acids. It resists attack from most organic and inorganic chemicals, allowing it to be used in aggressive chemical environments.
Electrical Insulation: FEP shrink tubing offers excellent electrical insulation properties. It has a high dielectric strength and low dielectric constant, making it suitable for applications that require reliable electrical insulation, such as wire harnesses, electronic components, and insulation sleeves.
Transparency: FEP shrink tubing is transparent, allowing for easy visual inspection of the underlying components or connections. This transparency is advantageous in applications where visual monitoring or quality control is necessary.
Low Friction Coefficient: FEP shrink tubing has a low coefficient of friction, which enables smooth wire or cable insertion and removal. It reduces the risk of damage to delicate wires and facilitates easier installation and maintenance.
Non-Stick Surface: FEP shrink tubing has a non-stick surface, similar to other fluoropolymer materials. This property makes it resistant to adhesion and buildup of materials, reducing the risk of contamination or clogging. It also simplifies cleaning and maintenance.
Flexibility: FEP shrink tubing is flexible and can be easily bent and shaped without kinking or collapsing. Its flexibility allows for easy installation and conforming to irregular shapes or tight spaces.
UV Resistance: FEP shrink tubing exhibits good resistance to ultraviolet (UV) radiation, making it suitable for outdoor or exposed applications where prolonged exposure to sunlight or other sources of UV radiation is expected.
It’s important to note that these properties and characteristics may vary slightly between different manufacturers or specific grades of FEP shrink tubing. It’s advisable to consult the manufacturer or supplier for detailed technical specifications and to ensure that FEP shrink tubing is the appropriate choice for a specific application.
