PI tube polyimide tube

Product Description:

Thermoplastic polyimide (TPI) is a polymer material with excellent properties. It is widely used in medical, nuclear power and other fields due to its high temperature resistance, low temperature resistance, solvent resistance, radiation resistance and other properties.

Polyimide (PI) is an organic polymer material with excellent comprehensive properties. It can withstand high temperatures above 400°C. It has a long-term use temperature range of -200~300°C. It has no obvious melting point and has high insulation performance. It is an F to H class insulating material. Sleeves of this material have good electrical, physical and mechanical insulation properties. The casing has significant radiation resistance and flexibility at extremely high and low temperatures.

Features:

1) Good dimensional stability, the accuracy can be stabilized at ±0.03mm, and the tube wall thickness is 0.05mm-0.5mm.

2) Good heat resistance and thermal insulation, no brittleness at low temperature, and can be used for a long time at 250℃.

3) Good insulation performance, dielectric strength not less than 300kv/mm.

4) Good mechanical properties, tensile strength not less than 150MPa, tensile elongation not less than 10%.

5) Good chemical resistance, resistant to most solvents except strong acid and alkali solutions.

6) Good sterilization properties, can withstand various disinfection methods such as ethylene oxide, high temperature and high pressure, and irradiation.

7) Strong bonding properties. After surface treatment, the material can have good bonding strength with metals and other materials.

Application areas:

As a pipe with geometric dimensions, electrical, mechanical and precision, it can be used in small space, harsh high and low temperature environment, complex electromagnetic and radiation environment and other use conditions, such as organisms and underground, nuclear power plants, industrial facilities, instruments and equipment, etc., as protective casing, insulating casing, gas and liquid conduit, etc.

It is suitable for various medical catheters, including nerve catheters, implantable catheters, cardiac catheters, etc. Due to its high temperature resistance, it has advantages in processing and high temperature preoperative treatment. Because of its better mechanical properties and chemical stability, it is suitable for more complex medical processes, such as catheters that remain in the body for a long time.

Application examples:

Thermistor insulation sleeves, electronic probe sleeves, temperature sensor sleeves, electric heating element sleeves, precision conduits for high-temperature corrosive liquids and gases, etc.
