JUNHUA PI-MT Tube

With the adjustment of the company’s development strategy and the changes in the market environment, we are pleased to announce that the company’s new medical PI capillary products have been officially launched on the market.

JUNHUA®PI-MT is a polymer material with excellent performance. It is widely used in medical intervention and other fields due to its high temperature resistance, low temperature resistance, solvent resistance, radiation resistance and other characteristics.

Polyimide (PI) is an organic polymer material with excellent comprehensive performance. It can withstand high temperatures of more than 400°C, has a long-term use temperature range of -200 to 300°C, has no obvious melting point, and has high insulation performance. It belongs to F to H grade insulation materials. The casing of this material has good electronic, physical and mechanical insulation properties. At extremely high and low temperatures, the casing has significant radiation resistance and flexibility.

Medical capillary JUNHUA®PI-MT is our new commitment to product quality and medical industry standards. This brand not only represents our pursuit of excellence, but also reflects our emphasis on medical safety.
To ensure the safety and reliability of JUNHUA®PI-MT medical capillary in the medical field, we conduct a series of rigorous biological tests to ensure that it meets the usage standards of customers and the market.

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 tube with geometric dimensions, electrical, mechanical, and precision, it can be used in small spaces, harsh high and low temperature environments, complex electromagnetic and radiation environments, etc. JUNHUA®PI-MT catheters are suitable for various medical catheters, including nerve catheters, implanted 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.
