With the rapid development of modern medical technology, medical catheters, as an important medical device, are widely used in various minimally invasive surgeries and diagnostics. In order to improve the performance of catheters and patient comfort, new materials and technologies are constantly introduced into the catheter manufacturing process.
Teflon tube, also known as PTFE tube, is a very special material that is a polymer formed by polymerizing tetrafluoroethylene as a monomer.
From the appearance, the PTFE tube appears white waxy and semi transparent. Its heat and cold resistance are simply amazing, making it a leader in the materials industry.
It can stably exert its performance even in extreme temperature environments. This material also has a significant feature, which is that it does not contain any pigments or additives, maintaining the most authentic state of the material. Because of this, it has excellent acid resistance, alkali resistance, and resistance to various organic solvents.
In almost all solvent environments, PTFE pipes will not dissolve, and PTFE's high temperature resistance is also outstanding. Its friction coefficient is extremely low, which makes it perform excellently in some application scenarios that require reducing friction.
Chemical resistance: PTFE tubing has extremely high resistance to most chemicals, making it highly reliable when transporting drugs or chemical reagents.
Low friction coefficient: The low friction coefficient of PTFE reduces internal friction in pipelines, helping to reduce losses during transportation and lowering maintenance costs.
Biocompatibility: The biocompatibility of PTFE tubing allows it to be safely used inside the human body without causing adverse reactions.
High temperature tolerance: PTFE tubing can withstand temperatures up to 260 ° C and is suitable for medical environments that require high-temperature disinfection.
Advantages of PTFE lined pipe HEYSON
1. Improve the wear resistance and service life of the catheter
Traditional catheters are prone to friction and wear during use, while the low friction coefficient and high wear resistance of PTFE etched tubes can significantly reduce friction and improve the service life of the catheter. At the same time, the PTFE surface after etching treatment is more durable and resistant to damage and wear.
2. Enhance biocompatibility and reduce inflammatory response
PTFE material itself has good biocompatibility, and the etched PTFE surface can better bond with biological tissues, reducing the body's rejection and inflammatory reactions to the catheter. This is particularly important for catheters that are placed in the body for a long time, as it helps to improve patient comfort and safety.
3. Anti adhesion and mechanical properties
PTFE conduits have lower surface energy, reducing the attachment of biological substances such as bacteria and platelets, and lowering the risk of infection and thrombosis; It can be more easily combined with other materials, such as coating drugs, antibacterial coatings, etc. At the same time, the unique structure of PTFE etched tubes enables them to maintain flexibility while possessing better mechanical properties.
