Q: Applications of PTFE tubing
A: Medical PTFE tubing is a highly versatile material that has a variety of applications in the medical industry. Its unique properties make it the go-to material for many applications that require precision, durability, and chemical resistance. Here are some of the applications of medical PTFE tubing:
1. Catheters: Medical catheters usually require a flexible and durable material that can withstand the rigors of repeated insertion and removal. PTFE tubing exhibits excellent flexibility and resistance to wear and tear, making it the ideal material for catheters.
2. Endoscopes: Endoscopes are used for diagnostic and therapeutic purposes, and they require a tubing material that is flexible, smooth, and non-reactive. PTFE tubing is ideal for this application due to its bio-compatible nature and smooth surface that ensures easy flow of fluids.
3. Implantable Devices: PTFE tubing is often used in the manufacture of implantable devices, such as vascular grafts, heart valve replacements, and artificial joints. It is bio-compatible, non-toxic, and does not elicit an adverse reaction when implanted in the human body.
4. Laboratory Equipment: Medical PTFE tubing is used extensively in laboratory equipment such as chromatography columns, sample preparation devices, and pumps. Its chemical inertness, high temperature tolerance, and low friction make it an ideal choice for these applications.
5. Drug Delivery Systems: The use of PTFE tubing in drug delivery systems is becoming increasingly popular due to its non-reactive nature with most pharmaceuticals. PTFE tubing is ideal for use in intravenous drug delivery systems, and other implantable drug delivery devices.
6. Dental Equipment: PTFE tubing is widely used in dental equipment such as syringes and tips. Its non-reactive nature with dental materials ensures patients do not experience any adverse reactions.
In conclusion, medical PTFE tubing has a broad range of applications in the medical industry. Its unique properties make it ideal for critical medical applications that require precision, durability, and chemical resistance. With increasing research and technological advancements in the medical industry, it is expected that the use of PTFE tubing will continue to grow, with its applications growing even more diverse.
7.Medical PTFE tubing is also extensively used in the production of ultrasound probes, as it can withstand high temperatures and is highly resistant to chemicals. Its excellent electrical insulation properties make it an ideal choice for transmitting signals that are necessary for live monitoring.

Q: PEEK corrosion resistance
A: 1. PEEK can tolerate almost any chemical except smoke concentrated sulfuric acid, even at higher temperatures, it can still maintain good chemical stability. It has strong chemical corrosion resistance and is usually used to manufacture parts that work in harsh environmental conditions or need to undergo frequent disinfection treatment (such as chemical storage tanks, medical devices that require disinfection with strong oxidant hydrogen peroxide).
2. Although PEEK polymer has been widely considered as a kind of material can withstand strong chemical corrosion, of course, the PEEK specific resistance to some corrosive medium and PEEK parts crystallinity, internal stress residue and parts contact by the medium temperature, concentration also have related, specific please check the following table (because the file is larger, please download view):
3. Chemical corrosion resistance characteristics of PEEK are divided into the following three categories:
A: No erosion, trace amount or no absorption;
B: Minor erosion, applicable depending on the application;
C: Severe erosion and cannot be used in the presence of these chemicals.
