Introduction of 1. PTFE plate, tube and rod
With the continuous development and progress of modern science and technology, domestic polytetrafluoroethylene and other chemical materials also bring us more surprises with the continuous progress of technology, such as "polytetrafluoroethylene
Enene plate, tube, rod "all bring a lot of convenience to our daily life! A more prominent performance, PTFE in medical equipment materials also have amazing effect. Below, I
We understand the advantages of polytetrafluoroethylene in medical treatment.
Blood vessels are biological transport of blood pipes, throughout the body, mainly composed of arterial blood vessels, venous blood vessels and capillaries. Arterial vessels from the heart, constantly branching, mouth
The diameter gradually becomes smaller, and finally it is divided into a large number of capillaries, which are distributed to the tissues and cells of the whole body.
We all know that people in the case of massive bleeding, a long time will lead to death, so the transport and protection of blood vessels is extremely important. Blood vessels closely with all parts of the body
Connected, the blood is transported from the heart to the whole body, and then transported back to the heart by the whole body, infinite circulation, in order to maintain the normal physiological function of the person. If a person's blood vessels are diseased or
Destruction, has a fatal impact on human life.
Therefore, modern scientists continue to study, trying to find a product that can replace blood vessels, in human vascular lesions and necrosis, instead of blood vessels to protect people's blood is
Often transport, to maintain human life. In the end, they found the answer. As a kind of physiologically inert and harmless to the human body, PTFE has become an artificial blood vessel and dirty
The main material of the device has a good integration with the human body, even if it is long-term implantation, there will be no adverse reactions.

2. new grade a material polytetrafluoroethylene rod and medical use difference
new grade a material ptfe rod is shenzhen dankai science and technology limited company in many products more popular. As most of the plastic products of industrial raw materials application range extremely
Its wide range and high market demand make the price of PTFE rods rise steadily in the new year, but don't think that PTFE rods only play a major role in plastic products.
In fact, it has good performance in many fields, and PTFE products can also be used in the medical industry.
The following is an analysis of the difference between the new grade A material and medical use of PTFE rod.
In fact, there is not much difference between ordinary and medical polytetrafluoroethylene rods. The difference between medicine and ordinary is mainly due to the different production links and needs of many products in the production process.
The difference in the scale of PTFE rod manufacturers has a greater impact on the production of products. Generally, small manufacturers will have problems in the production process and the production environment.
Not up to standard production equipment is not advanced enough, so the production of polytetrafluoroethylene contains impurities and toxic substances, and medical polytetrafluoroethylene rod is to prevent harmful substances
Yes, therefore, medical polytetrafluoroethylene rods must be produced by large enterprises. In addition to judging whether the product parameters can meet the standards, the most important thing is to check them when selecting them.
Certification manufacturers, to see whether the production environment and details meet the requirements, in strict accordance with medical standards to test the performance of the product can be clearly distinguished.
Teflon rods can make some artificial organs, such as heart bypass catheters are made of it. Of course, we can also choose countries when selecting medical Teflon rods.
Imported raw materials, such as Daikin in the United States and DuPont in Germany.
Characteristics of 3. PTFE rods
The special properties of PTFE rods mainly include corrosion resistance, insulation resistance, high and low temperature resistance, self-lubricating, surface non-stick, and atmospheric aging resistance.
Specific introduction.
Excellent corrosion resistance-can withstand all strong acids (including aqua regia), strong oxidants except molten alkali metals, fluorinated media and sodium hydroxide above 300 ℃,
The role of reducing agents and various organic solvents.
Strong insulation resistance-not affected by the environment and frequency, the volume resistance can reach 1018 ohm? cm, the dielectric loss is small, and the voltage is high.
Excellent high and low temperature resistance-little change in temperature, wide temperature range, usable temperature -190 ℃ and 260 ℃.
Unique self-lubrication-with the smallest coefficient of friction in plastics, it is an ideal oil-free lubricating material.
Outstanding surface non-stick-known solid materials can not adhere to the surface, is a solid material with the smallest surface energy.
Excellent resistance to atmospheric aging, radiation resistance and low permeability-long-term exposure to the atmosphere, the surface and performance remain unchanged. The valuable incombustibility --- the oxygen limit index is 90.
