How do medical multi-lumen tubing help the fight against Covid-19
Amid the Covid-19 virus outbreak, medical PTFE multi-lumen tubing is playing an important part in helping fight the global pandemic. In this article, SuKo will explain what medical tubes are, how they’re used and why they’re helping in the fight against Covid-19.
What are medical tubes?
Medical tubes are used as part of equipment to deliver fluids to and from the body, and can also be used for catheters and respiratory equipment. Some medical tubing should be custom produced with different chambers or cores for delivering medication to the body. Medical tubing has become an essential component in the fight against Covid-19 considering the increased number of ICU patients and the increasing demands for ventilators and other respiratory equipment.
What plastic is used for a medical tube?
PTFE is one of the most commonly selected plastics for medical tubing, because it’s adaptable and can be sterilized. Other types of plastic used in medical grade tubing include more flexible materials such as PVC, TPU, TPE, and TPV, etc.
Sterilization and antibacterial properties of medical tubes
Although single-use plastic is frowned upon in everyday life, it can help prevent the spread of viruses and diseases in the medical profession, which is because it’s more hygienic to dispose of items used to treat those with highly contagious viruses rather than to re-use products.
According to medical tubing companies, medical grade plastics should be able to withstand high temperatures and corrosion for optimum cleaning in places where medical equipment is safe to be sterilized and cleaned. Some medical grade plastics can be fitted with anti-bacterial protection to help prevent the spread of contagious illnesses in hospitals and healthcare environments.
How are medical multi-lumen tubes helping the fight against Covid-19?
Medical multi-lumen tubes, key component of medical devices and respiratory equipment including ventilators which aid breathing, have been used in healthcare for many years to enhance patient care and are critical to patient care in intensive care units. As you know, one of the known symptoms of Covid-19 is shortness of breath, which results from the fact that the virus attacks the lungs and pneumonia and respiratory complications will also occur to people with severe symptoms. Therefore, thin wall medical tubing is helping keep patients affected by the disease alive.

Top 4 Ways to Prevent The Aging of PTFE Tubes
Nowadays, many products stand out in the development of technologies and industry, and best PTFE tube is one of these products that play an important role in various fields. But have you ever noticed the aging of PTFE tubes? The performance of PTFE tubes will also be reduced after aging. So a series of measures should be taken to prevent the aging at the later stage of the production of PTFE tubes. The aging of PTFE tubes is natural and cannot be prevented, but the only thing you can do is to slow the aging speed of PTFE tubes. To help slow down the aging rate of PTFE tubes, you should strengthen maintenance in using PTFE tubes and take a series of measures to prevent this situation. Here Suko offers you the major four methods to slow down the aging speed of your PTFE tube.
1. When choosing the sizing material of PTFE tubes, you should use sulfur curing system whenever possible. Due to the heat resistance of its vulcanized rubber, it can be modified by reducing or avoiding the use of elemental sulfur, which can minimize or remove polysulfide crosslinks and produce mainly monosulfide or disulfide crosslinks, thus slowing down the aging of teflon tubes.
2. To ensure that the material achieves the desired heat resistance, the use of peroxide is required. In this case, peroxide vulcanization produces carbon with better thermal stability and carbon cross-linking bonds. PTFE tube manufacturer also notes that you should pay special attention to other additives in the use of peroxides. For example, the choice of antioxidants needs to be more stringent, as many of them interfere with the vulcanization of peroxides. Therefore, you can also use paraffin oil, an effective additive that will not interfere with peroxide vulcanization.
3. In addition, in order to prevent the partitioning of the peroxide cation and avoid too low vulcanization of the high-pressure hose (indicated by lower hardness, lower modulus and higher compression and long-term deformation), you should use peroxide to reduce the amount of acidic filler. If possible, the addition of alkaline compounds (e.g. zinc oxide or magnesium oxide) usually improves the cross-linking efficiency of the peroxide.
4. When producing best ptfe tubes, some additives can be added, such as antioxidants, and alkaline compounds, etc., so as to improve the cross-linking efficiency of peroxides and delay the aging of teflon tubes.

Expanded PTFE VS. PTFE: What’s The Difference?
You must know PTFE, the father of fluoroplastics. But what is expanded PTFE ? Also known as ePTFE, expanded PTFE is the microporous version of PTFE. ePTFE enjoys similar properties to PTFE. This article will describe the differences between them and their respective applications.
PTFE: the father of fluoroplastics
What is PTFE?
As a polymer compound made of tetrafluoroethylene by polymerization, PTFE has excellent chemical stability and corrosion resistance, and has become one of the materials with best corrosion resistance. PTFE can resist almost all the chemicals, except molten alkali metal, chlorine trifluoride, chlorine pentafluoride and liquid chlorine, so it has been widely used in various occasions to resist acid and organic solvent. PTFE itself is not toxic to people.
Unique properties of PTFE
PTFE is the most unusual fluoropolymer and exhibits the best performance in terms of temperature, chemical resistance and non-stick properties.
● Cost-effective;
● Continuous working at temperature of +260°C;
● Low friction surface;
● Very high electrical resistance.
Applications of PTFE
● According to PTFE manufacturers, PTFE has the following major applications.
● Endure even the harshest of environments and is suitable for use in numerous applications.
● Ideal for use in the food and drink production, including cooking equipment, conveyor belt rollers, non-stick surface covers, and temperature sensor casing.
● Particularly useful for the production of internal and external life-saving equipment.
● Perfect for electrical insulation and protection of electronic components.
● Make different products in the chemical industry, such as gaskets, vessel linings and chemical tanks.
Expanded PTFE: the microporous fluoropolymer
What is expanded PTFE?
Expanded PTFE (ePTFE) is a new type medical polymer material, which is made of polytetrafluoroethylene resin by stretching and other special processing methods. The white, elastic and flexible expanded PTFE has a mesh structure formed through microfiber connection, and these microfibers form countless pores, so that the expanded PTFE can be arbitrarily bent. Its good blood compatibility and biological aging resistance allow it to be used in the manufacture of artificial blood vessels, heart patches and other medical products and become the most ideal biological tissue substitute. With good biocompatibility and unique microporous structure, ePTFE is non-toxic, non-cancerous, and non-allergenic, and will produce no other side effects. Human tissue cells and blood vessels can grow into its micro-pores and then form tissue connections as autologous tissue.
Unique properties of expanded PTFE
Expanded PTFE shares similar properties to PTFE. The material is completely non-toxic and hygienic, and also offers working temperatures up to 260°C. In addition, ePTFE enjoys the following properties.
● Chemically resistant with high linear strength;
● Chemically inert;
● Watertight at low pressure;
● Low dielectric constant;
● Excellent radial expansion and UV resistance.
Applications of ePTFE
1. Medical implants
Purely inert ePTFE can be used in a variety of rehabilitation solutions, including artificial blood vessels and patches for soft tissue regeneration and surgical sutures for vascular, cardiac, general and orthopedic surgery, thereby benefiting both physicians and patients. The ePTFE medical products are able to work in harmony with the body’s own tissues and restore their normal function.
2. Fluorofiber
Expanded PTFE fibers have high strength, low shrinkage, abrasion resistance, and extreme UV resistance, thus ensuring good stability and integrity in extreme environments. This kind of fiber is very versatile and can be woven, spun, braided or sewn into a variety of fabrics, including compression packaging, sewing thread, construction fabrics and dental floss.
3. Gaskets and sealant
