Kynar PVDF (property of Arkema) is a high purity polymer that combines extreme-temperature performance, easy manufacturability, and durability in some of the harshest environments.
What is PVDF?
PVDF (polyvinylidene difluoride or polyvinyl fluoride) is a fluorinated thermoplastic resin that is classified as a specialty polymer whose brand names include Kynar (Arkema), KF (Kureha), and Solef or Hylar (Solvay). This engineering polymer can often be found in environments that involve high purity, hot acid, extremely high temperatures, and/or radiation.
Selecting the right rotary shaft seal for a medical application involves many different factors including sanitation and sterilization concerns, material compliance to both national and international standards, and patient safety. While some medical applications still depend on elastomeric sealing solutions, FDA-approved PTFE rotary shaft seals provide far more benefits.
There are many factors that contribute to the rapidly growing medical plastics market. There is an increased demand for advanced medical devices, a rise in disposable income and changing lifestyles, and a demand for affordable and efficient healthcare systems.
These and more are currently driving the medical market, with a current estimated net worth of 22.8 billion USD.
And it is only growing.
Experts suggest that by 2024, the market will grow to a whopping 31.7 billion, with a CAGR of 6.8%.
Plastic packaging is widespread across many industries, but no more so than in the medical field. Within the next few years, packaging is expected to grow at a CAGR of 7.8%, due to the increased use in pharmaceutical packaging, device packaging, and more.
Surprisingly though, it is devices such as medical implants and machinery that are generating the largest revenue and driving the industry forward. A perfect storm of an ever-growing population and an increase in chronic diseases, along with the lower manufacturing cost of these devices has led to the largest growth in the medical plastics industry.
Since the 1980s plastics have dominated the medical device industry on account of their low manufacturing cost, flexibility, ease of replacement, and low risk of infection.
Plastics also provide radiolucency, enable light-weighting, and reduce stress-shielding. Because they are radiolucent, polymer-based surgical devices allow surgeons to have an unobstructed view.
All these combine to make medical-grade plastics the gold standard in the industry. Which in turn creates a very lucrative market.
The medical-grade plastic industry has taken off in an incredibly short amount of time. With increasingly easy to manufacture products coupled with an ever-expanding market, the industry will only get bigger over time. Want to learn more? Contact us today!
Due to the COVID-19 pandemic, there has been an increase in worldwide demand for thermal scanners, respirators, and ventilators. This has been accompanied by an increased need for medical disposables such as gloves, respirators, medical masks, face shields, single-use syringes, and drapes. As a result, medical engineering and manufacturing both have temporarily shifted their focus and the results are fascinating.
Shortages of some items have led to innovative design and manufacturing, much of it involving additive manufacturing using polymer materials. For example, Old Dominion University has been 3D printing masks and mask components made from PLA and designed so that they can be easily sterilized and reused. Europe has already seen companies in the 3D printing industry volunteer their equipment and knowledge to aid in manufacturing replacement parts for critical equipment such as oxygen and respirator valves, and many other countries are doing the same thing.
Many countries, including the United States, are worried about a potentially deadly shortage of ventilators. Various technology firms worldwide such as Nvidia are working to design critical care devices that can be produced both quickly and inexpensively. NASA has been given permission to start production of their emergency use ventilator that can be manufactured and built quickly, with the only drawback being its limited lifespan.
In addition, ventilator manufacturers such as Medtronic have ramped up production and publicly shared their design specifications for one of their ventilator models so others can help meet this critical need.
Engineers all over the world are looking for ways to make the treatment of COVID-19 patients easier and safer for medical personnel. For example, engineers in the Boston area have teamed up local doctors to develop a 3D printed bracket that will hold the tube and respirator hookup together in ventilator patients. The goal is to prevent release of the COVID-19 virus into air when these connections come undone, as they often do.
Others at Boston University are looking at polymer nasal swabs that will do a better job of collecting mucus for COVID-19 tests, which could increase the reliability of testing and help with testing material shortages. At the Oxford Institute of Biomedical Engineering, engineers are leveraging wearable technology to allow nurses to track the vitals of COVID-19 patients who are not on ventilators and thus must remain mobile to recover.
The COVID-19 pandemic has changed how much of the world lives, and has affected a shift in the focus of many engineers. Trademarks of this shift include the use of additive manufacturing for PPE and replacement parts for life-saving equipment, a fresh look at ventilator designs that emphasizes manufacturability and availability, and the birth of innovative approaches to medical issues related to the pandemic. And, in this midst of this, companies like Advanced EMC are still working hard to make available the right polymer seals and bearings needed for medical equipment.
