Plastic rubber is one of the most important basic materials in modern society, and has been widely used in medical equipment and medical packaging. Since the first use of synthetic polymer materials celluloid membrane as a dialysis membrane artificial kidney in the 1930s, polymer materials have gradually replaced traditional inorganic materials such as metals (or alloys), glass, ceramics, Apatite or the like is used for preparing medical devices, especially in broad-spectrum medical consumables (infusion sets, blood transfusion devices, syringes, etc.), respiratory anesthesia (intubation, respiratory masks, etc.), neurosurgery (skull repair tablets, drainage devices, etc.) ), dialysis, cardiovascular (heart stent, occluder, etc.), etc., have mature and extensive applications.
With the booming industry, a variety of high-performance plastics for medical devices have emerged. The high-performance plastics currently used on the market are traditional products such as PP, PVC, PE, and silicone rubber. For example, the transparent polypropylene (PP) material developed by SABIC has glass-like transparency, which is helpful for conventional or pre-filling. Plastic syringes and metering systems improve metering accuracy and better detect contaminants, and their materials are used to produce medical metering cups. Waker's medical silicone film can be used as a flexible wound dressing, breathable film, or as a dielectric elastomer for sensors and artificial muscles.
In recent years, some engineering plastics have also entered the medical industry with better performance, such as medical grade nylon 12. Compared with traditional medical polymer products, nylon 12 has more excellent biocompatibility, stability, physical and mechanical properties and processing properties, and is now mature in various medical catheters and balloons. For another example, Bayer MaterialScience's insulin pen made of the medical grade polycarbonate blend Baylander M850XF is the same size and shape as the ballpoint pen. It is easy to carry and brings good news to diabetic patients.
Medical device manufacturers are also launching technologies that meet the demand for medical cleanliness. For example, Swiss machine manufacturer Netstal has demonstrated its high-performance solution through an 8+8-cavity production system, producing diameters on an ELION3200-1000 injection molding machine. It is a 90 mm sterilization tray with a production cycle of less than 3.7 seconds and is made of polystyrene. Ningbo Weili Robot Technology Co., Ltd., together with Arburg, Piovan and PassCard in Germany, has created an automated solution for disposable medical products – high-speed extraction of blood collection tubes The packing system better meets the growing demand for clean, non-polluting products in the medical market.
Biomedical materials have also received increasing attention in recent years, mainly for the diagnosis, treatment, repair or replacement of human tissues, organs or to enhance their functions. China's Ministry of Industry and Information Technology's "12th Five-Year Development Plan for New Materials Industry" pointed out that in 2015, it is estimated that 500,000 sets of artificial joints, 1.2 million vascular stents per year, and 1 million intraocular lenses will be needed. The demand for materials, etc. will increase dramatically.
Changes in the medical device market have also brought new opportunities for plastics and rubber. For example, the popularity of wearable medical devices in recent years is inseparable from the participation of various high-performance plastics.
The medical device industry has a typical positive-positive positive cycle characteristic. This feature determines the great potential of the international medical device industry, and the plastic has gained more in the medical field with its excellent properties, reliable performance and convenient molding process. The more widely used. It is predicted that the medical plastics field will be one of the most promising areas of the plastics industry in the next 10 years.
