For medical plastics suppliers and suppliers of mold and extrusion services to medical device manufacturers, there is some good news recently: According to the latest report, the global disposable medical products market will be on the right track in the next decade. Strong growth. The medical market research firm said that in the past two decades, the global disposable medical supplies market has grown at an average annual rate of 12.5%.
Due to contact with the drug solution or contact with the human body, the basic requirements of medical plastics are chemical stability and biosafety. Simply put, the composition of plastic materials can not be precipitated into the liquid or human body, does not cause toxicity and damage to tissues and organs, and is non-toxic and harmless to the human body.

The market for disposable medical plastic products will continue to grow
Typical materials used in disposable medical supplies, from syringes to surgical kits, include PVC, PP, PE, thermoplastic elastomers, and PCs. Because of the lower cost, medical device designers are trying to replace metals and glass with plastics that offer similar properties, so the demand for such plastics and other polymers in the medical market will continue to grow.
