There are several grades of plastics that can be used for injection moulding of medical devices and the development of medical device prototypes. Each material has unique properties that determine its performance in the intended application and operating environment. Considerations for selecting the right medical grade plastic material for your medical plastic products include:


1. Strength: Plastic resins provide varying degrees of strength, so it is important to ensure that the medical grade plastic material you choose has the strength properties required for your application.


2.FDA requirements: Medical devices being implanted have different requirements than those used for tubes, medical devices, and other external applications. Before choosing materials, review the FDA requirements for your application.


3. Chemical resistance and heat resistance: When choosing medical grade plastic materials, chemical resistance and heat resistance are two key considerations, especially if your finished parts need to be able to pass autoclaves, gamma rays Or chemically.


4. Operating environment: Operating conditions determine the requirements for strength, temperature resistance, chemical resistance, corrosion resistance, radiation resistance and other factors. Make sure the medical grade plastic material you choose can withstand the conditions of your operating environment.


5. moulding methods: Medical injection moulding and medical insert moulding are two methods commonly used in medical device prototype development, but not all plastic materials are compatible with both methods. Before choosing medical grade plastic materials, it is important to determine which method to use.
