Every medical-grade plastic has properties that may be similar to other polymers but what sets them apart is their 'biocompatibility'. When a plastic material is biocompatible, it is compatible with living tissue and does not cause any toxic or immunological response when exposed to the body.
In addition to being biocompatible, Medical Plastics should be malleable, hard, precise, and compatible with injection moulding and 3D printing processes.
Plastic polymers have inherent properties such as durability, chemical resistance, and heat resistance. They can thus withstand continuous sterilisation, making them suitable for the manufacture of medical components.
