An Introduction to Biocompatible Plastics

Biocompatible Plastics

From blood tubing to heart valves, biocompatible plastics have become omnipresent in the medical device industry. There’s a reason recent years have seen significant advances in pacemakers, joint replacements and stents: The advanced properties of specialty plastics have made these innovations possible.

Why have specialty plastics brought about a golden age of medical devices? Namely, these biocompatible plastics offer strength, malleability and chemical inertness impossible with traditional metals. It’s also possible to manufacture these devices at lower cost than traditional metals, though plastic devices often last longer and perform better. In short, the golden age of biocompatible plastics has only just begun.

(It’s worth noting, too, that medical-grade plastics are better suited to resisting corrosion from frequent disinfectants than metals, another reason for plastics’ growing dominance in medical environments.)

We machine custom plastic parts for clients in a wide range of industries. In this blog, we’ll share some information about biocompatible plastics that pass testing procedures issued under ISO 10993 or the USP Class VI.

Choosing A Biocompatible Plastic

What is biocompatibility? Biocompatible plastics enhance healing functions without causing toxic or allergic reactions. They’re able to do so because of their chemical inertness; they don’t interact with the environment of the human body, enabling the body to accept these devices without ill effect.

When it comes to assessing biocompatibility, medical devices are categorized as one of the following:

Based upon their categorization, materials must undergo testing of their chemical, thermal, mechanical and other properties.

Materials may be further categorized by length of time they will spend in contact with the human body. Based upon this specification, these are just a few examples of biocompatible plastics that often meet industry standards:
