Introduction
PEEK stands for Polyether Ether Ketone. It’s a strong, heat-resistant plastic known for its ability to work well in harsh conditions.
Today, more healthcare manufacturers are choosing PEEK. One reason is that it’s biocompatible, meaning it works safely inside the body.
According to MarketsandMarkets, the global PEEK market is expected to grow from $1.5 billion in 2025 to $2.14 billion by 2030. Medical use is one of the major factors behind this growth.
Why PEEK Works Well in Medical Applications
PEEK has a unique mix of features that make it useful for medical devices and implants.
Biocompatibility
Biocompatibility means a material can be safely used inside the human body without causing harm.
PEEK is often used in spinal implants, bone screws, dental healing caps, and more. It’s non-toxic and doesn’t cause reactions like inflammation, which is essential for patient safety.
Durability and Resistance
PEEK resists wear, chemicals, and repeated sterilization. This makes it reliable for devices that are reused, such as surgical tools.
It also holds up in chemical cleaning agents and harsh environments, keeping its shape and strength over time.
High-Temperature Stability
Medical equipment often needs to be steam-sterilized at high temperatures. PEEK can tolerate heat up to 260°C (500°F) without melting or warping.
This is a major reason why it’s used in reusable surgical instruments and device housings.
How the Industry Uses PEEK
PEEK is becoming more common in both permanent implants and disposable medical parts.
Here are some areas where it’s used:
- Spinal fusion cages
- Bone plates and fixation screws
- Catheter components and tubing
- Dental implants and caps
- Reusable surgical instruments
Companies like Medbio, as referenced in their MD&M East showcase, are leveraging PEEK in high-precision injection molding to meet regulatory needs and product demands for Class I, II, and III medical devices.
Conclusion
PEEK is a trusted material in modern healthcare. Its biocompatibility, toughness, and heat resistance make it an excellent option for advanced medical devices.
As the need for safe, long-lasting materials grows, PEEK will likely play an even larger role in hospitals, labs, and clinics.
