What Is PEEK?
PEEK stands for Polyether Ether Ketone. It’s a thermoplastic polymer, meaning it can be melted and reshaped without losing its key properties.
What sets PEEK apart is its exceptional strength, heat resistance, and chemical stability. Because of these qualities, it’s used in high-demand sectors like aerospace, automotive, medical, oil and gas, and electronics.
According to MarketsandMarkets, the global PEEK market is projected to grow from $1.5 billion in 2025 to $2.14 billion by 2030.
The Key Properties of PEEK
Resistance to Heat, Chemicals, and Stress
PEEK holds up well in tough conditions. It can operate at high temperatures (up to 260°C), resists chemical damage, and keeps its strength under mechanical stress. This makes it useful for engine parts, surgical instruments, and electronics.
Long-Term Durability
PEEK doesn’t wear down easily. It resists friction, moisture, and harsh cleaning processes. That means fewer replacements, saving time and maintenance costs in the long run.
How PEEK Is Made and Modified
Processing Methods
PEEK can be shaped using two main techniques:
- Extrusion: Used to create long, uniform shapes like rods and tubing.
- Injection molding: Used to form precise, complex parts for structural or mechanical applications.
These methods help manufacturers produce reliable parts with tight tolerances.
Reinforcement Options
PEEK can be tailored to meet different needs by adding fiber reinforcements. The main types are:
- Unfilled PEEK – pure form, flexible and good for low-load applications.
- Glass-filled PEEK – reinforced with glass fibers for greater stiffness and strength.
- Carbon-filled PEEK – enhanced for even higher strength, better heat resistance, and low friction.
Why Glass-Filled PEEK Leads the Market
Glass-filled PEEK is expected to hold the largest market share by volume, according to MarketsandMarkets. It provides a balance of cost and performance, making it ideal for structural parts like brackets, housings, and electrical components.
Why PEEK Matters
PEEK is valued because it’s:
- Strong in harsh environments
- Stable at high temperatures
- Resistant to corrosion and chemicals
- Adaptable through different shaping methods
- Customizable with reinforcements for added performance
Its combination of strength, safety, and versatility means growing demand across industries—especially where weight, heat, and performance are key concerns.
