Why Choose PEEK for High-Performance Insulating Components

PEEK is a top choice for high-performance insulating components. Engineers appreciate that it is as strong as metal but much lighter, allowing them to create innovative designs and improve fuel efficiency. PEEK resists damage from chemicals and water, making it ideal for demanding environments like oil rigs. It effectively blocks heat and electricity, even under extreme conditions. Manufacturers value its ability to withstand high temperatures and its long-lasting durability. Additionally, PEEK can be easily shaped using methods like CNC machining or injection molding.

Key Properties

Electrical Insulation

PEEK gives great electrical insulation. This makes it a good pick for high-voltage and high-frequency places. Its dielectric strength is 480 V/mil. This is less than Ultem®, but better than many other plastics.

PEEK keeps its insulation even in tough conditions. Its volume resistivity is about 10^16 Ω·cm. Its dielectric constant stays steady from 3.2 to 3.5 at many frequencies. It also has a low dielectric loss tangent at high frequencies. These things help PEEK block electric currents well. It works even with high voltage, pressure, or humidity. Its crystal structure and high thermal stability make it work better as an insulator in hard jobs.

Thermal Stability

PEEK can handle very high temperatures. It can be used up to 260°C. This is the same as PTFE and better than most plastics.

PEEK melts at about 334°C. It stays stiff and strong up to this point. Its special structure with rings and linkages stops it from breaking down in heat. It keeps its shape well and does not change size much when hot. This stops it from warping or bending. PEEK also does not catch fire easily and makes little toxic smoke. This makes it good for planes, cars, and medical tools.

Tip: PEEK’s thermal stability lets it go through many steam cleanings without breaking down. This is important for medical and food uses.

Chemical Resistance

PEEK stands up to many chemicals like acids and solvents. It also works well in wet and steamy places. This makes it good for tough factories where strong chemicals are used.

PEEK resists chemicals better than PPS and Nylon. PTFE is still the best for chemical safety. PEEK can handle acids, solvents, and hot water without breaking down. This helps it last a long time in tough places.

Mechanical Strength

PEEK is strong and stiff but not heavy. This makes it great for things that need to be tough and light. Its tensile strength is 100 to 170 MPa. Its Young’s modulus is between 3 and 4 GPa. These numbers are like some metals, such as aluminum, and much higher than most plastics.

PEEK’s high modulus and strength stop it from bending under weight. It does not slowly change shape when pressed for a long time. Injection molding can make parts with exact sizes. This means parts stay the right size even with heavy use.

• PEEK is strong and stiff, like aluminum.

• It does not slowly change shape, so it stays the same size.

• Its special chemical structure keeps it stable in tough places.

PEEK’s great strength and lightness make it a top pick for high-performance insulating parts. These parts need to handle stress, shaking, and hits.

Material Comparison

PEEK vs. PTFE

PEEK and PTFE are both high-performance insulators. They have different strengths. PEEK is known for its strong build and stiffness. It also handles heat very well. PTFE is best for electrical insulation and chemical resistance. PEEK keeps its shape and strength under heat and heavy loads. PTFE can bend or change shape when it gets hot or is pressed.

PEEK is about five times stronger than PTFE. It can handle hits and does not change shape easily. This makes it good for parts that carry weight. PTFE is not as strong, so it is not used for tough jobs. But PTFE is still the best for electrical insulation.

Note: PEEK costs more than PTFE. It is more expensive because it is harder to make and many people want it. But PEEK lasts longer and works better in important jobs, so the price is often worth it.

PEEK vs. Polyimide

PEEK and polyimide both work well with heat and chemicals. Polyimide can take even higher heat, up to 400°C. PEEK works up to 250°C. Polyimide also stands up to strong chemicals. But it is harder to make and costs more money. Over time, PEEK keeps its strength and insulation better than polyimide. Polyimide can get weaker and lose its good qualities after being in heat and wet air for a long time.

PEEK is easier to make, costs less, and lasts longer. This makes it a good choice for most insulation needs.

PEEK vs. Ceramics

Ceramics can take high heat and do not wear out fast. But they break easily if hit or bent. PEEK can handle heat like ceramics and keeps its size well up to 260°C. PEEK does not crack or break when dropped or hit. It is lighter than ceramics and can be made into many shapes.

PEEK is tough and bends without breaking. This makes it safer and more useful for high-performance insulating parts in hard places.

Applications

Electronics

PEEK is very important in electronics. It helps keep electric parts safe. PEEK Lay-Flat™ tubing lines slots and insulates phases in motors. Magnet wires with PEEK insulation work well in tough places. They do not wear out or get hurt by chemicals. PEEKshrink™ heat shrink tubing covers wire joins and harnesses. Convoluted tubing protects wires and fiber optics from heat. These uses are found in cars, oil and gas, planes, and phone systems.

PEEK is a top pick for electronics. It blocks electricity, stands up to heat, and does not get damaged by chemicals.

Aerospace

Aerospace engineers use PEEK because it works well in hard places. PEEK stays strong and keeps its shape when it gets hot. This is important for planes that face big temperature changes. PEEK does not get ruined by chemicals, water, fuel, or steam. This helps parts last longer and need less fixing. PEEK does not burn easily and makes little smoke. This keeps people safer inside planes. PEEK is light, so planes can be up to 60% lighter than if made with metal. This saves fuel. PEEK also keeps heat and electricity from moving through parts better than metal.

PEEK is used in actuators, controls, and engine parts. Big companies trust PEEK for insulation that lasts a long time.
