Key PEEK Polymer Properties for Seals

Thermal Resistance

PEEK is a strong plastic that handles high heat well. It keeps working even in temperatures up to 250°C (482°F). This makes it useful in industries like cars and airplanes. These industries need materials that can handle heat stress. For example, Ketron 1000, a common type of PEEK, works great in such conditions.
PEEK seals do not break down easily from heat. They last a long time in tough environments. Unlike other plastics, PEEK stays strong even with harsh chemicals like nitric acid at high heat. Its ability to handle heat makes it perfect for jobs needing steady performance.

Chemical Stability

PEEK seals are great at resisting many chemicals. This makes them very useful in places with corrosive materials. PEEK stays strong when exposed to acids like acetic acid, hydrochloric acid, and ammonia. It also resists solvents like acetone and methanol, making it last longer.
Some chemicals, like methylene chloride or DMSO, may cause slight swelling in PEEK. But overall, its chemical resistance is still excellent. For example, PEEK can handle sodium hydroxide at 100°C (212°F) without breaking down. This makes it reliable in industries like oil and gas, where strong chemicals are common.

Mechanical Strength

PEEK is very strong and works well under pressure. It can handle a lot of stress without breaking. PEEK seals keep their shape and work well even under long-term stress. This is because they resist creeping or deforming over time.
PEEK also resists wear and tear, making it good for high-friction jobs. It is both strong and flexible, which helps it last in tough conditions. These features make PEEK seals a top choice for engineering and manufacturing.
 
PEEK seals also handle repeated stress without wearing out. This means they last a long time, even in machines that move a lot. Whether in factory tools or car systems, PEEK seals work reliably every time.

Low Friction and Wear Resistance

PEEK seals work great where low friction is needed. Their smooth surface helps parts move easily, saving energy. This makes them perfect for machines with moving parts. Less friction means less damage and longer-lasting parts. PEEK seals are reliable in fast or high-pressure settings.
 
PEEK seals last longer than many other materials. They resist damage even on rough surfaces or in tough conditions. For example, in spinning parts, PEEK seals stay strong despite constant use. This strength means fewer replacements, saving time and money.
 
PEEK seals work well with or without lubrication. Their low friction stays the same in both cases. This makes them useful in many industries, like cars and factory machines. Choosing PEEK seals helps machines run smoother and last longer.
Tip: Use PEEK seals in high-friction areas to make machines last longer.

Longevity in Harsh Environments

PEEK seals are made for tough conditions. They work well in extreme heat, strong chemicals, and high pressure. Whether in oil rigs or airplanes, PEEK seals are very durable.
 
They handle tough environments without losing performance. For example, PEEK seals work in temperatures from -70°C to 250°C (-94°F to 482°F). This means they can be used in freezing or hot places without failing.
 
PEEK seals also resist damage from strong chemicals. They stay strong even when exposed to acids, solvents, or oils. This makes them a good choice for industries using harsh substances daily.
 
PEEK seals can handle sunlight and moisture, so they work well outdoors. Their toughness keeps equipment running longer with fewer problems. Using PEEK seals lowers repair costs and improves efficiency.
Note: PEEK seals are a great option for industries needing durable solutions in hard conditions.
