Advantages and Common Applications of PEEK Plastic Material Components

Advantages of PEEK plastic material components

PEEK plastic material is a high-performance engineering thermoplastic with unique characteristics. This rigid substance belongs to the family of polyether ketone polymers and is one of the most widely used and often mass-produced polymers. Polyetheretherketone is a highly processable semi-crystalline thermoplastic with excellent heat resistance, mechanical strength, and chemical resistance. In addition, its polymer structure has excellent environmental resistance, dimensional stability, and mechanical strength. PEEK plastic material has extremely strong biodegradation resistance. Parts, products, and implants made from Polyetheretherketone can reliably continue to be used for a very long time unless actively recovered or disposed of.

Common uses of PEEK plastic material

Polyetheretherketone has many types and grades, some of which are more suitable for specific uses than others. Due to polyetheretherketone's physical properties, it can be used in a wide range of industries, including bearings, piston parts, aerospace materials, medical prosthetics, etc., and its application volume is increasing every year.

Due to the numerous advantages enjoyed by PEEK plastic material, it has become the preferred material for many challenging environments. Industries that utilize polyetheretherketone include medical, oil and gas, aerospace, food and beverage, and others.

Common parts and products made from polyetheretherketone include: bearings and bushings, automotive components, semiconductor machinery, food processing equipment, piston parts, pumps, high-performance liquid chromatography columns, compressor plate valves, cable insulation, medical prosthetics and implants, vacuum cleaners and valves, safety pliers, dental instruments.

Comparison between PEEK, PEK, and PTFE

When a material that can withstand harsh high-temperature environments is needed, the best choice is usually narrowed down to PEEK, PEK, and PTFE. We already know that PEEK plastic material is a rugged semi-crystalline thermoplastic with high resistance to many harsh environmental factors.

PEK (polyether ketone) is a ketone-based, semi-crystalline high-performance thermoplastic with excellent thermal dimensional stability, low flammability, strong chemical resistance, and mechanical properties over a wide temperature range that are almost consistent at temperatures 30 degrees higher than standard polyetheretherketone. Combined with solid creep resistance and fatigue resistance, these characteristics give it unique properties that most other polymers do not have.

PTFE (polytetrafluoroethylene) belongs to the family of fluorinated polymers, and the presence of fluorine makes it highly electrically, chemically, and acid-resistant. Its mechanical properties are lower than those of other polymers, but its flexibility at low temperatures is considered a key feature. PTFE is stable at temperatures up to 260°C. PTFE is commonly used for support rings and special seals. It is also used for electrical insulation, isolation, and low-friction bearing parts. In addition, high-purity grades of PTFE are commonly used for fluid handling systems in the semiconductor industry.
