1. High Mechanical Strength
Powdered PEEK insulation has great mechanical strength. Its unique molecular structure gives it toughness. In high - performance machinery with vibrating and impacting parts, PEEK - made components stay intact. It often has over 90MPa tensile strength, outperforming many regular insulators. This strength ensures durability in normal use and reliable operation in harsh mechanical conditions.
2. Good Densification and Uniformity
When processed, Powdered PEEK insulation can be well - densified. Hot pressing and injection molding evenly compact it. The final product is highly uniform. PEEK molecules are evenly spread, so properties are consistent throughout. Whether for electrical or mechanical aspects, there are few variations. Good densification also makes it more resistant to moisture due to fewer voids.
3. Excellent Electrical Insulation
Powdered PEEK insulation has outstanding electrical insulation. It can block electrical currents across a wide frequency range. With a dielectric constant of 3.2 - 3.3, it reduces energy loss in electrical transmission. Its 17 KV/mm breakdown voltage allows it to withstand high - voltage fields. An arc resistance of 175V shows its good insulation. It's perfect for electrical and electronic applications like high - voltage connectors and circuit boards.
4. High Temperature and Corrosion Resistance
Powdered PEEK insulation resists high temperatures well. With a 343℃ melting point and 143℃ glass transition temperature, it keeps its properties under heat. It can be used long - term at 260℃ and endure short - term exposure to 300℃. It hardly decomposes even at 400℃ briefly. It also resists many organic solvents, oils, weak acids, and alkalis, except concentrated sulfuric acid. So, it's suitable for extreme environments like chemical plants with high heat and corrosive substances.
