However, the excessively high torque caused by today’s higher speeds can result in severe wear, and even cracking within a short period of time. For years, the material of choice for gears in low-speed copiers was POM (polyacetal), and for medium to high-speed copiers was PPS (polyphenylene sulfide). ►Copier and printer speeds have increased significantly in recent years, placing harsh demands on structural components such as fuser roller gears. ►Ease of Processing - processing flexibility makes it ideal for use in a wide variety of applications. Has excellent resistance to acids, bases, salts and steam. ►Chemical Resistance -insoluble in all common solvents. ►Wear Resistance Without Lubrication - outstanding wear resistance coupled with a low coefficient of friction-essential in key printer parts such as bushings and gears. Unfilled grades have a tensile strength of 16,000 psi carbon filled grades have a tensile strength of 33,800 psi. ►Excellent Mechanical Properties - maintains impact strength, stiffness, and minimum levels of creep. Essential for the fusing section of laser printers. Heat resistance up to 260☌ (500☏) - highest of all thermoplastics. ►Outstanding Thermal Performance - excellent dimensional stability and tolerance control across a broad range of temperature and humidity conditions. It can withstand continuous operating temperatures of up to 260☌ (500☏), and delivers exceptional mechanical strength and higher wear and torque resistance. PEEK polymer is a high performance thermoplastic with a unique combination of properties. The drive towards multi-functional, high speed, color printing/copying devices has revolutionized the printer/copier market and fueled manufacturers’ demands for robust, flexible, high-performance materials.
