PEEK pepper ball and Teflon pepper ball are two kinds of pepper balls commonly used in automobile industry, aviation industry, military industry and other industries. Although they are both pepper balls, there is a great difference between the two kinds of pepper balls. Here, the characteristics of the two kinds of pepper balls are compared.PEEK pepper balls have the above advantages:◆ PEEK pepper ball self-lubrication has low friction coefficient, which can realize oil-free lubrication and can work in oil, water, steam, weak acid and alkali for a long time.◆ PEEK pepper balls are easy to process, and parts can be directly processed by injection molding process. It can be used for post-processing such as turning, milling, drilling, tapping, bonding and ultrasonic welding.◆ PEEK pepper balls are low-smoke and non-toxic, and the amount of smoke and toxic gas is particularly low when burning.◆ PEEK Pepper Ball is high temperature resistant. The UL certification of the United States has a long-term use temperature of 260℃. Even when the temperature reaches 300℃, it can still maintain excellent mechanical functions.◆ PEEK Pepper Ball Wear-resistance In many extremely harsh use environments such as high temperature, high load and strong corrosion, PEEK compound and its composite materials have excellent wear-resistance function.◆ PEEK pepper ball has the best mechanical strength among plastics. At the same time, it also has high rigidity and surface hardness.◆ PEEK pepper balls are corrosion-resistant and insoluble in common solvents, and have good corrosion resistance to various organic and inorganic chemical reagents.◆ PEEK pepper balls are resistant to hydrolysis. When soaked in steam with temperature over 250℃ or in high-pressure water, PEEK products can still work continuously for thousands of hours without obvious functional decline.◆ The electrical function of PEEK pepper ball can still maintain stable and excellent electrical function in a wide temperature and frequency range.Teflon pepper balls have the above advantages:◆ Teflon pepper balls are resistant to high temperature-the working temperature reaches 250℃.◆ Teflon pepper ball is resistant to low temperature-it has good mechanical toughness; Even if the temperature drops to -196℃, the elongation of 5% can be maintained.◆ Teflon pepper ball is corrosion-resistant-inert to most chemicals and solvents, resistant to strong acid and alkali, water and various organic solvents.◆ Teflon pepper balls are weatherproof-they have the best aging life among plastics.◆ Teflon pepper ball is highly lubricated-it has the lowest friction coefficient among solid materials.◆ Teflon pepper ball does not adhere-it is the smallest surface tension in solid materials and does not adhere to anything.◆ Teflon pepper ball is non-toxic-it is physiologically inert, and it has no adverse reaction when implanted into the body as an artificial blood vessel and organ for a long time.◆ Teflon pepper ball electrical insulation-can resist 1500 volts high voltage electricity.
