The plastic parts used in automobile fuel sensor should have good temperature resistance, and the high temperature should be 150 degrees, and the low temperature should be MINUS 50 degrees, so the plastic hollow pepper ball (plastic nylon hollow pepper ball) used in fuel sensor can only meet this requirement.

PA plastic floating ball (PA nylon hollow pepper ball) has good oil resistance (diesel oil, gasoline, kerosene), even in oil over 100 degrees, it will not cause fuel leakage in the automobile fuel tank due to deformation, and its safety performance is the best. PA plastic hollow pepper ball is also better than plastic balls made of other materials in terms of corrosion resistance and toughness. The manufacturing method of PA plastic nylon hollow pepper ball cannot use blow molding process, but is made by special thermal welding technology, so the production efficiency is not high.
