The fuel sensor in the fuel tank of the aircraft will use plastic nylon hollow pepper balls to seal the fuel tank. The quality of plastic hollow pepper balls will greatly affect the safety performance of the aircraft. PA nylon hollow pepper balls used in the aircraft must be resistant to kerosene and low temperature.

There are few kerosene-resistant plastics. At present, the best kerosene-resistant plastic is nylon plastic pepper ball. The plastic hollow pepper ball made of nylon plastic can well meet the quality requirements of air compressor sensors for nylon hollow ball. Another advantage of PA plastic hollow pepper ball is its good toughness, no breakage, high strength and high precision, and its diameter precision can reach within 0.02 mm. The PA plastic nylon hollow pepper ball developed by our company is not only applied in automobile industry, but also in military air compressors.
