PPA plastic pepper ball belongs to semi-aromatic high-temperature resistant PA nylon ball, and its thermal deformation temperature is as high as 300 degrees. The long-term use temperature of PPA plastic pepper ball is between 180 degrees and 220 degrees, and its water absorption is low or negligible, and it has high dimensional stability. PPA plastic pepper ball has good mechanical strength.PPA plastic pepper ball belongs to semi-aromatic high-temperature PA nylon ball, and its thermal deformation temperature is as high as 300 degrees. The long-term use temperature of PPA plastic pepper ball is between 180 degrees and 220 degrees, and its water absorption rate is low or negligible, and it has high dimensional stability. PPA plastic pepper ball has good mechanical strength, and its rigid strength can replace some metal material balls. PPA plastic shows excellent chemical resistance, resistance to engine oil, gasoline, chlorine water, etc.
