Advantage
● These saddles are made from chemical porcelain and have excellent resistance to acids except in the case of hydrofluoric acid.
● Moisture absorption must less than half a percent.
●The porcelain’s specific gravity is 2.3-2.4g/cm3 and an average heat capacity (between 20℃ and 500℃ of 0.22 cal/g.℃)
XINGFENG ceramic saddles softening point is 1400℃ min. And they show good thermal shock resistance during repeated cycling between 20℃ and 820 ℃.
