Fluorocarbon elastomer balls, they provide excellent corrosion, aging and high temperature resistance. They are mainly used as sealings and are not flammable.
Application
Check valves, safety valves and special pumps (sealing elements), for high temperature and aggressive environment applications.
Corrosion Resistance
Viton balls are resistant into water, steam, oxygen, ozone, mineral/silicon/vegetable/animal oils and greases, diesel oil, hydraulic fluids, aliphatic, aromatic and chlorinated hydrocarbons, methanol fuel. They are not resisting against polar solvents, glycols, ammonia gases, amines and alkalis, hot steam, organic acids with low molecular weight.
