Made of fluorinated elastomer, these balls are distinguished by their exceptional resistance to corrosive agents, ageing and high temperatures. They are particularly suitable for use as sealing elements under severe conditions. Marteau- Lemarie, a trusted supplier with 40 years of expertise, has these products in stock in France for quick delivery.

Corrosion resistance of the viton rubber ball
They are perfectly resistant in water, steam, oxygen, ozone, mineral oils and fats, silicones, plants and animals, diesel, hydraulic fluids, aliphatic, aromatic and chloride hydrocarbons, methanol-containing fuels. They are not resistant to polar solvents, glycols, ammonia gases, amines and alkalis, overheated water vapour, low molecular weight organic acids.
Applications of Villon Rubber Ball
Non-return valves, safety valves, special pumps (seam elements), always in high temperature applications and in aggressive environments.
Rubber mixtures from 55 Shore A can be supplied.
