Nitrile Glove:
Slip & puncture resistant and minimum chemical resistance


Neoprene Gloves
They protect against hydraulic fluids, gasoline, alcohols, organic acids and alkalis. They generally have chemical and wear resistance properties superior to those made of natural rubber.


Butyl Rubber gloves:
Best against Acetone, MEK, MIBK and Esters


Viton over Butyl unlined glove.
Applications: aliphatic hydrocarbons aromatic solvents, chlorinated solvents cleaning equipment, corrosives etc
