Methyl Palmitate / Oleate

CAS Numbar-67762-38-3

The UNICON SP 5 (Heavy Cut Methyl Ester) is a mixture of Methyl Palmitate (C16, 15- 30%) and Methyl Oleate (70-85%); “R” in the structural diagram above represents a  saturated alkyl chain of carbon atoms equal to 15 or 17. Not including the methyl ester  group, there are an even number of carbon atoms in the molecule. It is a clear Liquid  under ambient conditions with a musty odor.

∙ Methyl Esters attack, swell and soften many different types of rubbers and plastics  such as gaskets and hoses. 

∙ Concrete is slowly swollen & deteriorated by contact; avoid recurring drips or leaks,  and clean up spills promptly. 

∙ Ambient temperature is acceptable even if it is higher than the maximum  temperature.
