bonsoir
J'espère vous aider, mais j'ai trouvé ces définitions, mais en anglais

Polyester (POE) lubricants are particularly recommended
for most applications with HFCs. The basic product
can be “tailored” for optimum performance in specific equipment
or applications. POE lubricants are first choice with
R134a, R407C, R410A or R404A.
POE lubricants will absorb moisture from the air and should
be handled carefully.

Polyalkylene Glycol (PAG) lubricants are widely used
in mobile applications such as automobile air conditioning
with R134a. (PAGs have a strong affinity for water
and are particularly liable to pick up moisture from the
atmosphere, therefore care in handling is essential.) POE
lubricants also absorb atmospheric moisture, and should be
handled so as to minimise exposure to air
bon courage
