Pentaerythritol tetraoleate (PETO)

Short Description:

Polyol ester — Pentaerythritol tetraoleate, PETO
CAS No.: 19321-40-5
Type: RJ-1454
Molecular Formula: C(CH2OOCC17H33)4
Appearance: Light yellow transparent liquid
Chemical Properties: Pentaerythritol oleate is a light yellow transparent liquid, and it is made by the reaction of pentaerythritol and oleic acid through a special post-treatment process. It has excellent lubricating properties, high viscosity index, good flame resistance, and the biodegradation rate is over 90%. It is an ideal base oil for 68 # synthetic ester type flame-resistant hydraulic oil.

PETO has excellent lubricating properties, high viscosity index, good flame resistance, and a biodegradation rate of more than 90%. It can be used to prepare hydraulic oil, chainsaw oil and marine yacht engine oil that require environmental protection; as an oily agent in It is widely used in steel plate cold rolling fluid, steel pipe drawing oil, cutting oil, die-casting release agent and other metal working fluids.

PETO has good surface film-forming properties. It can be used in soft and hard PVC sheets, board profiles, pipes, transparent bottle materials and heat shrinkable films. It can also be used as an intermediate and textile oil for textile and leather auxiliaries.
