Bishop´s
PD-571 is a unique pour point depressant designed to lower
the pour point of vegetable oils. It also lowers the cold
filter plugging point (C.F.P.P.)
Application:
Bishop´s PD-571 is an effective pour point depressant for
most vegetable oils. Recommended treat rate is 1-2%. The
following table shows the effect of 1% Bishop´s PD-571 on
the pour point of some vegetable base oils:
Base stock High Oleic High Oleic Canola Oil, Sunflower Oil
Canola Oil
Pour Point (oC)
0%PD - 571 - 12 - 21 -18
1%PD - 571 - 24 - 30 -36
Bishop´s PD-571 is also useful in reducing the pour point
and cold filter plugging point of methyl esters of vegetable
oils (such as rapeseed and soybean oils)
The addition of various levels of Bishop´s Pd-571 to
rapeseed methyl esters (RMEs) will provide the following
results in pour point and cold filter plugging point (C.F.P.P.)
0.00 - 12 - 5
0.25 - 36 -14
0.50 - 39 -16
1.00 - 42 -23
Final :
The
maximum value of depression curve doesn´t reach over the
value of -22.5oC ever with higher quantity of Pour Point
Depressant PD-571. It´s a great success and a proof,
that this additive Really works with Methyl Esters and
belongs to depressants with highest force.
