The vegetable oil (called PPO too) should the fulfill the DIN 51605, the RK-standard or the Weihenstephaner standard. The only value that may deviate is the iodine number, what could be smaller, as e.g. with mustadoill, palmoil and jatrophaoil, because the iodine number only makes the rapeseel oil distinguishable other vegetable oils.

We dissuade from the use of soyoil because of its high iodine number, lead to cokings and a stronger polimerisation. More to it in the downloadarea. At the moment some additives should be developed, which should avoid this problem. As soon as existed you can refer an effective additive naturally over us.

They can refer cold pressed rapeseel oil according to DIN 51605 at our two locations in 48653 Coesfeld and 39264 bias. Further information in by  Klümper & CoKG.
