Making castor oil based polyurethane

13 Posts

Hello,

My name is Budi Santoso, I am undergraduate student at university of Indonesia. Right now I am doing my final project of preliminary designing a plant that uses castor oil as the raw material.
I am planning to produce castor oil based polyurethane resin.

Sir/Madam, can I ask for your help. Until now I have not found the process and material explaination of making castor oil based
polyurethane. Could you explain me the process and material for making
castor oil based polyurethane resin (a process flow diagram would be very helpful).
Also, do you know if there is an existing castor oil based
polyurethane resin plant?

Thank you Sir/Madam for your attention and help, I am looking
forward to receiveing your reply.


Sincerely yours,

Budi Santoso

making PU from castor oil its very easy. you directly react isocyanate with castor oil in stoichometric ratio. However, which type of PU you want to make exactly.
thanks and regards

Dear Suresh & Budi
Castor Oil when used as the polyol yeilds polyurethanes with limited hardness and mechanical properties compared to the refined natural oil based products.
Natural oils and fats, especially their hydroxy functional derivatives can be used as the starting materials in the manufacture of polyurethanes. The refinement of natural oils to polyols for the polyurethne industry can take place in different ways. Basic technologies like esterification, transesterification, epoxydation, ring-opening reaction, ethoxylation or propoxylation results in the production of versatile polyols for the polyurethane industry.
This chemistry is not all that simple. I wish it was.
Budi, trust this explanation is somewhat understood. Best of luck to your project.
Best wishes to all,

Try a BASF product which may or may not be available now, called Lupranate (I can't remember which series number). This is a reasonably fast acting poly-isocyanate. Alternatively, you might try to procure a range of active polyisocyanates and test which provides you with the mechanical properties you desire. Inclusion of mineral fillers will allow material to act as a polymer-based concrete when properly formulated. You will still have to do your home (lab) work! Best regards. AVPeters

Dear budi
making castor oil based polyurethane is possible. all u got to know is the proper initiator to react with castor in the transesterification reaction. this gives u basic polyol. there after depending upon what pu u want to produce, u can do so.

Dear Budi,
Also I am a Master of Science student in Turkey and working in a trader co. who imports and exports some specialty chemicals. I have the same question with you. Could you pls send us process, if you get it.
Kind Regards,
Tuna CALIS

Hi Budi, I am one of the pioneer in the production of polyol from vegetable oils this including palm oil, rapeseed oil, canola oil, soyabean oil, coconut oil and fish oil. I start my research since 1997 till now.

Dear Budi Santoso,
What did you with "castor oil based resin". What is the situation with you now?

Hai,

My name is Nagesh ,residing in Hosur a Town in Tamil Nadu State,India.We are using Polyurethane resin which is used for potting of Capacitors ,which we are manufacturing.During the preparation of resin we facing lot of air bubbles in the resin.We suspect this on the filler which we are using namely Silica powder.kindly suggest a better filler so that the resin appears smooth and without air bubbles.

The castor seed contains ricin, a toxic protein. Heating during the oil extraction process denatures and inactivates the protein. However, harvesting castor beans may not be without risk.[8] Allergenic compounds found on the plant surface can cause permanent nerve damage, making the harvest of castor beans a human health risk. India, Brazil, and China are the major crop producers, and the workers suffer harmful side effects from working with these plants.[9] These health issues, in addition to concerns about the toxic byproduct (ricin) from castor oil production, have encouraged the quest for alternative sources for hydroxy fatty acids.[10][11] Alternatively, some researchers are trying to genetically modify the castor plant to prevent the synthesis of ricin.
