Frequently asked questions
Up to 83% bio carbon content.
A rough calculation of GHG in our products suggests that our CO2 footprint is 260-300 kg/t. A full LCA is coming soon.
In comparison 1t of fossil based polyol, releases up to 4100kg/t of CO2 into the atmosphere.
By composition, they are similar to polyester polyols. However, in formulations, our Bio polyols behave more like polyether polyols. If possible, we suggest replacing petrochemical polyether polyols with our Bio polyols.
We use natural oils, e.g. industrial grade rapeseed oil and second generation feedstock – pine based chemicals which are reducing the CO2 footprint even more.
Our Bio polyol OH values vary from 260 to 410. The products are based on Alkanolamines (so primary OH-groups, which are not too far away from each other, including an amine-reactive centre = autocatalytic) and a long hydrophobic side chain, which could make the foam more hydrophobic.
These bio polyols currently are used for rigid PU products like spray foam, steel sandwich panels, block foam, etc
Our production capacity is approx 10 000 t p.a.
Our bio polyols are amber yellow, light brown, and dark brown colored. They do not have strong smells. Depending on the amount added they can have a minor effect on the end foam color.
Our bio polyols are at the same price ranges as fossil-based polyols and significantly lower than other bio-based polyols.
Our bio polyols have a functionality of 2 and you will need a cross-linking polyol with a functionality of at least 5.
Due to high OH values or Bio polyols are mostly used for rigid foam applications. They have shown good results in OCF and fast curing adhesives.
Our products are in full compliance with REACH regulation.
