Raw material source: Soybean oil - based polyols are derived from renewable plant oils (soybean oil), while petroleum - based polyols rely on non - renewable petroleum resources.

Environmental attributes: During the production and use of soybean oil - based polyols, carbon emissions are lower, and some products have a certain degree of biodegradability, which is more in line with the concept of "green chemistry".

Molecular structure: Soybean oil - based polyols retain the long - chain fatty acid structure of vegetable oils. In addition to hydroxyl groups, the molecules also contain groups such as ester groups and double bonds, making their properties more adjustable.
