Bio meaning bio-based or soy based. In fact a very small percent of the foam is actually bio-based. I have sprayed multiple sets of the bio-based foam and had problems with voids. I have talked to other contractors who have had similar problems.

In a nut shell bio based utilizes a soy based polyol as apposed to a petroleum based polyol the A component is no different. The are mostly open cells , Omega claims to have a closed cell but I have not used it.

so..if the A side is the same,,and it amounts to 50% of the blend...and the A side is a petro chemical product derivative...bio?

how much of the B side is actual soy oil?

my suppliers open cell is a sucrose base polyol...along with polyester chain extenders
(polyester utilizes PET II recycled plastics in its formulation i am learning)...so does that mean i too am spraying a bio product? or am i spraying that "nasty toxic foam" as one of the competitors calls it?

is the msds sheets for formulations bio or non-bio foam all that different..?
or are we dealing with MARKETING TRIPE?

You will probobly get a different answer depending if you talk to a bio based supplier or a petro based supplier. You are right, 50% of the end product is A and I believe to be able to be labeled "bio based" only around 10% of the B side has to be bio. So in actuality not much of the end product is "bio."

Marketing tripe.

As stated, the percentage of soy in the resin is pretty minor. A few of the smaller suppliers attempt to accentuate that aspect to appear green. Maybe they are green with envy..

There is one manufacturer that we spoke to in Tucson (at the SPF show) who claimed that his product was largely soy. Maybe so, maybe not.

It's all about marketing.
