Is this flooring a synthetic rubber or from the tree itself? Is there off gassing associated with the product?

Our 8mm Strong Rubber Rolls - Designer Series rolls are made with SBR rubber which is synthetic rubber. We can't guarantee that these rolls are latex free, but they would have very little to no latex in most orders. The product does have some smell to it which can be mitigated by mopping the flooring with a mild soap and water solution and letting it air dry. You may have to repeat this step a few times to get your desired result.
