It can be if it is proven that their illness was caused by that material and not simply by using percentages which can be and are flawed. One example was what happened to Dow Chemical because of flawed science pertaining to silicone. Those implants did not cause the maladies that were assigned to them so all those payouts were bogus. The same went for Alar in Washington. That chemical was used on apples and blamed for poisonings resulting in huge settlements and almost the ruination of a major state crop yet was proven to be innocuous. Not everybody that inhaled lead or asbestos got sick so many got payouts based upon association notfacts.
