Solvent Free Plastisol Inks
Some manufactures are lowering the total volume or solvents in their ink formulations to nearly zero. The good news is that the solvents, and their negative affects, are reduced or eliminated. One possible drawback is that it takes more water to clean processes equipment and screens than solvent based inks. And that the increased water use and the wastes are now going down the drain – to be either treated – or worse, released untreated into the environment.
Phthalate Free Inks
Here again, companies have found replacements for dangerous phthalates by using other phthalates or entirely different, less toxic chemistries. These are preferred.
Heavy Metal Free Plastisol Inks
Some manufacturers are producing harmful heavy metal free – or reduced metal content inks. These too are preferred.
PVC / Phthalate Free “Plastisol” Inks
Attention and concern regarding PVC content has motivated some ink manufacturers to find a replacement for PVC for traditional “plastisol” printing applications. These inks are being developed primarily around acrylic chemistry. In most cases, this is preferred to anything containing PVC polymers.
