Morflex
Inc.'s Citroflex®
citric acid esters afford a wide range of benefits
when used as plasticizers in aqueous- and solvent-based polymers,
including acrylic, methacrylic, ethylcellulose, hydroxymethyl
cellulose, nitro cellulose, vinyl acetate, vinyl chloride,
vinylpyrrolidone vinylidene chloride and urethane polymer formulations. Citroflex®
esters offer formulators a unique combination of environmentally
friendly features. They are neither "Volatile Organic Compounds" (VOCs)
nor "Hazardous Air Pollutants" (HAPs) and
they combine powerful solvency with low toxicity, high flash points and
rapid biodegradability. The Citroflex esters have wide applicability in industrial,
pharmaceutical, cosmetic, coating, ink, medical and food related products. Information relating
