What is carbon black? A vital component in making many of the products we use every day stronger, deeper in color and longer lasting, carbon black in its pure form is a fine black powder, essentially composed of elemental carbon. It is produced by partial burning and pyrolysis of low-value oil residues at high temperatures under controlled process conditions.
Lower-molecular-weight phthalates, those derived from C3-C6 alcohols, are being gradually replaced in many products in the United States, Canada, and European Union over health concerns. They are replaced by high-molecular-weight phthalates (those with more than 6 carbons in their backbone, which gives them increased permanency and durability). In 2010, the market was still dominated by high-phthalate plasticizers; however, due to legal provisions and growing environmental awareness and perceptions, producers are increasingly forced to use non-phthalate plasticizers.
