We offer a comprehensive range of polymer science products, including monomers, polymers, polymer additives, and polymerization initiators. Polymers are grouped in sections by chemical functionality: hydrophilic, hydrophobic, block-copolymers, silicones, and poly(ethylene glycol)/poly(ethylene oxide). The engineering polymers section includes products, such as thermoset epoxies and plastics, which are commonly used in technological applications. Cellulose, chitin and other polymers of natural origin are grouped in the natural polymers section. The biodegradable polymers section includes materials that readily degrade to biologically benign components and are often used in biomaterials research. Products used to synthesize polymers and formulate polymeric materials are grouped by chemical functionality and application in the monomers, additives, and initiators sections.
