NIST Polymer Database

The NIST Polymer Database is a comprehensive online resource that provides detailed information about thousands of polymers (materials made of long, repeating molecular chains). It includes data on their physical and chemical properties, such as melting points, density, and strength. Researchers and engineers use it to find materials suited for specific applications, to compare properties, and to support product development. Maintained by the National Institute of Standards and Technology (NIST), the database helps ensure consistent and reliable information for scientific and industrial use.
