Application Summary AI generated

This standard establishes a designation system and classification basis for polybutene (PB) moulding and extrusion materials. It is applied by manufacturers and users in the plastics industry to uniformly identify and specify PB materials based on their characteristic properties, such as melt mass-flow rate and tensile modulus, for use in piping, packaging, and other extrusion or injection-molded products. The standard ensures consistent material naming and specification in technical documentation, procurement, and quality control across different suppliers and applications.
