Plastics. Polybutene-1 (PB-1) moulding and extrusion materials - Designation system and basis for specifications Ingestion-build-266356 Unified screw threads (UN)1 Scope This document establishes a system of designation for polybutene 1 (PB 1) thermoplastic materials which can be used as the basis for specifications. For the sake of simplicity, the designation polybutene 1 and the abbreviation PB are used in this document. The types of polybutene plastics are differentiated from each other by a classification system based on appropriate levels of the designatory property melt volume flow rate and on
