This book was released on 2023-05-02 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document specifies the methods and conditions for the specimen preparation and properties determination of polypropylene (PP) molding and extrusion materials. This document also specifies the requirements for the pre-treatment of test materials and the conditioning of specimens before testing. This document lists properties and test methods suitable and necessary for characterizing polypropylene (PP) molding and extrusion materials. These properties are selected from the general test methods of GB/T 19467.1. This document also lists other test methods extensively applied or of special significance for molding and extrusion materials, as well as the determination methods of the properties designation in Part 1. In order to ensure that the test results are reproducible and repeatable, it is necessary to use the methods of specimen preparation and conditioning specified in this document, as well as the specified specimen sizes and test methods. The test data obtained using specimens prepared under different conditions or using specimens of different sizes may not be consistent.

This book was released on 2023-05-02 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document specifies the designation system of polypropylene (PP) thermoplastic materials, and this system can be used as the basis for specifications. Different types of polypropylene thermoplastic materials are distinguished by a classification system based on the following specified characteristic property values and recommended purposes and (or) processing methods, important properties, additives, colorants, fillers and reinforcing materials, etc.: a) tensile elastic modulus; b) Charpy notched impact strength; c) melt mass-flow rate (MFR). This document is applicable to all propylene homopolymers and other propylene copolymers with a mass fraction of 1-olefin monomers less than 50% and blends of the above-mentioned polymers with a mass fraction of not less than 50%. This document is applicable to materials that are conventionally in the form of powders, granules or crumbs, unmodified or modified by colorants, additives and fillers, etc. This document does not apply to propylene-based rubber. This document does not imply that materials with the same designation will necessarily have identical properties. This document does not provide the engineering data, property data or processing condition data necessary to describe a particular purpose and (or) processing method for the materials. If necessary, these additional properties can be determined in accordance with the test methods specified in GB/T 2546.2. In order to illustrate a particular purpose of a certain polypropylene thermoplastic material or to ensure the reproducibility of processing, additional requirements may be provided in data block 5.
