GB/T 37194.1-2018 (English Version) PDF

Scope: 1.1 This part of GB/T 37194 specifies the nomenclature system based on the classification of thermoplastic polydecansulfide materials. 1.2 Different types of polytetrasulfide plastics are distinguished according to the values of the following specified characteristic properties and specific uses and/or processing methods. Important properties, additives, colorants, fillers and reinforcements are based on a classification system: a) "melt Bulk mass flow rate or melt viscosity; b) density; c) tensile modulus. 1.3 This part of GB/T 37194 applies to all PPS materials. It applies to powder, granular or pelletized, unmodified Or materials modified by colorants, additives, fillers and reinforcing materials, etc. 1.4 Materials with the same designation do not necessarily have the same performance. This section does not provide engineering data, performance data or specific use and/or by specifying the material Data on the processing conditions required by the processing method. When necessary, these additional properties can be determined according to the test methods specified in ISO 28078-2. 1.5 In order to describe the special use of a certain thermoplastic material or to ensure the reproducibility of processing, the character group can be used 5 Give additional requirements (see 3.1).
