Some standard content:
Chemical Industry Standard of the People's Republic of China Polybutylene terephthalate (PBT) Nomenclature of thermoplastic materials HG 2361--92 This standard refers to the international standard ISO7792/1-85 "Plastics-Polyalkylene terephthalate-Part 1: Nomenclature". 1 Subject content and scope of application This standard specifies the nomenclature of polybutylene terephthalate (PBT) thermoplastic materials. This nomenclature is named according to the purpose or processing method, characteristic properties, additives, type and content of fillers, and product series number or other properties that need to be indicated of polybutylene terephthalate (PBT) thermoplastic materials. This standard is applicable to commonly used polybutylene terephthalate (PBT) with or without colorants, additives and fillers. 2 Naming method The naming method of polybutylene terephthalate (PBT) thermoplastic material consists of abbreviation code and model. 2.1 Abbreviation code The abbreviation code of polybutylene terephthalate is specified as "PBT" 2.2 Model The model of polybutylene terephthalate is composed of the following parts: 000-00m Purpose or processing method Characteristic performance Additive Filling type- Filling content Product series number or other performance 2.2.1 Purpose or processing method The purpose or processing method of polybutylene terephthalate (PBT) thermoplastic material is expressed in English letters, see Table 1. Approved by the Ministry of Chemical Industry of the People's Republic of China on October 7, 1992 404 Implementation on May 1, 1993 Disc processing HG 2361—92 Table 1 Application or processing method code Application or processing method Extruded pipes, profiles, sheets Extruded films General application Characteristic properties or additives Application or processing method Wire and cable coating Monofilament extrusion Powder coating or sintering Characteristic properties and additives of polybutylene terephthalate (PBT), expressed in English letters, are shown in Table 2. Table 2 Characteristic performance or additive code Processing stability Anti-adhesion Characteristic performance or additive Powder, dry blend Foamable Heat aging stabilitywww.bzxz.net 2.2.3 Filler type Characteristic performance or additive Light and weather aging stability Good fluidity Improved impact performance Mold release agent Lubricant High strength Anti-warping Antistatic agent The filler types of polybutylene terephthalate (PBT) thermoplastic materials are represented by English letters, see Table 3. Table 3 Filler type code Calcium carbonate Filler type Note: 1) This type of filler can be identified by chemical symbols or other agreed codes. 2) Metal fillers can be identified by the chemical symbol of the metal element. 2.2.4 Filler content Filler type Mineral\, metal? ) Organic synthetic material 1) Talc The filler content of polybutylene terephthalate (PBT) thermoplastic material is expressed by two Arabic numerals. The content code and range are shown in 4. HG 2361—92 Table 4 Filler content code and range Content range >7. 5~~12. 5 >12. 5 ~17. 5 >17. 5~~22. 5 >22. 5~27. 5 >27.5~32. 5 >32. 5~37. 5 >37. 5~42. 5 >42.5~47.5 %(m/m) Content range >47.552.5 >52. 5~57. 5 >57.5~62.5 >62. 5~~67. 5 >67. 5~72. 5 >72. 5~~77. 5 >77.5~82.5 >82, 5~ 87. 5 For mixed fillers of different types, the relevant codes can be combined in parentheses with a plus sign "+". For example, 25% (m/m) glass fiber and 10% (m/m) mineral filler can be identified with (G+M) (25+10). 2.2.5 Product serial number or other properties Product serial number or other properties shall be identified by the manufacturer with agreed symbols or codes and may be omitted when not required. 3 Naming examples 3.1 A certain polybutylene terephthalate (PBT) thermoplastic material, for injection molding (M), flame retardant (F), without colorant (natural color, N), with glass fiber as filler (G), filler content 33% (m/m) (35), is named: PBTMFN-G35. 3.2 A certain polybutylene terephthalate (PBT) thermoplastic material, for extrusion molding (F), anti-warping (W), with colorant (C), with talcum powder as filler (T), filler content 15% (m/m) (15), is named: PBTEWC-T15.
