GB/T 46830, "Plastic Liquid Crystal Polymers (LCP) Molding and Extrusion Materials," is the fundamental standard for liquid crystal polymers, providing a framework for their application. Product standards provide support. GB/T 46830 is proposed to consist of two parts.

1.Naming System and Classification Basis. The aim is to establish a standard model for naming liquid crystal polymer materials. Naming methods and classification principles.

2.Sample Preparation and Performance Determination. The aim is to establish suitable sample preparation methods and properties for liquid crystal polymer materials. It can determine the items, methods, and conditions. This document describes the characteristics of liquid crystal polymer (LCP) molding and extrusion materials, using specified characteristic performance values and recommended applications and/or specifications. Processing methods, key properties, additives, colorants, fillers, and reinforcing materials, etc., are used to evaluate different types of liquid crystal polymer molding and extrusion materials. The distinction was made. Plastic liquid crystal polymer (LCP) molding and extrusion materials Part

1 Scope

GB/T 46830.1-2026 is the Chinese national standard covering how an LCP grade is designated - the polymer whose molecules line up as it flows, giving the dimensional stability, the thin-wall flow and the dielectric behaviour that connectors and 5G antenna substrates need. Part 1 of the series, first edition, in force from 1 December 2026, with Part 2 on specimen preparation. It was issued on 25 May 2026 and takes effect on 1 December 2026, as a first edition. The document is under the responsibility of the China Petroleum and Chemical Industry Federation. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

1.Scope This document defines a naming system for liquid crystal polymer (LCP) thermoplastic materials, which serves as the basis for classification. Different types of liquid crystal polymer (LCP) thermoplastic materials are recommended based on the following specified characteristic property values and composition information. A classification system based on uses and/or processing methods, important properties, additives, colorants, fillers, and reinforcing materials. distinguish.

a) Tensile strength;

b) Flexural modulus;

c) Notched impact strength of the cantilever beam;

d) Melting temperature;

e) Load deformation temperature. This document applies to liquid crystal polymer (LCP) materials used in injection molding and extrusion, including unmodified, modified, and recycled liquid crystal polymers. This document does not imply that materials with the same name necessarily have the same properties. This document does not provide information for describing the special uses of materials. (or) the engineering data, performance data, or processing condition data required for the processing method. If necessary, the test methods specified in GB/T 46830.2 shall be used. The method determines these additional properties. To illustrate the specific use of a particular thermoplastic material, additional requirements may be given in character group 5 (see 4.1).

4 Naming System

4.1 Overview The naming and classification system for liquid crystal polymers is based on the following standard model.
