T/CPPIA 27-2023 The color masterbatch used for the mixed composition of random copolymer polypropylene (PP-R) is referred to as "PP-R mixed color masterbatch"

Scope

Scope: This document specifies the terms and definitions, color category codes and product codes, materials, requirements, test methods, inspection rules, marking, packaging, transportation, and storage for color masterbatches used in the preparation of compounding materials for polypropylene random copolymer (PP-R) piping systems for cold and hot water applications. This document applies to color masterbatches prepared using polypropylene random copolymer (PP-R) as the carrier resin for the production of compounding materials for polypropylene random copolymer (PP-R) piping systems for cold and hot water applications. Main technical contents: 6.1 Colors are generally white, gray, or green. Other colors can be determined by mutual consultation between the supplier and the buyer. 6.2 Appearance: Color masterbatches should be uniform in size, with a smooth surface, consistent color, and no impurities or discolored particles. 6.3 Performance of color masterbatches: Color masterbatches should meet the requirements specified in Table 2. 6.4 Hygiene requirements: They should comply with the requirements of GB/T 17219. 6.5 Suitability of compounding materials: 6.5.1 Compounding materials prepared using color masterbatches and polypropylene random copolymer (PP-R) resin according to the nominal addition amount should be graded in accordance with the requirements of GB/T 18252 and comply with the requirements of GB/T 18742.1. 6.5.2 The performance of injection-molded samples prepared by mixing color masterbatches and polypropylene random copolymer (PP-R) resin according to the nominal addition amount should meet the requirements specified in Table 3.
