Dagou Chemical Empowers Standards: Deeply Involved in the Development of the National Standard for Transparent ABS
On March 26, Tianjin Dagou Chemical Co., Ltd. announced that it recently participated in the development of two national standards for transparent ABS: GB/T 46827.1-2025, “Plastics—Methyl Methacrylate–Acrylonitrile–Butadiene–Styrene (MABS) Molding and Extrusion Materials—Part 1: Nomenclature System and Classification Basis,” and GB/T 46827.2-2025, “Plastics—Methyl Methacrylate–Acrylonitrile–Butadiene–Styrene (MABS) Molding and Extrusion Materials—Part 2: Preparation of Test Specimens and Determination of Properties.” These standards have been officially released and will be fully implemented starting July 2026.
Tianjin Dagou Chemical Co., Ltd., leveraging its end-to-end production expertise and deep technical foundation in the transparent ABS sector, played a pivotal role in revising this standard. Drawing on its well-established standard procedures, the company provided critical support for key aspects of the national standard, including product quality, inspection, and performance testing.
Under the authoritative guidance of the Petrochemical Plastics Resin Products Sub‑Committee of the National Technical Committee for Plastic Standardization, the company not only supplied high‑quality reference materials and standard test specimens during the revision process and conducted comprehensive quality inspections, but also integrated its long‑standing, standardized procedures in the transparent ABS field into every stage of national standard development. From product nomenclature and classification to sample preparation and performance testing, numerous critical steps drew heavily on Tianjin Dagou Chemical’s production practices and quality‑control system, ensuring the accuracy and reliability of test data as well as the scientific rigor of the standard text. During the technical review phase, the company further leveraged its expert perspective to put forward a series of practical amendment proposals, laying a solid foundation for the ongoing refinement of the standard.
Standards serve as the guiding beacon for industry development and, more importantly, as a tangible manifestation of a company’s core competitiveness. The recent release of two national standards has filled critical gaps in the field of transparent ABS materials, covering nomenclature systems, classification frameworks, and performance‑testing methodologies. As the first domestic manufacturer to successfully produce transparent ABS (MABS) resin via an emulsion‑grafting bulk SAN blending process, Tianjin Daguhua has played a pivotal role in drafting these national standards, thereby underscoring its leading position in the transparent ABS sector and earning authoritative recognition.
This in-depth participation in the development of the national standard not only serves as strong validation of the company’s R&D capabilities and its level of standardization efforts, but also represents a key step in advancing the company’s “Three Ones” strategy. By gaining a voice in shaping industry standards, the company has further strengthened its quality leadership and brand influence in the transparent ABS sector, laying a solid foundation and building momentum for its 2026 goal of becoming the domestic leader in transparent ABS.
