T/CRRA 0312-2026 Applied specification for recycled plastics in vehicles——Part 2: Polypropylene

Scope

This document specifies the basic requirements, labeling requirements, content calculation methods, classification, application scope, and performance requirements for automotive recycled polypropylene (PP) materials, and describes the corresponding test methods. This document applies to recycled polypropylene used in the manufacture of automotive parts, which is made from waste plastics that are non-hazardous and non-radioactive, and processed through physical or chemical methods such as sorting, modification, and granulation. The standard includes the following five chapters of technical content: Chapters IV to VI, in accordance with the "Specification for the Use of Recycled Plastics in Automobiles - Part 1: General Principles", provide the basic requirements, labeling requirements, and content calculation methods for the application of recycled polypropylene in automobiles. Chapter VII, Classification and Application Scope: This section classifies automotive recycled polypropylene into non-filled and filled types, clarifies the definitions of each type of material, and recommends application scenarios and suitable proportions. Enterprises are allowed to make reasonable adjustments provided that they meet performance and safety requirements. Chapter VIII, Performance Requirements: This section provides key performance indicators for various types of recycled polypropylene, including density, load deformation temperature, tensile strength, bending performance, impact strength, aging resistance, scratch resistance, and combustion performance. It also specifies the corresponding test methods to ensure that the material performance meets automotive requirements.
