GB/T 21460.1-2008

This standard establishes a designation system for styrene-acrylonitrile (SAN) moulding and extrusion materials, providing a structured method to identify and specify these plastics based on their composition and key properties. It is applied by manufacturers and suppliers in the rubber and plastic industry to classify SAN materials for use in injection moulding and extrusion processes, such as producing household appliances, automotive components, and packaging items. The standard also serves as the basis for creating technical specifications in procurement and quality control, ensuring consistent material selection and performance evaluation across different production contexts.
