Plastic compounds are very versatile materials that have been widely used in automobiles, home appliances, and so on. Plastic compounds are composed of neat resin, functional filler, elastomer, and additives to show performance such as high strength, stiffness, impact resistance, electrical and thermal conductivity, etc. To develop the compounds, researchers have tried many combinations of raw materials and processing conditions. This procedure, however, required a long period and considerable money and reduced competitiveness. To strengthen the competitiveness and effectiveness of R&D for the compounds, we have researched the digital transformation technologies of plastic compounds. First, we standardized vocabulary, unit, classification system, and database schema. Second, data generation infrastructures (so-called, miniature data factory, MDF) and a data collection system to get a large dataset were equipped. Finally, we gathered the dataset of plastic compounds which consisted of data related to raw materials, composition, processing conditions, and properties of compounds; and applied machine learning technology to build the property prediction models of plastic compounds. In this presentation, we will introduce our activities related to the digital transformation of plastic compounds R&D that we have carried out for the last several years.
