TORAY PLASTICS (CHINA) CO., LIMITED

Introduction

Toray Plastics (China) Co., Limited (Chinese: 东丽塑料（中国）有限公司) is a Hong Kong–based company associated with the plastics activities of Toray Industries, Inc., the Japanese chemical-materials group founded in 1926. The company operates within Toray’s broader resin and plastics network, which supplies engineering resins, modified compounds, molded components, films, and related technical services to industrial customers across Asia.

Toray’s plastics business originated in 1953 with polyamide resins developed for its synthetic-fiber operations. It subsequently expanded into ABS, polybutylene terephthalate (PBT), polyphenylene sulfide (PPS), liquid-crystal polymers (LCPs), polyolefin materials, and molded plastic products. In China, Toray’s manufacturing and technical network includes facilities in Suzhou, Shenzhen, Chengdu, and Zhongshan, covering resin modification, resin compounding, injection molding, and the production and assembly of plastic components.

The company occupies an intermediate position in the plastics value chain: it connects Toray’s polymer and materials technologies with Chinese and regional customers requiring material selection, formulation, processing support, component development, and production assistance. Its importance is therefore associated less with commodity polymer volume than with engineering plastics, application-specific compounds, and integrated technical support for demanding sectors such as automotive, electrical and electronic equipment, communications, industrial machinery, and consumer products.

History and Development

Toray Industries began its plastics activities in 1953, initially producing polyamide resin to support its synthetic-fiber business. This foundation allowed the group to develop expertise in polymer synthesis, compounding, processing, and application engineering.

Several milestones shaped the development of the business:

• 1953: Toray established its plastics business around polyamide resin.
• Subsequent expansion: The product portfolio broadened to include ABS, PBT, PPS, and LCP, extending Toray’s capabilities from general-purpose materials toward high-performance engineering polymers.
• International network development: Toray’s resin division established production sites and technical centers in multiple countries, eventually reaching 21 technical centers and production locations in 11 countries.
• Expansion in China: Toray created a network of Chinese operating companies serving distinct functions, including modified-resin production in Suzhou and Chengdu, resin-compound manufacturing in Shenzhen, and precision molded plastic products and assemblies in Zhongshan.

Toray Plastics (China) functions within this regional development rather than as an isolated plastics producer. Its role reflects the broader localization of Japanese and international materials companies in China, where customers increasingly require local supply, rapid application support, and compliance with regional production requirements.
