CNCEC East China Engineering Science & Technology Co., Ltd (ECEC) recently participated in 2024 CHINAPLAS International Rubber and Plastics Exhibition held in Shanghai as an exhibitor from April 23 to 26.
The exhibition featured over 4,400 rubber and plastics companies showcasing the latest industry technologies and trends across a sprawling 380,000 square meters. Donghua Tianye, on behalf of ECEC, showcased its industrial practices in the rubber and plastics sector, emphasizing its commitment to biodegradable plastics.

At CHINAPLAS, Donghua Tianye exhibited 15 products, including PBAT, PBT, PLA, and lactide for industrial purposes, along with various compound products. Notably, we presented fully biodegradable mulching films and dust-proof nets, demonstrating our applications in industrial, pharmaceutical, and packaging fields. The booth attracted over 180 visitors, including more than 100 foreign customers from countries like India, Italy, Turkey, Uzbekistan, Iran and Bulgaria, with 55 potential cooperation leads.


Donghua Tianye, invested by ECEC, focuses on researching key core technologies for fully biodegradable materials, ensuring product quality through innovative production processes. Our PBAT products have undergone certification tests and offer uniform molecular weight distribution and excellent mechanical properties. Moreover, our PBT products, available in various viscosity specifications, undergo strict quality control to enhance stability and processing performance.
Additionally, Donghua Tianye showcased end-product development and manufacturing, demonstrating the environmental benefits of replacing traditional plastics with fully biodegradable alternatives. Our mulching films, packaging materials, and dust-proof nets has been successfully applied in various regions, contributing to the reduction of microplastic pollution and promoting green construction practices.

With the increasing demand for fully biodegradable plastics due to domestic environmental regulations, Donghua Tianye aims to promote technology industrialization and establish a closed-loop supply chain for eco-friendly chemical products, aligning economic development with ecological protection.
