The Shanghai Petrochemical 200,000-ton/year second-generation polypropylene polypropylene loop technology development project has been successfully implemented. This technology has innovations in the catalyst, polymerization process, hydrogen separation system design and prepolymerization process with independent intellectual property rights, and forms a proprietary technology.
The project was jointly developed by three units including Shanghai Petrochemical, China Petrochemical Engineering Construction Corporation and Beijing Chemical Research Institute. As a device construction unit, Shanghai Petrochemical Co., Ltd. took charge of the related work such as construction and operation, and inspection and acceptance, and also undertook the preparation of process technical regulations and operating procedures, industrial application tests of DQ catalysts, and completed two new high-modulus modulus Pilot scale up and industrial trial production. Sinopec Engineering Construction Co., Ltd. undertook the basic and detailed design. The Beijing Chemical Industry Research Institute mainly undertakes the production amplification and industrial application of DQ catalysts, and develops 8 new product brands including the new generation of bimodal, high-impact and high-modulus work.

Pulp tray is a packaging material that usually made from recycled paperboard or newsprint. It is a protective packaging for electronic products, food, beverage carriers. In many cases, pulp tray is considered as a less expensive packaging material compared with PET, PVC, EPE, EVA and so on. It is made from recycled materials, and can be recycled again after used. Normally, it is produced by two ways: dry press and wet press. Dry press is cheaper and faster. Wet press is more expensive and take a longer times to produce.
