Good news! POE pilot plant put into production again! Follow-up planning capacity of 500,000 tons / year

On September 28, Dongfang Shenghong issued an announcement that the 800 tons/year POE (polyolefin elastomer) pilot plant invested and built by Jiangsu Sierbang Petrochemical Co.
, Ltd.
, a wholly-owned subsidiary of the company, successfully realized the complete autonomy of POE catalyst and a full set of production technology, and the project was successfully started at one time, smoothly opened the whole process, produced qualified products, and continuously and stably operated
.

It is reported that the successful start-up of the device marks that Sierbang has become the only enterprise
in China that has two mainstream photovoltaic film materials independent production technologies of photovoltaic grade EVA (ethylene-vinyl acetate copolymer) and POE (polyolefin elastomer).

In addition, according to the strategic layout of Dongfang Shenghong New Energy and New Materials, in the future, Sierbang will continue to focus on the research and development and capacity expansion of photovoltaic-grade EVA and POE, of which the EVA master plan has an annual production capacity of 1 million tons (currently has a production capacity of 300,000 tons), and the POE master plan has an annual production capacity of 500,000 tons (phased construction), creating a leading enterprise
in the supply of photovoltaic film raw materials.

On April 19, Jiangsu Sierbang Petrochemical Co.
, Ltd.
published an environmental impact report of 800 tons / year POE pilot plant on its official website, according to the information on the EIA document, the project uses ethylene as raw material, under the action of a catalyst of a highly active single active center, with hexane as the solvent, octene as a comonomer, polymerization to produce POE products, the main chemical reactions are as follows:

According to the introduction, the POE process package adopts the patent of the Canadian Wallkan company, and the process adopts solution polymerization, and the process passes through no circulation
at one time.
The pilot project has the following aspects of construction:

Catalyst verification: the domestic self-developed catalyst in cooperation with scientific research institutes is produced, and the catalyst is evaluated in combination with the reaction conversion rate of the main section of the device, and the scope of the comonomer of the catalyst (production density, melt index) is clarified;

Product performance analysis: under the conditions of the above catalysts, through the downstream enterprises to verify the production density of 0.
860-0.
930, melt index 0.
6-50 in the range of a variety of products, analysis and determination of small class brands, the formulation of corresponding enterprise standards, to promote the formulation of
industry standards.

Based on catalyst verification and product performance analysis, we will effectively improve the process flow and parameters to provide experimental data
for industrial devices.

In addition, after the expiration of the operation period of the pilot plant, it will be transformed in accordance with the requirements of the "Jiangsu Provincial Pilot Base and Pilot Project Management Measures (Trial)" (Su Gong Xin Gui [2021] No.
2), build a new pilot project, continue to provide new product production control parameters for the industrial device, and help
the development of Sierbang.
