The successful operation of the POE pilot plant of Sierbang Petrochemical will fill the gap in China's industrial production

On September 26th, in Jiangsu Lianyungang Petrochemical Industry Base, Shenghong Sierbang Petrochemical 800 tons / year POE (polyolefin elastomer) pilot plant produced qualified products, and the project was successfully
started at one time.
This marks that Sierbang has become the only enterprise in China that has both photovoltaic grade EVA (ethylene-vinyl acetate copolymer) and POE (polyolefin elastomer) two mainstream photovoltaic membrane materials independent production technology, which will provide a solid material guarantee
for the high-quality development of China's new energy industry.

The "dual carbon" target has driven a rapid increase in POE demand

POE (polyolefin elastomer) is a kind of ethylene / α - olefin two monomers of random copolymer, has good low temperature toughness, easy to thermoplastic processing, widely used in photovoltaic adhesive film, polyolefin material toughening and modification, foaming, adhesive and other fields
.
In recent years, the rapid growth of emerging industries such as automobile lightweighting, plastic instead of steel, photovoltaics, and artificial grass have all driven the explosive growth
of POE demand.

Especially driven by
the photovoltaic industry.
Under the background of the current "carbon neutrality", the rapid development of the photovoltaic industry has significantly driven the development of photovoltaic adhesive films, the demand for POE has increased significantly, and the product market prospects are better
.
According to statistics, in 2021, China's POE consumption will be about 640,000 tons, of which the demand in the photovoltaic field accounts for 40%, and the automobile market accounts for 26%.

According to the data of China Photovoltaic Industry Association, as of 2021, China's photovoltaic module production has reached 182GW, and the current market penetration rate of POE photovoltaic film has been between 27% and 30%, and by 2021, the domestic photovoltaic film POE demand is 250,000-300,000 tons
.
POE has the advantages of low volume resistivity, low water vapor transmittance, good aging resistance, and low potential induced attenuation in the photovoltaic field, and the permeability will be further improved
in the field of photovoltaic film.

According to the growth rate expectation of ASIACHEM Consulting for the annual growth rate of photovoltaic module production to 325GW in 2022-2025, it is estimated
that the penetration rate of POE photovoltaic film will increase to 35% and 45% year by year.
Under conservative circumstances, the domestic POE film demand will increase from about 260,000 tons in 2021 to about 570,000 tons in 2025, and in an optimistic situation, the demand for POE film will reach about
730,000 tons.
This means that the POE demand in the photovoltaic field in 2025 is 2.
2-2.
8 times that
of 2021.

Independent research and development to break the monopoly will fill the gap in POE industrialization

According to relevant statistics, the global POE production capacity in 2021 is about 1.
58 million tons
.
Due to the patent protection of foreign enterprises for the catalyst required for the production of POE, and the process technology of high-carbon α-olefins, an important raw material for the production of POE, the current global POE production capacity is mainly concentrated in foreign companies such as Dow Chemical, Mitsui Chemical and ExxonMobil, and no domestic enterprises can industrialize the production of POE products
.

As a national high-tech enterprise and a leading R&D enterprise of new energy and new materials in China, Sierbang Petrochemical launched independent research and development
of POE key technologies in September 2020.
After more than a year of scientific and technological research, the R & D team has completed the research of metallocene catalyst and key polymerization technology, and developed the pilot process technology, and built a pilot plant
from catalyst preparation to extrusion granulation.
At present, the device is the most complete process, the most comprehensive facilities, and the closest to the industrial reality of the pilot plant
.

Bai Wei, president of Shenghong Petrochemical Industry Group and general manager of Sierbang Petrochemical, said that the 800 tons / year POE pilot plant was completed and put into operation, realizing the complete autonomy of POE catalyst and a full set of production technology, which can provide technical support and experience accumulation for industrial production equipment, and accelerate the industrialization process of China's POE, fill the gap in the industry, but also mark the further improvement of the company's research and development capabilities and high-end products, and will continue to lead China's new energy materials industry
.

Double line parallel to create the world's largest photovoltaic membrane material base

New chemical materials are the key materials required for national economic construction, and are also typical representatives
of the national industrial and industrial development level and the overall technical level.
New chemical materials have always been a short board in the development of China's petrochemical industry, and key technologies are subject to people, resulting in the structural contradiction of "excess of low-end products and shortage of high-end products" in China's petrochemical industry for many years
.
Data show that in 2021, China's chemical new material output of about 29 million tons, but the consumption is as high as about 40.
5 million tons, the gap is nearly 11.
5 million tons, and the self-sufficiency rate of new chemical materials is only about 71%, which restricts the development of
downstream high-end manufacturing industry.

This situation is also reflected
in the field of new energy.
Taking the current mainstream photovoltaic film material EVA as an example, the import dependence exceeds 60%, which has caused greater cost pressure
on downstream photovoltaic module companies.
After the national "double carbon" goal was proposed, photovoltaic new energy is generally regarded as a key industry for carbon emission reduction, Sierbang Petrochemical aims at the core raw material supply shortcomings of the photovoltaic industry, increases investment, builds a platform, carries out innovative research and development for the national strategy and market demand, and successfully masters a series of core independent technologies such as the production process of EVA photovoltaic membrane materials, providing strong support
for the national green energy transformation.

As the largest manufacturer of EVA photovoltaic membrane materials in China, Sierbang currently has a photovoltaic grade EVA production capacity of 300,000 tons / year, the company is actively promoting the construction of 700,000 tons / year EVA project, after the full completion of the EVA total production capacity will reach one million tons, the global market share will exceed 40%.

According to Bai Wei, Sierbang Petrochemical is planning to build a 500,000 tons/year POE photovoltaic membrane material project to create a horizontal coverage and chain extension of the whole industrial chain of photovoltaic new materials to meet the strong demand
for photovoltaic membrane materials in the development of China's new energy industry.
POE and EVA go hand in hand, and Sierbang Petrochemical is accelerating towards the goal of "building the world's largest photovoltaic membrane material industry base"
