January 13, 2024, Lianhong (Shandong) Chemical Co., Ltd., a wholly-owned subsidiary of Lianhong New Materials Technology Co., Ltd.90000 tons/year vinyl acetate (VA) A test run of the device was successful, and qualified VA products were produced on January 14. The start-up of the device was a complete success. At present, the VA device has achieved continuous and stable operation. At present, the VA device has achieved continuous and stable operation.

Lianhong Chemical's 90000-ton/year VA plant adopts domestic mature advanced technology and uses Lianhong Xinke's own ethylene as raw material. VA products are mainly supplied to Lianhong Xinke's EVA plant for production and use. The construction of the VA plant will start in October 2022 and will be completed by October 31, 2023. The smooth commissioning of the plant has completed the industrial chain of Lianhong Xinke, which will help Lianhong Xinke realize the complete self-supply of VA raw materials for the existing EVA plant, and will fully guarantee the stable supply of VA raw materials for the 200000-ton/year EVA plant under construction, further reduce the production cost and bring positive impact on the company's operation.

As a VA downstream industry, here we also give a brief introduction to the company's EVA industry layout, from the public information, the company layout of a total of 350000 tons/year of EVA production capacity.

Lianhong Xinke EVA Industrial Layout

lianhong Xinke's 100000-ton/year EVA device will be put into operation in 2015. ExxonMobil's autoclave process can produce EVA products with VA content of 3%-35% and MI index of 0.2-450g/10min. It is the first EVA device in China that can produce VA content of more than 30%. The main product grades are UL00218, UL00628, UL15028, UL40028, UL04533, etc. EVA products are mainly used in photovoltaic, cable, foaming, hot melt adhesive, coating and other fields.

On March 27, 2022, the company completed the EVA device technology upgrade and expansion transformation, using ExxonMobil tube + kettle type combined technology, on the basis of the original device for tube method expansion, after the transformation, the new production capacity of 50000 tons/year.

In February 2023, Lianhong Xinke's 200000-ton/year EVA and 300000-ton/year PO units were started. It is reported that EVA adopts Lyondell Basell high-pressure tube process technology, which mainly produces photovoltaic film materials with high added value. After the implementation of the project, the company will have both the world's leading Lyondell Basell tube process and Exxon Mobil kettle process, which is conducive to improving the flexibility of production operation and promoting the development of new products.

The PO project adopts the world's leading co-oxidation CHPPO process technology, which has the advantages of high product yield, less by-products, low unit consumption and low carbon emissions compared to other PO production technologies.

After all the units are put into operation, the company's EVA capacity will reach 350000 tons/year.

Lianhong Xinke POE Industry Layout

in the field of new energy materials, the company is also accelerating projects in POE.

January 5, 2024 the "Lianhong Huisheng Thermoplastic Polyethylene Elastomer (POE) Project" was selected as the "List of Advanced Manufacturing Industries for Major Projects in Jiangsu Province in 2024".

21 September 2023, Lianhong Wison New Materials Project held a cooperation signing ceremony. The landing of the Lianhong Huisheng New Material (POE) project will break the foreign monopoly in the field of polyolefin elastomer production technology, and has important strategic significance for breaking through the "stuck neck" technology and realizing localization substitution. It is Taixing Economic Development Zone to extend the chain. An important supporting project for the chain and the strong chain, it has a positive role in promoting the upgrading of the olefin industry chain and enhancing the core competitiveness.

Lianhong Xinke issued an announcement on the evening of August 23, 2023, stating that in order to strengthen its competitive advantage in the field of new energy materials, the company and Wison (China) Investment Co., Ltd. jointly invested and established a joint venture company Lianhong Wison (Jiangsu) New Materials Co., Ltd., Planning and construction 300000 tons/year POE (polyolefin elastomer) project, the first phase of 100000 tons/year, the second phase of 200000 tons/year, the production of POE photovoltaic film materials, toughening materials and other series of high-end olefin material products. The total investment of the project is 5.2 billion yuan.

Lianhong New Branch it is a mixed-ownership listed company under Legend Holdings. It has been cultivating new materials for many years. In the field of high-end polyolefin materials, it has strong technology accumulation and market channel advantages, especially in new energy materials. It has taken the lead in developing EVA photovoltaic film materials in China., The product is in a leading position in the industry.

Wison CIC after years of technology accumulation, independently developed a full set of POE (polyolefin elastomer) process technology reach the international advanced level. Wison will transfer the full set of technology to the joint venture company.
