Longchang Chemical April 30, 2022 Project Announcement

Quick answer: UV monomers and oligomers are usually chosen by viscosity, adhesion, flexibility, shrinkage, and cure speed as a package. The most reliable formulas come from balancing those properties rather than maximizing only one.

On the one hand, it plans to invest in the construction of 60,000 tons/year acrylic acid and 50,000 tons/year butyl acrylate projects, which will form an industrial chain linkage with the 500,000 tons PDH project already put into operation and increase the capacity of acrylic acid and esters; on the other hand, it will use the hydrogen by-product of PDH and other plants to invest in the construction of On the other hand, we will use the hydrogen produced by PDH and other plants to invest in a hydrogen upgrading project.

At the 15th meeting of the 3rd session of the Board of Directors of Longchang Chemical held on April 28, 2022, the proposal of investing in the construction of 60,000 tons/year acrylic acid and 50,000 tons/year butyl acrylate project was considered and approved, agreeing that the Company should invest in the construction of 60,000 tons/year acrylic acid and 50,000 tons/year butyl acrylate projects. The details are as follows

I. Overview of the proposed project

1. Name of the proposed project: 60,000 tons/year acrylic acid and 50,000 tons/year butyl acrylate project.

2、Project implementation body: The project is invested and constructed by Longchang chemical.

3、The background and necessity analysis of the project

Acrylic acid is an unsaturated carboxylic acid with a wide range of downstream applications. It is an important intermediate between petrochemical bulk products and downstream fine chemicals, of which about 50% is used in acrylic esters and the remaining 50% is used in SAP and other polyacrylic acid copolymers. Acrylic acid and its esters, by themselves or mixed with other monomers, will undergo polymerization to form homopolymers or copolymers. Common monomers that can be copolymerized with acrylic acid include amides, acrylonitrile, vinyl-containing, styrene, and butadiene. These polymers are used to produce a wide variety of plastics, coatings, adhesives, elastomers, floor polishes and paints.
The propylene produced by the company can be transported to the project through the pipeline to provide sufficient raw material supply for the production of acrylic acid, which can further reduce the production cost of the products and enhance the profitability of the company’s products, which is of great significance to the company in extending the industrial chain, optimizing and improving the added value of the products and improving the overall economic efficiency of the company.

4、Project investment estimate and source of funds
The project is expected to have a total investment of 456 million yuan, of which 355 million yuan will be invested in fixed assets and 17.2 million yuan will be paved working capital, all of which will be self-financed by the company.
5. Project construction period: The project is expected to last for 12 months (excluding project declaration).
II. Impact on the company

The Company proposes to invest in the construction of 60,000 tons/year acrylic acid and 50,000 tons/year butyl acrylate projects, which are environmentally friendly, energy-saving and highly efficient, in line with the development plan of the national industrial policy. The project can form an upstream and downstream linkage of the industrial chain with the 500,000 ton/year propane dehydrogenation project of the Company and increase the production capacity of acrylic acid and esters, which is conducive to the advantages of industrial integration, thus effectively controlling costs and maximizing product benefits.

In addition

The first phase of the 30,000-ton-per-year methyl methacrylate (MMA) monomer project with an annual production capacity of 3,000 tons and supporting public auxiliary works is completed and will be officially put into operation soon.
The project, which was located in Binhai Industrial Park of Weifang City in 2020, mainly uses methanol and methyl acetate to synthesize methyl methacrylate, realizing the transformation from coal chemical to organic matter. Because of the uncertainties in the designed line and realistic operation, timely adjustment and technical transformation are needed, as of now, the six units of trial production have been carried out to the third unit.

Methyl methacrylate (MMA) is an indispensable monomer for the production of materials such as aerospace glass and electronic information devices. The project adopts the R&D achievements of the Institute of Engineering of the Chinese Academy of Sciences for many years and has completely independent intellectual property rights.

The proposed investment for the first phase of the project is 480 million yuan, and the proposed investment for the second phase is 1.2 billion yuan. When the 30,000-ton MMA monomer project is fully completed, it will accelerate the development of the downstream PMMA, coating,

 

How buyers usually evaluate UV monomers and resin systems

Most successful UV formulations are built by choosing the backbone first and then tuning the reactive monomer package around the substrate, cure method, and end-use stress. That usually produces a more stable result than choosing materials by viscosity or price alone.

• Start from the final property target: hardness, flexibility, adhesion, and shrinkage rarely point to exactly the same raw-material package.
• Screen the reactive package as a whole: oligomer, monomer, and photoinitiator choices interact strongly in UV systems.
• Use viscosity as a tool, not the only decision rule: the easiest-processing material is not always the one that performs best after cure.
• Check the real substrate: plastic, metal, label film, gel systems, and coatings can reward very different polarity and cure-density balances.

Recommended product references

• CHLUMICRYL HPMA: Useful when more polarity and adhesion support are needed in the reactive package.
• CHLUMICRYL IBOA: A strong low-viscosity monomer reference when hardness and good flow both matter.
• CHLUMICRYL TMPTA: A standard reactive monomer benchmark when stronger crosslink density is required.
• CHLUMICRYL EO3-TMPTA: Helpful when viscosity and cure behavior need to be tuned around the base package.

FAQ for buyers and formulators

Can one UV monomer or resin solve every formulation problem?
Usually no. Commercially strong formulas depend on how several components work together to balance cure, adhesion, flow, and durability.

Why should monomers be screened together with oligomers?
Because monomers can change viscosity, cure rate, shrinkage, and substrate behavior enough to alter the final ranking of the same backbone resin.
