Dong Sung Chemical Expands 'Organic Peroxide' Production in Yeosu, Accelerates Shift to Fine Chemicals

Investing 18 Billion Won to Add 4,000 Tons of Annual Production
"Key Material for Polymers... Global Demand on the Rise"
"Strengthening Position as an Eco-Friendly, High-Value-Added Business"

Dong Sung Chemical is accelerating its structural transformation by completing and commencing operations of a new organic peroxide facility at its Yeosu plant. The company has been pursuing a shift toward fine chemicals, reducing its traditional petrochemical segment.

Dong Sung Chemical has signaled the expansion of its fine chemicals business. On September 30, the company announced that it had completed the expansion of its organic peroxide production line at the Yeosu plant in Jeollanam-do and had begun full-scale operations. With this expansion, Dong Sung Chemical has secured an additional annual production capacity of over 4,000 tons.

The company is restructuring its business with a focus on reducing its petrochemical operations and strengthening its high-value-added fine chemicals segment. Since 2023, Dong Sung Chemical has dismantled more than 70% of its petrochemical facilities at the Yeosu plant and invested approximately 18 billion won in the recent expansion, all in line with this strategy.

Organic peroxide is a key material used as an "initiator" to start the polymerization of polymers such as low-density polyethylene (LDPE), polyvinyl chloride (PVC), and ethylene vinyl acetate (EVA), and as a "crosslinking agent" that strengthens polymer chains. Dong Sung Chemical analyzed that global demand for organic peroxide is increasing every year, as it is utilized across high-value-added industries including solar panels, automotive parts, and wire coatings.

In particular, the company is working to localize powder-type products, aiming to internalize items that have traditionally been highly dependent on imports. CEO Lee Manwoo stated, "We will respond to growing global demand while also contributing to the stable supply chain of domestic industries. We will foster fine chemicals as an eco-friendly, high-value-added business and solidify our presence in the global market."
