Changhong Carbon Black Seminar: 26 Masterbatch Enterprises Gather in Dongguan, Production Capacity to Expand to 420,000 Tons

On the afternoon of October 22, a seminar and appreciation meeting on masterbatch raw materials and Changhong carbon black, hosted by Ningbo Dongyi Rubber and Plastic Products Co., Ltd. and organized by the Masterbatch Industry Network, was grandly held in Dongguan, Guangdong. Representatives from 26 masterbatch companies, including Guangdong Meilian, Yijuyuan, Dongwei Jin, and Huizhou Yongtao, gathered to discuss cutting-edge technologies in petroleum-based carbon black and explore new pathways for win-win supply and demand. Changhong Carbon Black announced that by June 2026, its total production capacity will expand from the current 300,000 tons to 420,000 tons, further solidifying its position as the leading brand of petroleum-based carbon black in China.

High attendance, embarking on a new journey together.

The conference opened with warm applause. General Manager Yao of Dongyi Ningbo, on behalf of the organizers, delivered the opening speech, reflecting on the rapid penetration and reputation accumulation of Changhong Carbon Black in the market since its launch in 2023, particularly in areas such as masterbatches, color pastes, tires, and rubber products. "This achievement belongs to every partner," Yao stated. "Today's meeting is not only a technical seminar but also a gratitude and appreciation event. We hope to build a bridge that brings together upstream and downstream partners, enabling us to make our products better and more competitive."

Customer Voice, Value Verification

Jiangxi Juyan: Secure Carbon Black Quota for Changhong in Advance

Jiangxi JuYan's General Manager Wanwan was the first to take the stage, offering answers with three key words: "supply chain, technology, collaboration." Changhong's 420,000-ton production capacity is a stable supply commitment, petroleum-based carbon black is stable in batches and saves on color adjustment, and JuYan has locked in the carbon black procurement amount for 2026.

Dry goods sharing, technological empowerment

In the subsequent technical seminar session, Liu Xing, Sales Director of Zhejiang Changhong Biomaterials Co., Ltd., Wang Yubao, General Manager of Shenzhen Daxing Chemicals, and Jiao Cuiguang, Engineer at Sino New Materials Research Institute, delivered in-depth reports on three major topics: "Optimization of Dispersion Performance of Petroleum-based Carbon Black in Masterbatches," "High Blackness Low Addition Solutions," and "Green Low-Carbon Additives for Cost Reduction." They provided the attending guests with a knowledge feast filled with "substantial content," covering aspects from raw materials, formulations, and processes to case data.

Capacity expansion, worry-free supply

At the meeting, Ningbo Dongyi officially disclosed the expansion plan for the second phase of Changhong Carbon Black: the new production line with a capacity of 120,000 tons will be gradually put into operation by June 2026, bringing the total production capacity to 420,000 tons. This will effectively alleviate the current situation of supply shortages during peak seasons, providing a "reassurance" for downstream companies to secure raw material supplies.

The successful hosting of this seminar appreciation event not only built a bridge for communication and connection between the upstream and downstream of the masterbatch industry chain but also further enhanced the brand influence of Changhong Carbon Black. In the future, Ningbo Dongyi will continue to play the role of a "link," collaborating with Changhong Carbon Black and industry enterprises to deepen cooperation and contribute to the high-quality development of the masterbatch industry.
