Technical Exchange on Paper Chemicals: Advancing Paper-Grade CMC and CMS Innovation

Introduction

In the rapidly evolving paper industry, the demand for high-performance and sustainable paper chemicals continues to grow. To address technical challenges and explore new development opportunities, Hunan Sentai Biotechnology Co., Ltd. recently held a high-level technical exchange seminar with the China Pulp and Paper Research Institute

This collaboration highlights the importance of innovation in paper-grade sodium carboxymethyl cellulose (CMC) and sodium carboxymethyl starch (CMS)—two critical functional additives widely used in modern papermaking.

In-Depth Technical Exchange Between Industry Leaders

On March 18, 2026, a delegation of senior experts from China Pulp and Paper Research Institute visited Hunan Sentai for an in-depth discussion on the R&D and production of paper-grade CMC and CMS.

Both sides conducted comprehensive exchanges focusing on:

• Optimization of CMC and CMS production processes

• Improvement of quality control systems

• Identification of technical bottlenecks in papermaking additives

• Exploration of next-generation functional additives for paper industry

By combining Sentai’s practical manufacturing experience with China Pulp and Paper Research Institute’s advanced research capabilities, the seminar created a strong foundation for future innovation.

Key Challenges in Paper-Grade CMC and CMS Development

As essential cellulose derivatives in papermaking, CMC and CMS play critical roles in:

• Surface sizing

• Coating performance

• Paper strength enhancement

• Retention and drainage improvement

However, manufacturers often face several challenges:

1. Product Stability and Consistency

Ensuring uniform viscosity and substitution degree in sodium carboxymethyl cellulose for paper industry is crucial for stable performance.

2. Process Optimization

Efficient production of sodium carboxymethyl starch (CMS) requires precise control over reaction conditions and raw material quality.

3. Cost vs Performance Balance

Replacing imported products with locally produced paper-grade CMC and CMS while maintaining high performance remains a key industry goal.

During the seminar, these issues were addressed through targeted technical discussions and practical case analysis.
