1. What is Dry Strength Agent?

Dry strength agent is an important functional chemical in paper production that improves the mechanical strength of paper without affecting its whiteness or printability. Its mechanism enhances the bonding between cellulose fibers, making the paper stronger, more durable, and less prone to tearing during production or use.

2. The Role of Dry Strength Agent in Paper Production

In the papermaking process, cellulose fibers are bonded by hydrogen bonds. However, at high production speeds and with diluted pulp, these bonds are often insufficient. This is where dry strength agents become essential:

  -   Increase the tensile strength and tear strength of paper.

  -   Improve folding ability, toughness, and surface smoothness.

  -   Reduce the need for high-grade pulp by efficiently utilizing recycled or low-refined pulp.

  -   Enhance retention and forming efficiency, ensuring a more stable production process.

3. Benefits of Using CRM Technology’s Dry Strength Agent

With years of experience in supplying functional chemicals for the paper industry, CRM Technology has developed the DS-1216 dry strength agent with outstanding advantages:

  -   Significantly increases dry strength even at low dosages.

  -   Does not affect wettability or printability.

  -   Highly compatible with AKD, cationic starch, PAC, and other polymers.

  -   Suitable for various types of paper: printing paper, packaging paper, tissue, duplex, and recycled paper.

The product is designed to optimize cost-effectiveness and production performance, helping mills improve paper quality while maintaining economic efficiency.

4. Applications of Dry Strength Agent

Dry strength agents are commonly used in:

  -   Printing paper, writing paper, photocopy paper.

  -   Packaging paper and cartons.

  -   Tissue, paper towels, and toilet paper.

  -   Recycled paper or any paper requiring high mechanical strength.

Thanks to its ability to enhance strength and product stability, dry strength agent is considered an indispensable key in modern paper production.

5. Optimizing Usage Efficiency

To achieve the best results, dry strength agents should be used under the following conditions:

  -   Papermaking pulp pH: 6.5 – 8.0

  -   Recommended dosage: 0.3 – 1.0% of dry pulp weight

  -   Dosing point: before the headbox or at the starch blending system

CRM Technology is always ready to provide detailed technical consultation, helping customers select the proper dosage and operating conditions for each type of paper product.
