Frequently Asked Questions

Get answers to the most common inquiries about our paper sizing chemicals.

What is paper sizing and why is it important?

Paper sizing is the treatment of paper fibers with chemicals to reduce liquid absorption. It improves water resistance, printability, strength, and surface quality—critical for packaging, printing, and specialty papers.

Are your chemicals environmentally friendly?

Yes. We offer new environmentally friendly deinking agents and neutral sizing agents that meet modern sustainability standards. Our formulations minimize environmental impact while maximizing performance.

Can you customize formulations for specific paper grades?

Absolutely. Our technical team works closely with clients to develop tailored chemical solutions based on fiber type, machine speed, and end-use requirements.

What is the difference between dry and wet strength agents?

Dry strength agents improve paper strength when dry (tensile, burst, tear). Wet strength agents provide strength retention when the paper is wet—essential for tissues, towels, and food packaging.

Do you supply internationally?

Yes. We serve customers worldwide with reliable logistics and technical support. Our products are used in large paper factories across Asia, Europe, and the Americas.
