1. Tear‑prone & Low‑strength Paper? Choose PAM Paper‑Strengthening Agent
Many paper mills face quality issues: insufficient tensile strength, easy tearing and unsatisfactory ring crush strength.
Polyacrylamide (PAM), a paper‑strengthening agent, effectively improves bonding force between paper fibers. It boosts physical paper strength and lowers paper breaks and defective products. This high‑efficiency auxiliary helps upgrade paper quality and sharpen market competitiveness.
2. Main Causes of Poor Paper Strength
Weak bonding between fibers, heavy loss of fine fibers and poor interlayer bonding mainly lead to low paper strength.
When using waste paper pulp or straw pulp, raw fiber quality stays mediocre. Fibers hardly meet strength requirements through natural bonding alone. Special strengthening agents improve internal fiber bonding and raise overall paper strength.
3. How Polyacrylamide Improves Paper Strength
PAM carries active groups on its molecular chains. These groups form hydrogen bonds with fibers and tightly bind loose fibers together.
It cuts fine‑fiber loss and builds denser, more even paper layers. In this way, it greatly raises tensile strength, burst resistance, ring crush strength and stiffness for tougher finished paper.
4. Cationic PAM Delivers Better Strengthening Performance
Cationic polyacrylamide is widely used for paper strengthening. It features strong affinity for negatively‑charged fibers and achieves even adsorption without excessive flocculation.
It strengthens paper while preserving good paper formation. It works remarkably well for waste‑paper‑based paper, packaging paper and paperboard. It improves ring crush strength and burst performance, and produces high‑strength paper even with low‑grade pulp.
5. Strengthening Plus Retention & Drainage Benefits
PAM brings both strengthening and retention‑aid & drainage‑aid functions.
It retains more fine fibers and fillers to reduce raw‑material loss. It also speeds up dewatering on the wire section, raises paper machine speed and reduces web breaks. One agent serves multiple purposes. It improves strength and production efficiency with high cost‑effectiveness.
6. Wide Paper‑grade Compatibility & Easy Dosing
This PAM strengthening agent fits packaging paper, paperboard, cultural paper and tissue paper.
Dissolve it at the set ratio and feed it continuously into the pulp system. The operation is simple. It does not harm paper brightness or printability, and causes no equipment corrosion. Operators can master the process quickly. It generates fast returns with low input.
7. Better Quality & Lower Costs for Higher Overall Profit
PAM strengthening allows mills to use more waste paper pulp and cut consumption of high‑cost wood pulp for lower raw‑material expenses.
Higher paper strength reduces defective rates and transportation damage. It brings outstanding comprehensive economic benefits and serves as an ideal option for paper mills to upgrade quality, cut costs and lift productivity.
