FennoBond™ products for improved strength and productivity
Our FennoBond dry strength additives are a versatile portfolio of synthetic strength resins for increasing dry strength of paper, board, and tissue grades, as well as molded fiber. Most FennoBond products are cationic or anionic polymers based on polyacrylamide chemistry and can be applied either in the wet end or added as sheet spray application.
- Engineered celluloce additive (ECA)
- Amphoteric polyacrylamide
- Cationic glyoxalated polyacrylamide (GPAM)
- Cationic solution polyacrylamide (C-SPAM)
- Cationic dispersion polyacrylamide (Micropolymer)
- Anionic solution polyacrylamide (A-SPAM)
Depending on grade requirements and the process, several FennoBond products can be utilized or combined into dual strength systems.
Strength types improved by FennoBond products:
- Tensile
- Burst
- Compression (SCT, RCT, CMT, CCT)
- Stiffness
- Internal (Scott bond)
- Surface (lint or dust reduction)
Benefits from dry strength increase
You can utilize extra strength gained from using FennoBond dry strength additives in multiple ways, depending on your production targets.
| Trade-off strength | Produce lower grammage (fiber and steam savings, improved mchine speed) |
| Reduce refining (energy savings, less dust) | |
| Reduce chemical consumption (wet strength resins, starch, retention polymers) | |
| Substitute fibers with cheaper fibers or fillers | |
| Keep strength | Upgrade quality or avoid overweighting |
| Improve machine runnability | |
| Improve converting efficiency | |
| Increase productivity and dewatering |
