Molded Fiber Reinforcement Additive
C101
Bio-based 3D cellulose reinforcement for molded fiber
RETERRA™ C101 is a bio-based, waterborne reinforcement additive based on a novel 3D cellulose structure. Its hierarchical micron/nano architecture strengthens fiber-to-fiber bonding within molded fiber and paper structures, helping improve mechanical performance while reducing linting and dusting.
Product Features
- 01Combines a micron-scale primary structure with nano-scale “whisker” features in a hierarchical 3D cellulose architecture.
- 02Improves fiber bonding and supports higher tensile, burst and interlayer bonding performance.
- 03Improves abrasion resistance while reducing linting and dusting.
- 04Suitable for wood, bamboo, bagasse, reed and recycled-fiber furnishes across wet-press, semi-wet-press and dry-press processes.
Typical Properties
| Item | Specification |
|---|---|
| Appearance | White paste |
| Particle size (D50) | 40 μm |
| pH | 6–8 |
| Solids content | 8% |
| Odor | Odorless |
Applications
- 01Molded-fiber packaging for consumer electronics and personal-care products
- 02Wine, spirits and heavy-duty protective molded-fiber packaging
- 03Specialty paper applications requiring reinforcement and fiber-retention performance
Recommended Use
- 01Addition point: Add after the refining or pulp-preparation stage.
- 02Mixing: No pre-dilution is required. Add in the dilute-stock section and mix thoroughly with the furnish.
- 03Other additives: Compatible with commonly used wet-end additives. Add C101 before other additives where practical.
- 04Applicable pulps: Bamboo, bagasse, reed, wood and recycled pulp; response may vary with furnish and blend ratio.
- 05Recommended freeness: Not recommended for highly refined virgin-pulp systems. Freeness above 400 mL is recommended, with potentially stronger performance in recycled-fiber systems.

Notice
Technical values and application guidance are based on the supplied product data and are intended for product evaluation. Reinforcement response depends on furnish type, blend ratio and process conditions. Users should confirm dosage, compatibility, safety and suitability through application trials before commercial use.
