How to Improve NBR Properties?
Additives play a crucial role in enhancing NBR’s properties, which can provide additional functionalities and improve specific characteristics. Here’s how additives can be used:
- Plasticizers: These additives increase the flexibility and softness of NBR, making it easier to process. Plasticizers also help lower the polymer’s glass transition temperature.
- Antioxidants: Added to NBR formulations to prevent premature aging and degradation, thereby extending the service life of NBR products.
- Fillers: Fillers such as carbon black, silica, and calcium carbonate are commonly used to reinforce NBR. These fillers enhance tensile strength, tear resistance, and abrasion resistance.
- Processing Aids: These additives make nitrile material easier to process and have higher productivity during manufacturing.
When selecting additives to improve, several key considerations should be considered such as chemical compatibility, functional compatibility, physical form, synergistic effects, etc.
