Alkenyl succinic anhydride (ASA) is a reactive sizing agent that can impart good water repellence to paper by decreasing the wettability of the cellulose fibers.
Alkenyl Succinic Anhydrides(ASA) CAS NO.32072-96-1/28777-98-2
is an important organic chemical raw material widely used in the papermaking industry and other fields.
I. Definition and Properties
Definition:Alkenyl Succinic Anhydrides (ASA) refer to a class of unsaturated hydrocarbons containing succinic anhydride groups. They exhibit high reactivity and exceptional sizing performance.
Properties:ASA offers significant advantages, including low dosage requirements, broad pH adaptability, rapid development of sizing effects, and no adverse impact on paper’s static friction coefficient. Additionally, it is compatible with CaCO₃ fillers, enhancing paper strength and durability.
II. Application Fields
Papermaking Industry:
- Neutral Sizing Agent: ASA serves as a key neutral sizing agent in papermaking, improving water resistance, tensile strength, abrasion resistance, and brightness of paper. Compared to traditional rosin-based acidic sizing, ASA significantly enhances paper quality while protecting papermaking equipment and the environment.
- Broad Applications: ASA is increasingly used in higher-value-added paper grades such as coated base paper, offset paper, tipping base paper, stamp paper, and dictionary paper. With the growing adoption of neutral sizing technology, ASA’s market share in China’s internal neutral sizing agent market is steadily expanding.
Other Fields:ASA also functions as a water repellent for leather and textiles, demonstrating its versatile application potential.
III. Market Outlook
Driven by the development of the paper industry and the widespread adoption of neutral sizing technology, Alkenyl Succinic Anhydrides (ASA) — as an efficient and eco-friendly sizing agent — holds promising market prospects. It is expected to capture an increasingly significant share in the global neutral sizing agent market for pulp applications.
