Main Applications of Acrylonitrile

Acrylonitrile is primarily used as a raw material and chemical intermediate in the polymer and chemical industries.

1. Acrylic Fibers

One of the major applications of acrylonitrile is the production of acrylic fibers. Polyacrylonitrile-based fibers are widely used in textiles and can provide properties such as strength, weather resistance, and chemical resistance.

2. ABS Resins

Acrylonitrile is an important component in the manufacture of ABS (acrylonitrile-butadiene-styrene) resins. ABS is widely used for automotive components, electrical and electronic products, appliances, and consumer goods.

3. Nitrile Rubber

Acrylonitrile is also used in the production of nitrile butadiene rubber (NBR). NBR is valued for its resistance to oils, fuels, and many chemicals and is used in seals, hoses, gaskets, gloves, and other industrial products.

4. Chemical Intermediates

Acrylonitrile is further processed into various chemical intermediates, including compounds used in the production of resins, plastics, fibers, and specialty chemicals.

Packaging and Storage

Acrylonitrile is a flammable and toxic chemical and requires appropriate handling during transportation, storage, and use. It should be stored in a cool, well-ventilated area away from heat, ignition sources, and incompatible materials.

Commercial transportation and packaging should comply with applicable dangerous-goods regulations. The specific packaging method, storage conditions, and transportation requirements should be confirmed according to the latest SDS, local regulations, and shipping requirements.

Why Is Acrylonitrile Important?

Acrylonitrile plays an important role in modern chemical manufacturing because it is used across several major industries. Its applications in acrylic fibers, ABS resins, nitrile rubber, and chemical intermediates make it an important raw material for the plastics, textile, automotive, electronics, and industrial sectors.

For industrial purchasing, customers generally consider factors such as purity, product specifications, packaging, origin, loading quantity, delivery terms, and required documentation when sourcing acrylonitrile.

Conclusion

Acrylonitrile (CAS No. 107-13-1) is an important chemical intermediate with extensive applications in the production of acrylic fibers, ABS resins, nitrile rubber, and other chemical products. Its combination of reactivity and industrial versatility makes it an essential raw material for various downstream manufacturing industries.
