Product Description：

Properties and Usage:

Isophthaloyl chloride, an aromatic acyl chloride compound, is used in the synthesis of high-performance polymers, liquid crystal materials, and other chemical intermediates.

Applications:

1. Polymer production:

Polyesters and polyamides: Isophthaloyl chloride is widely used as a monomer in the production of high-performance polymers, including polyesters and polyamides. These materials are used in fibers, films, and engineering plastics.

Aramid fiber: It is a key component in the synthesis of aromatic polyamide fibers (such as Kevlar), which are known for their high strength and heat resistance and can be used in bulletproof vests, aerospace applications, and other harsh environments.

2. Coatings and resins:

Thermosetting resins: Isophthaloyl chloride is used to produce thermosetting resins, which are used in coatings, adhesives, and composites. These resins are durable and heat-resistant and chemical-resistant.

3. Other applications:

Medicine: It can be used as a chemical intermediate for the synthesis of pharmaceutical compounds.

Dyes and pigments: Isophthaloyl chloride is also used in the production of certain dyes and pigments, helping to improve the stability and performance of colorants.

4. Anti-corrosion coatings: Due to its ability to react with a variety of functional groups, isophthaloyl chloride is also used as a cross-linking agent in the production of high-performance anti-corrosion coatings to improve the durability and corrosion resistance of the coating.

Storage conditions: Store in a cool, dry, well-ventilated warehouse. Keep away from fire and heat sources. Avoid direct sunlight. Package tightly. Store separately from alkalis, oxidants, alcohols, etc. and avoid mixing. Equip with appropriate types and quantities of fire-fighting equipment. The storage area should be equipped with appropriate materials to contain leaks.

Packing: This product is packed in 25kg 100kg 200kg cardboard drums, and it can also be customized according to customers' requirements
