Key Features and Chemical Properties

Indigo Blue Vat Blue is renowned for its stability and resistance to fading under normal conditions. Its sublimation point ranges between 390–392°C (734–738°F), making it suitable for high-temperature industrial processes. Despite its insolubility in water, it dissolves effectively in solvents like DMSO and chloroform, enabling versatile application methods. These properties align with the National Institute of Standards and Technology (NIST) guidelines for chemical stability and solubility testing, ensuring compliance with global quality benchmarks.

Industrial Applications and Usage

The primary application of Indigo Blue Vat Blue lies in the textile industry, particularly in the production of denim for blue jeans. On average, a single pair of jeans requires 3–12 grams of the dye. Its ability to withstand processes like stone washing and acid washing makes it a preferred choice for achieving the iconic faded look of denim. Additionally, smaller quantities are used for dyeing wool and silk, showcasing its versatility across different fabrics.

According to the NIST, chemical dyes must meet stringent criteria for colorfastness and durability. Indigo Blue Vat Blue's performance in these areas is well-documented, with studies highlighting its resistance to UV degradation and mechanical stress, as outlined in NIST publications on textile chemistry.

Packaging and Logistics

The product is available in multiple packaging options to suit different logistical needs:

• 20kg cartons: 9 metric tons (without pallet) in a 20' GP container111; 18 tons (with pallet) in a 40' HQ container111.
• 25kg bags: 12 metric tons in a 20' GP container111; 25 metric tons in a 40' HQ container111.
• 500–550kg bags: 20–22 metric tons in a 40' HQ container111.

These packaging solutions ensure efficient transportation and storage, minimizing waste and optimizing supply chain operations. Anping County Wuxin Chemical Dye Co., Ltd. emphasizes compliance with international shipping standards, as outlined in NIST guidelines for chemical logistics.

Storage and Handling Guidelines

To maintain the integrity of Indigo Blue Vat Blue, proper storage is critical:
