⭐⭐⭐⭐⭐ James Lin - Textile Production Manager
"We’ve been using the XCWY Sulphur Black BR 200 Base Model in our garment manufacturing line since February , and the dyeing efficiency has been outstanding. Our cycle times dropped from 60 to 45 minutes per batch, and colorfastness after 50 washes is still near perfect. It’s more cost-effective than reactive dyes without sacrificing quality."Purchase Date: February | Usage Period: 5 months
⭐⭐⭐⭐⭐ Elena Martinez - Independent Textile Artist
"I bought the Advanced Model for my small-batch fabric dyeing projects, and I’m blown away by how smooth and consistent the black tones are. The ultra-fine 3–5 µm particles mix evenly in my solutions, with zero clumping. Perfect for hand-dyed scarves and art prints. Plus, cleanup is easy!"Purchase Date: November | Usage Period: 8 months
⭐⭐⭐⭐☆ David Park - R&D Chemist, EcoInk Solutions
"We integrated the Pro Model into our conductive ink prototypes for printed electronics. The adjustable conductivity and sub-3µm particle size make it ideal for inkjet compatibility. Fade resistance and chemical stability exceed our benchmarks. Only downside? The shelf life is shorter than expected—must rotate stock frequently."Purchase Date: April | Usage Period: 7 months
⭐⭐⭐⭐⭐ Anita Patel - Founder, Urban Hide Studio
"Switched from azo dyes to Sulphur Black BR 200 (Base Model) for our leather bags and wallets. The color depth is richer, and because it’s pH-neutral, we’ve seen far less surface cracking. Our customers consistently comment on the long-lasting black finish—even after years of use."Purchase Date: January | Usage Period: 6 months
⭐⭐⭐⭐⭐ Tomas Reed - Paper Mill Operations Lead
"Used the Base Model in our paper coating line starting October . High concentration means we use less dye per ton, reducing costs significantly. The fast absorption ensures uniform black across high-speed rollers. Also appreciates that it meets FDA standards for packaging applications."Purchase Date: October | Usage Period: 9 months

"Sulphur Black BR 200 sets a new benchmark in sulfur dye performance. Its BR 200-grade dyeing power, combined with REACH and RoHS compliance, makes it a top-tier choice for sustainable, high-volume textile producers aiming for deep blacks without environmental compromise."
Markus Weber - Industrial Additives Consultant
"In plastic coloring, dispersion and thermal stability are critical. The granular form and 5–10 µm particle size of the Base Model integrate seamlessly into polymer melts during extrusion. For high-end applications, the Pro Model’s triple chemical resistance is unmatched in the current market."

Sulphur Black 200 Specification
Pay Attention
Sulphur black 200 has hygroscopicity. In the process of storage and transportation, it must be sealed and packed to avoid dampness, caking and deterioration. It should be kept cool and ventilated to prevent direct sunlight and near fire. It should be loaded and unloaded lightly to prevent falling and collision..
