Kunshan Midstar Dyestuff Chemical Co., Ltd., established in 1997 and located in the Kunshan Economic & Technological Development Zone, Jiangsu Province, is a professional integrated service provider of coloring materials, combining in-house manufacturing, channel distribution, and cross-border trade.

The company is specialized in the R&D and supply of solvent dyes, organic pigments, nano color pastes, and specialty auxiliaries. Our products are widely used in plastics, synthetic fibers and textiles, packaging, printing inks, industrial coatings, artificial leather, pesticides, oil products, and electronic chemicals, among other fields.

To strengthen its pigment post-treatment and fine-processing capabilities, the company established Kunshan Sun Color Pigments Co., Ltd. in 2001 as a dedicated production base. The two affiliated factories operate in synergy, forming a diversified product portfolio. With hundreds of standardized products currently available, the company is able to meet varied coloring requirements across multiple industries and application scenarios.

Quality has always been the cornerstone of Midstar. The company has introduced a full set of precision physicochemical testing instruments and established a comprehensive quality control system covering the entire process from raw material intake to finished product dispatch. Leveraging nearly three decades of industry application experience, the company can provide customized coloring solutions tailored to specific customer operating conditions, addressing requirements such as heat resistance, migration resistance, and high dispersibility.

While deeply cultivating the domestic market, we are also actively expanding our global presence. Our products are exported to Europe, the Americas, Japan, South Korea, Southeast Asia, Hong Kong, Macao, and Taiwan, and we have long served over 1,000 corporate clients both domestically and overseas, earning broad trust with our consistent quality.

To coordinate international business and deepen its global footprint, the company established Shanghai Youxiang International Trade Co., Ltd. in 2014, dedicated exclusively to import and export operations. Leveraging its own production bases and close collaboration with multiple upstream factories, the company integrates a complete industrial chain encompassing dyes, pigments, color masterbatches, inks, and chemical intermediates. It provides continuous and stable raw material supply services to global customers in industries such as plastics, electronics, pharmaceuticals, and printing.

In terms of corporate culture, the company consistently adheres to the corporate spirit of "integrity in business, pragmatism and innovation," remains customer-centric, and upholds the philosophy of people-orientation and harmonious coexistence. We are committed to continuously creating long-term value for customers, employees, and shareholders, and to working closely with industry partners in sincere collaboration for shared growth.
