High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Deqing Demi Pigment Technology Co., Ltd. is a strategic supplier for the global masterbatch industry. We provide the "Process-Safe" greens required for high-speed plastic production. Our pigments are recognized for their "Consistency in Concentration," allowing masterbatch producers to guarantee exact tinting strength to their end-users. We support the industry with pigments that offer the highest possible heat stability and chemical resistance, ensuring the green stays vibrant from the extruder to the final consumer product.

A: No, as an inorganic mineral, it is stable during the mechanical recycling process and does not degrade the polymer quality.
A: Yes, our "Fine-Grade" green is specifically designed for 20-30 micron films without creating "pinholes" or specks.
We provide "Masterbatch Load Trials" to help our clients determine the maximum possible pigment concentration for their specific carrier resin.
Surface Treatment: We offer surface-modified greens that improve the "wetting" of the pigment by the polymer melt, reducing the energy needed for high-quality dispersion in twin-screw extruders.
In masterbatch science, we focus on the "De-agglomeration Energy." We ensure our green particles are processed to minimize "Van der Waals" forces between crystals. We monitor the FPV (Filter Pressure Value) to quantify the quality of the dispersion. By providing a narrow particle size distribution, we ensure that light is reflected uniformly, resulting in a "Clean" and "Deep" green in the final plastic product, regardless of the thickness of the part.
