Application areas of sodium hydrosulfite

Sodium hydrosulfite is widely used in the textile industry for its reducing dyeing, reducing cleaning, printing, and bleaching, as well as for bleaching silk, wool, and nylon fabrics. Because it contains no heavy metals, fabrics treated with it retain vibrant colors and are less prone to fading. Furthermore, sodium hydrosulfite is used for bleaching food products such as gelatin, sucrose, and hone

Natural Lutein Used in Animals Feed

Natural lutein is yellow-orange powder with extremely strong coloring power. It is mainly used in poultry and aquaculture industries for coloring poultry skin, egg yolks, and shanks. Because animals cannot synthesize lutein themselves, they can only absorb lutein from feed and the colors deposited in their bodies

Reasons for Price Volatility in Polymer Polyol (POP)

POP（Polymer Polyol） is a polyurethane intermediate; its cost is heavily tied to crude oil-based chemical feedstocks, and it is characterized by highly cyclical downstream demand, low supply elasticity, and frequent disruptions from trade and policy factors. The convergence of these elements leads to significant price swings and rapid market shifts.

Key Drivers of TCCA Price Increases

The price of cyanuric acid, the main raw material, is drastically affected by the tight supply of upstream urea. Global urea production capacity is expected to decrease by approximately 8% in 2026 due to geopolitical conflicts, pushing cyanuric acid prices from RMB 800/ton to RMB 1100/ton (an increase of 37.5%), directly leading to an increase in the proportion of production costs from 55% to 65%.

Ethylene Glycol Moisture content and color are critical factors in ink productio

In ink formulations, Ethylene Glycol primarily serves as a high-boiling-point solvent. For colored inks—particularly those in lighter shades—solvent color (measured on the Pt-Co scale) is crucial; even slight yellowing can cause color shifts in the final printed product.

HPMC as a Dispersant in Building Finishing

HPMC, as a dispersant, thickener, and binder in building finishing, is primarily used in the molding of cement mortar and gypsum products. It is used in cement mortar to increase its adhesion, reduce flocculation, improve viscosity and shrinkage, and maintain moisture retention. It reduces moisture loss from concrete surfaces, increases strength, and prevents cracking and weathering caused by wate

China's Sulfuric Acid Price Shake the Global Market

On April 10, 2026, China officially released new regulations, comprehensively restricting the export of ordinary smelting by-product sulfuric acid and industrial sulfuric acid from May 1st. Only high-end electronic-grade high-purity sulfuric acid can be exported in small quantities. Recently, sulfuric acid prices have surged dramatically, exceeding 130%. No one expected that this seemingly ordinar

Performance Comparison of ATMP and HEDP

ATMP (Aminotrimethylenephosphonic acid) and HEDP (Hydroxyethylidene diphosphonic acid) are both commonly used organophosphonic acid scale inhibitors and corrosion inhibitors, widely applied in water treatment. Each has its own characteristics, and their effectiveness depends primarily on the specific application scenario and requirements. The following is a comparison of their performance:
