We are a comprehensive supplier of high-end polyether polyols.
Within the polyurethane industry, polyether polyols and their premixes are commonly referred to as the "white component". Dongda’s "White-Tech" stands for innovative raw-material technologies centered on high performance, green low-carbon solutions, cleanliness and safety — the key technologies that deliver safer, purer and longer-lasting products for daily life.
As technology advances, polyether polyols have been deeply integrated into a wide range of production and living scenarios. Charming Sinochem Dongda launches the column 【Dongda’s "White-Tech"】to unveil diversified application scenarios of polyether polyols, interpret core product features, and explore the hidden technological power around us, experiencing how innovation empowers a better life.
You may simply have picked the wrong "skeleton".
Foam is a hidden nuisance in industrial production. Generated during stirring, crushing, fermentation, boiling, cleaning, filtration and other processes, foam is widely seen in processing-liquid tanks, petrochemical workflows, industrial and agricultural formulations, industrial cleaning baths, food-processing workshops and many other settings. Excessive foam wastes equipment capacity, reduces production efficiency, impairs finished-product quality and causes defects.
Polyethers are important non-ionic surfactants. Polyethers with specific molecular structures deliver excellent defoaming and foam-inhibition performance, and are widely used in pharmaceutical, food, chemical, textile and other industries. As silicone-free additives, polyether-based defoamers take functional polyether as their core component. By tuning their molecular-chain structure, they achieve efficient foam breaking and long-term foam suppression. Compared with silicone-based defoamers, polyether variants leave no silicone speck residues and exhibit outstanding stability under high-temperature, strong-alkaline and fermentation conditions.
(1) Efficient Foam Breaking & Suppression with Superior Defoaming Performance Designed via precise formulation systems, the products rapidly penetrate and eliminate bubbles of all sizes to instantly remove accumulated foam. They also durably inhibit foam regeneration, addressing foaming issues throughout production from the source with thorough, stable defoaming suited for continuous industrial workflows.
(2) Low-VOC, Low-Odor and Environment-Friendly Compliance Carrying forward Sinochem Dongda’s commitment to green R&D, our products strictly control harmful-impurity residues, featuring low volatility and no pungent odor. They meet environmental standards for industrial production and safety requirements for high-end coating and skin-contact articles, ideal for clean, high-end manufacturing scenarios.
(3) Excellent Compatibility without Impairing Downstream Processes Boasting chemically inert molecular structures, the products rarely react with raw materials in working systems and do not alter the pH, viscosity, color or fundamental properties of materials, making them suitable for complex formulation systems.
(4) Broad Process Adaptability and Consistent Batch-to-Batch Quality With a wide operating process window, the products fit industrial workflows across pharmaceuticals, food, chemicals, textiles and other sectors, offering high production tolerance. Full-process quality control minimizes performance fluctuations between batches, delivering stable quality to support large-scale manufacturing.
Sinochem Dongda supplies multiple product lines including GP-type and GPE-type defoamers, fatty-alcohol polyoxypropylene-polyoxyethylene ethers, vegetable-oil-modified polyethers and more. These stable, hard-to-decompose, non-toxic products disperse easily in foaming media. They are widely applied in pharmaceutical manufacturing, papermaking, sugar refining, fertilizer production, printing-dyeing, petrochemical processing, wastewater treatment and other industries.
For biological-fermentation workflows, our defoamers overcome the demulsification risk of silicone-based defoamers under high temperatures, facilitating membrane filtration and downstream extraction. They are suitable for foam elimination and suppression during microbial fermentation of glutamic acid, citric acid, lysine, leucine, arginine, diacids, oxytetracycline, neomycin, chlortetracycline, abamectin, colistin, spinosad, Vitamin C, Riboflavin, Coenzyme Q10, erythritol, yeast and other substances.
We drive application upgrading through raw-material innovation and expand industrial boundaries with specialty polyethers. Prioritizing scientific-technological innovation and premium-quality philosophy, Sinochem Dongda builds a diversified application portfolio, empowering every step forward with professionalism and ingenuity.
