Starch ether

Starch ether is an etherified starch produced by the reaction of hydroxyl groups in starch molecules with reactive substances. It is a green and environmentally friendly modified chemical raw material, typically appearing as a white powder, and possesses excellent water retention, thickening, lubricating and stabilising properties. The ether bonds are resistant to hydrolysis in both acidic and alkaline environments, and the product has a wide range of applications. It is extensively used across multiple industries, including construction, food, pharmaceuticals, textiles and oil drilling, serving as a key raw material for optimising product performance and reducing production costs. As a specialist energy and chemical enterprise, Jiurunfa Chemical Technology Co., Ltd. has been deeply involved in the chemical sector for many years. Relying on mature technology and stringent quality control, the company produces high-quality starch ether products that precisely meet the needs of various industries, helping businesses to improve quality and enhance efficiency.

Starch ether is produced using natural starch as the raw material, undergoing multiple processes including etherification, neutralisation, washing, drying and grinding. The production process demands a high degree of precision and technical expertise; traditional production methods are prone to issues such as poor product uniformity and insufficient degree of substitution. Leveraging the robust technical support and close collaboration with Beijing Chemical Industry Group, Jiurunfa has optimised the starch ether production process. By adopting a modified organic solvent method using ethanol as a dispersant and precisely controlling reaction temperature and duration, the company has enhanced product substitution levels and uniformity, ensuring its production technology remains at the forefront of the domestic industry.

As different industries have varying requirements regarding the performance and specifications of starch ether, Jiurunfa has developed a diversified range of starch ether products in response to market demand. This range covers multiple categories, including hydroxypropyl starch ether and carboxymethyl starch ether, enabling precise adaptation to various industry applications. In the construction sector, starch ether is used in dry-mix mortars, fillers and tile adhesives, where it rapidly thickens the mixture, improves water retention and prevents sagging, optimises workability, reduces material wastage and minimises the risk of subsequent cracking. In the food industry, it serves as a thickening and texturising agent, enhancing the taste and texture of food products and improving overall quality.

In the pharmaceutical sector, starch ether can serve as an excipient and disintegrant, meeting the requirements of pharmaceutical formulation production; in the textile sector, it can replace traditional raw materials, enhancing the film-forming properties and permeability of sizing agents, thereby optimising textile product quality; in the oil drilling sector, it can be used as a water loss reducer to protect oil reservoirs from contamination and improve drilling efficiency. With its professional R&D team, Jiurunfa can provide customised starch ether products tailored to specific user requirements, meeting the individual needs of various applications.

Jiurunfa oversees, controls and manages every stage of starch ether production, implementing rigorous quality control throughout the entire process—from raw material procurement and manufacturing to finished product testing—to ensure product quality remains stable and reliable, with all technical specifications meeting industry standards. The company boasts a professional team comprising several PhDs and Masters, responsible for product R&D and process optimisation, continuously enhancing the quality and production efficiency of starch ether products.

When selecting starch ether, quality, compatibility and value for money are key considerations. Jiurunfa not only possesses mature starch ether production technology and a diverse range of product specifications, but also boasts a comprehensive sales and service system. The company holds its own import and export rights, with products exported to dozens of countries and regions, enjoying an excellent international reputation; backed by technical support from the Beijing Chemical Industry Group, it continuously optimises product performance and can provide rapid delivery and customised services. By choosing Jiurunfa’s starch ether, you gain access to high-quality, cost-effective green chemical raw materials whilst benefiting from professional pre-sales consultation and after-sales support. Leveraging Jiurunfa’s capabilities and reputation, we help businesses reduce production costs, enhance product competitiveness, and achieve mutually beneficial cooperation.
