1. Who manufactures cellulose ether?

At present, the main cellulose ether manufacturers in the world include Ashland, Dow, Lotte, and Shandong Head. Cellulose ethers are water-soluble polymers produced by chemically modifying cellulose. The main examples of cellulose ethers include CMC, MC, and derivatives such as HPMC, HEMC, and HEC.

In this article, we will mainly introduce Dow and Mikem. Both Mikem and Dow are cellulose ethers manufacturers. Dow Chemical is one of the top three chemical producers in the world. Mikem Chemical is a leading  cellulose ethers manufacturer and supplier in the world.

1.1 Dow chemical

Founded in 1897, Dow Chemical is a multinational corporation in the United States. Headquartered in Midland, Michigan, USA. It is one of the world's three largest chemical manufacturers. Dow Chemical is a producer and supplier of raw materials for products in the electrical, automotive, agricultural, chemical processing, electronics, natural gas, and processed foods industries. At the beginning of its establishment, it only sold bleach and potassium bromide.

Dow Chemical's product range is also expanding, including cellulose ethers, re-dispersible latex powders, acrylic polymer emulsions, silicon, synthetic thickeners, Dispersants, and Opaque Polymers. Used in construction, cosmetics, and pharmaceutical industry.

1.2 Mikem chemical

cellulose ether manufacturers mikem

Mikem was founded in 2021 and is headquartered in Dallas, USA. The headquarters is mainly responsible for product research and development and quality inspection. Mikem has focused on the production of cellulose ethers including HPMC, HEMC, HEC, re-dispersible latex powder, and concrete fibers since the beginning. Concrete fiber reinforced materials including PP fiber, steel fiber, and polyvinyl alcohol fiber. It is in a leading position in the production and supply of cellulose ether. Mainly used in construction and detergente industries. Through communication with customers, the U.S. R&D department constantly adjusts and optimizes the formula to develop more applicable products.

As cellulose ether manufacturer, we also have equal grade HPMC. In the production process of hydroxypropyl methylcellulose, the methoxy content of the hydroxypropyl methyl cellulose produced by Mikem is 19-24%. And the hydroxypropyl content is 4-12%. Generally speaking, the higher the methoxy content, the greater the viscosity and the better the water retention effect. The R&D department has designed a variety of HPMCs to meet market demand, such as MelaColl MP45000 and MP70000. The difference between the two is that the viscosity of MP70000 is 65000-75000, and the viscosity of MP45000 is between 40000-55000. In addition, MP45000 has a medium level of final consistency, anti-sagging, and thickening effect. In these aspects,  MP75000 is better than MP45000.

4. How to find good Chinese cellulose ether manufacturers

If you want to find  good cellulose ether manufacturers in China, you may be more concerned about the quality, price, capacity, and whether the cellulose ether manufacturer is a real, trader or manufacturer.

Are you a manufacturer or a trader: Most Of Chinese cellulose ether manufacturers are located in Shandong and Hebei. They all have their own supply chain systems. I have a very simple way of determining whether it is a manufacturer or not. The average manufacturer offers much less product than a supplier. Hope this little way can help you.

Capacity problem: Many cellulose ether buyers like to stock up on Dow, Lotte, and Estée because their production capacity is relatively large, they can provide a stable supply of goods, and can quickly stock up and ship. The annual production capacity respectively are 100,000 tons, 40,000 tons. 8,000 tons.

China can get such a level, known as Shandong Head, 37,000 tons. At present, Heda mainly specializes in high-end fields, especially pharmaceutical grade, and food grade cellulose ether production. Shandong Mikem provides construction-grade cellulose ether with an annual production capacity of about 50,000 tons.

Price problem: You must know that prices abroad are generally higher than at home. The price in Hebei, China, is lower, but there are also certain quality problems.

Quality issues: Speaking of cellulose ether manufacturers in China, you must be worried about the quality of products at Alibaba, especially small and medium-sized enterprises in Hebei. Mikem is an American brand that is able to offer high-quality cellulose ether products.
