Kima Chemical Co., Ltd. is a leading manufacturer of HPMC (hydroxypropyl methylcellulose) in China. The company has over 20 years of experience in the production of cellulose ethers, including HPMC, and has established itself as a reliable and high-quality supplier of these products. This article will provide an overview of Kima Chemical’s HPMC factory, including its production process, quality control, and applications.

Production Process

Kima Chemical’s HPMC factory is located in Shandong Province, China, and covers an area of 40,000 square meters. The factory has advanced production equipment and technology, as well as a strict quality control system to ensure the production of high-quality HPMC products.

The production process of HPMC involves several stages. The first stage is the preparation of the cellulose, which is obtained from wood pulp or cotton linters. The cellulose is then treated with alkali to remove impurities and to increase its solubility. After the alkali treatment, the cellulose is reacted with propylene oxide and methyl chloride to produce HPMC.

The HPMC produced at Kima Chemical’s factory has a degree of substitution (DS) ranging from 0.1 to 0.3, which means that the HPMC molecules have between 1 and 3 hydroxypropyl groups and between 7 and 11 methyl groups per 100 anhydroglucose units. The DS of HPMC affects its properties, such as its solubility, viscosity, and gelation temperature.

Quality Control

Kima Chemical has a strict quality control system in place to ensure that its HPMC products meet the highest standards. The company has obtained ISO 9001, ISO 14001, and OHSAS 18001 certifications, which demonstrate its commitment to quality, environmental protection, and occupational health and safety.

The quality control process at Kima Chemical’s HPMC factory involves several steps. The raw materials used in the production of HPMC are carefully selected and tested to ensure their quality and purity. The production process is closely monitored to ensure that it meets the required specifications and standards. The finished HPMC products are tested for their viscosity, moisture content, purity, and other properties to ensure that they meet the customer’s requirements.

Kima Chemical’s HPMC products are also subject to rigorous quality control tests conducted by third-party laboratories. These tests include viscosity, particle size distribution, ash content, and heavy metal content. The results of these tests are used to verify the quality of Kima Chemical’s HPMC products and to ensure that they meet the regulatory requirements of different countries and regions.

Applications

HPMC is a versatile and widely used cellulose ether that has many applications in various industries, including construction, pharmaceuticals, food, cosmetics, and personal care. Kima Chemical’s HPMC products are used in a variety of applications, including:

1. Construction: HPMC is used as a thickener, binder, and water retention agent in construction materials such as cement, mortar, and gypsum. HPMC improves the workability of these materials, increases their strength and durability, and reduces shrinkage and cracking.
2. Pharmaceuticals: HPMC is used as a pharmaceutical excipient in tablets, capsules, and other dosage forms. HPMC acts as a binder, disintegrant, and filler in these formulations, and it also improves their stability and bioavailability.
3. Food: HPMC is used as a food additive, particularly in low-calorie and low-fat products. HPMC acts as a thickener, stabilizer, and emulsifier in these products, and it also enhances their texture and mouthfeel.
4. Cosmetics and personal care: HPMC is used in a wide range of cosmetic and personal care products,, including lotions, shampoos, and creams. HPMC acts as a thickener, emulsifier, and stabilizer in these formulations, and it also improves their texture and consistency.
