HPMC Manufacturer | Hydroxypropyl Methylcellulose Supplier 

Introduction

As the leading HPMC manufacturers and HPMC suppliers in the world, Kima Chemical stands out for its commitment to HPMC quality, innovation, and customer satisfaction.Hydroxypropyl Methylcellulose (HPMC) has emerged as one of the most versatile and widely used cellulose ethers in various industrial sectors. From construction and pharmaceuticals to food and cosmetics, HPMC provides critical functionality due to its unique chemical properties. 

KimaCell® provides a comprehensive overview of HPMC, its uses, manufacturing process, quality control standards, and why Kima Chemical is regarded as a premier HPMC supplier in the global market.

Chapter 1: What Is HPMC?

1.1 Definition

Hydroxypropyl Methylcellulose (HPMC), also known as hypromellose, is a semi-synthetic, inert, viscoelastic polymer. It is derived from natural cellulose and chemically modified to create a multifunctional compound used in various applications.

1.2 Chemical Composition

HPMC is made by reacting cellulose with methyl chloride and propylene oxide, replacing some of the hydroxyl groups in the cellulose molecule with methoxy and hydroxypropyl groups. These modifications enhance its solubility, thermal stability, and film-forming abilities.

1.3 Properties

• Solubility: Soluble in cold water

• Viscosity: Ranges from low to high depending on molecular weight

• pH Stability: Stable across a pH range of 3–11

• Non-toxic: Safe for pharmaceutical and food use

• Thermal Gelation: Forms gels upon heating

Chapter 2: Applications of HPMC

2.1 Construction Industry

HPMC is extensively used in construction due to its water retention and thickening properties. Common applications include:

• Tile adhesives

• Cement-based mortars

• Self-leveling compounds

• Plasters

• Gypsum-based products

2.2 Pharmaceuticals

In the pharmaceutical industry, HPMC is used as:

• Binder and film-coating agent for tablets

• Controlled-release agent

• Capsule shell alternative for vegetarians

2.3 Food Industry

As a food additive, HPMC serves as:

• Thickener

• Emulsifier

• Stabilizer

• Fat replacer in low-fat products

2.4 Cosmetics and Personal Care

• Lotions and creams

• Shampoos and conditioners

• Toothpaste thickener

2.5 Paints and Coatings

• Improves viscosity and workability

• Enhances pigment suspension

Chapter 3: HPMC Grades and Specifications

3.1 Viscosity Grades

HPMC is available in a wide range of viscosities, from 5 mPa·s to over 100,000 mPa·s. The choice depends on the intended application.

3.2 Substitution Type

The ratio of methoxy to hydroxypropyl groups affects the polymer’s properties:

• Higher methoxy: Greater gelling temperature

• Higher hydroxypropyl: Improved solubility

3.3 Surface Treated vs. Non-Surface Treated

• Surface-treated (Delayed solubility): Used in dry mix applications

• Non-surface-treated: Instantly dissolves in cold water

Chapter 4: The Manufacturing Process of HPMC

4.1 Raw Material Selection

Cellulose extracted from wood pulp or cotton linters forms the base. Only high-purity cellulose ensures quality output.

4.2 Alkalization

The cellulose is treated with a sodium hydroxide solution, forming alkali cellulose, which is more reactive.

4.3 Etherification

This step involves the reaction with methyl chloride and propylene oxide. The result is hydroxypropyl methylcellulose ether.

4.4 Washing and Neutralization

The product is washed to remove residual chemicals and salts. Neutralization ensures the final product is non-toxic and meets purity standards.

4.5 Drying and Milling

The final HPMC product is dried and ground into a fine powder, ensuring consistency and flowability.
