Hydroxypropylmethylcellulose (HPMC) is a versatile additive used in a wide range of building products. It has unique properties that make it an ideal component of self-leveling composite mortars, ensuring that the mixture is easy to apply, adheres well to the surface and dries smoothly.
Self-leveling composite mortar is becoming increasingly popular in the construction industry, primarily due to its ease of use and ability to provide a smooth, even surface. The addition of HPMC to such mortars enhances their properties, making them more effective and efficient.
One of the most significant advantages of HPMC is its ability to provide excellent water retention properties. When added to self-leveling composite mortar, it helps retain moisture in the mix longer. This is an important feature as it ensures that the composite mortar does not dry too quickly, allowing the contractor enough time to spread and level.
The water-retaining properties of HPMC help prevent the formation of cracks and fissures in composite mortars. This is vital to ensure that your self-leveling composite screed lasts as long as possible, minimizing the need for repairs or replacements.
HPMC also acts as a thickener to give the composite mortar the proper consistency. This ensures that the self-leveling composite mortar is easier to use and handle, making it ideal for construction projects where precision and accuracy are crucial.
The ability of HPMC to improve the bonding properties of composite mortars ensures good bonding to different surfaces. This is essential to ensure that the self-leveling composite mortar is strong and durable, providing a stable foundation for any structure built upon it.
HPMC also improves the sag resistance of self-leveling composite mortar, making it less likely to flow or drip when applied on vertical surfaces. This is essential to ensure that the composite mortar is applied evenly and consistently, providing a smooth, even surface.
HPMC is also non-toxic and has no harmful effects on the environment, making it a sustainable environmentally friendly additive. It is biodegradable and leaves no residue after use.
Hydroxypropyl methylcellulose (HPMC) is an excellent self-leveling composite mortar additive. Its unique properties significantly improve the water retention, adhesion and workability of composite mortar. Additionally, it is non-toxic and environmentally friendly, making it the additive of choice in the construction industry. By using HPMC regularly, contractors can achieve smooth, durable and high-quality finishes on their construction projects.

Hydroxypropyl methylcellulose, commonly known as HPMC, is a versatile polymer used in a wide range of industries. Its unique properties make it a valuable ingredient in a variety of applications, including building materials, pharmaceuticals, food, cosmetics, and more.
Uses of hydroxypropyl methylcellulose
construction industry
One of the most important uses of HPMC is in the construction industry, where it is used as a caulking agent. HPMC is used in grouts, tile adhesives, varnishes and self-leveling compounds to improve water retention, workability and adhesion. Adding HPMC to cementitious materials increases bond strength and prevents the mixture from cracking. It helps control the consistency and thixotropy of the mix, improves workability, reduces shrinkage, and enhances water retention during curing.
drug
HPMC is widely used in pharmaceutical preparations, especially tablet coatings and sustained-release preparations. It is used as a binder, emulsifier, disintegrant and thickening agent in pharmaceutical compounds. HPMC is used in topical ointments, gels, and creams to increase viscosity, enhance skin penetration, and ensure proper distribution of the drug.
Food and cosmetics
HPMC is a common ingredient in food and cosmetics. Used as thickener, emulsifier and stabilizer in food. HPMC is commonly used in ice cream, processed fruits and baked goods. In cosmetics, it is used as a thickener, emulsifier and suspending agent in creams, lotions and shampoos.
Factors affecting the price of hydroxypropyl methylcellulose
Hydroxypropyl methylcellulose type
There are several HPMC types on the market, each with its own unique properties. For example, low-viscosity HPMC is more soluble in water and dissolves quickly, making it ideal for immediate-release drugs. At the same time, high-viscosity HPMC has a slow dissolution rate and is suitable for sustained-release preparations. The type of HPMC used will affect its pricing.
Purity and concentration
The purity and concentration of HPMC also affect its price. Purer HPMC is more expensive due to the additional processing required to obtain pure HPMC. Likewise, higher concentrations of HPMC will also affect its price since more raw materials are required to produce it.
Source of raw materials
The source of raw materials used to manufacture HPMC also affects its price. HPMC is typically derived from wood pulp or cotton linters, the latter being more expensive. The location and quality of the raw materials used will affect the price of the final product.
Market demand
Market demand is another factor affecting HPMC prices. If the demand for HPMC is high, the price will increase and vice versa. The ongoing COVID-19 pandemic has led to increased demand for HPMC in the pharmaceutical industry as HPMC is used in the production of drugs such as remdesivir.
In summary
Hydroxypropyl methylcellulose is a versatile compound used in a variety of industries. Its unique properties make it an excellent ingredient in building materials, pharmaceuticals, food and cosmetics. The pricing of HPMC is affected by factors such as the type, purity and concentration of HPMC, source of raw materials, market demand and other factors. Although there are several factors that influence its pricing, HPMC remains a valuable polymer with a variety of uses and benefits.
