HPMC

Hydroxypropyl methylcellulose is a non-ionic water-soluble cellulose ether, which is made from plant fiber or natural polymer fiber through a series of chemical processes. It is odorless, tasteless, non-toxic white powder, soluble in cold water but insoluble in warm water, slowly swells and peptizes in warm water, forms a viscous colloidal solution, and cools into a solution. According to different production specifications, it can be used in different application scenarios, as thickeners, dispersants, adhesives, excipients, oil-resistant coatings, fillers, emulsifiers and stabilizers.

Product Specification

HPMC can be used in various industries such as construction, food, medicine, PVC, personal care, etc., as follows:

Ⅰ、HPMC for construction 

As HPMC for construction, it can be used as thickener, protective colloid, stabilizer, suspending agent and water retention agent in construction applications. It can be used as an additive for plaster, putty, mortar, tile adhesive and other construction scenes; The architectural grade HPMC we produce has the following characteristics:

• stable stomata

• Specific consistency changes for easy handling

• Improve substrate adhesion of building materials

• Selective control of rheology for improved processability

• Short time to develop temperature stable high water retention capacity Low addition rate in formulation

Ⅱ、HPMC for food

A semi-synthetic, inactive, viscoelastic polymer used as a component or excipient of food additives, commonly found in various commodities, as a food additive can play the following roles: emulsifier, thickener, suspending agent and substitutes for animal gelatin. The advantages of our food grade HPMC:

• Has excellent enzyme resistance and emulsion stability.

• Reduces oil content and improves the taste, appearance, texture, moisture and air content of foods lost due to oil reduction.

• Has excellent processability and thickening properties.

• It can effectively control the moisture content of food from freezing to normal temperature, and reduce the damage, ice crystals and texture deterioration of food caused by refrigeration.

Ⅲ、HPMC for PVC

HPMC is one of the main dispersants in the PVC industry, which can control the characteristics of the polymer during processing and the characteristics of the final product. In the suspension polymerization system, it plays a dual role of dispersion and stability protection. In the process of vinyl chloride suspension polymerization, the interfacial tension between vinyl chloride monomer (VCM) and water is reduced, which is conducive to the uniform and stable dispersion of VCM in the aqueous medium; to prevent the coalescence of VCM droplets in the early stage of polymerization; Coalescence between particles.

Ⅳ、HPMC for ceramics

In the production of thin-walled honeycomb ceramics, HPMC has obvious influence on the shape retention of the green body. After adding HPMC, the operability of the honeycomb ceramic mold can be improved, the strength of the honeycomb ceramic product body can be improved, and the honeycomb ceramic product is smooth and fine; due to the good lubricity of HPMC, it is beneficial to the extrusion molding of the honeycomb ceramic, ensuring the dimensional accuracy of the product, Ensure the uniformity of wall thickness, reduce the scrap rate, and improve the product qualification rate.

Ⅴ、HPMC for medicine

Since HPMC turns into gel when heated, high-grade HPMC can be used in pharmaceutical excipients, such as thickeners, dispersants, emulsifiers, and film-forming agents.

Our medical grade HPMC is used in film coatings and binders to significantly improve drug stability and dissolution, and enhance tablet water resistance. It can also be used as a suspending agent in suspension, as a matrix material in ophthalmic preparations, as a matrix material in hydrophilic gel matrix sustained-release tablets and intragastric floating tablets. Our medical grade HPMC indicators comply with the US Pharmacopoeia, European Pharmacopoeia and Chinese Pharmacopoeia.

Ⅵ、HPMC for self-leveling

HPMC has an important influence on the water retention, consistency and workability of self-leveling mortar. An appropriate amount of HPMC can keep the moisture in the mortar for a long time. It has a certain retarding effect on mortar. With the increase of cellulose ether content, the setting time of mortar will be prolonged. It can enhance the plasticity and flexibility of mortar, reduce the stiffness of the transition zone between mortar and substrate, reduce the sliding ability between interfaces, and enhance the bonding effect of mortar and substrate to a certain extent.

Ⅶ、HPMC for Personal Care

HPMC is odorless, tasteless and non-toxic, and can be dissolved in cold water and organic mixed solvents to form a transparent viscous solution. It has surface activity, high transparency, strong stability, soluble in water and not affected by pH value, and effectively improves the fluidity of the system. It has thickening and antifreeze effects in shampoos and shower gels, has water retention and good film-forming properties for hair and skin, and improves skin feel. In cosmetics, it plays the roles of thickening, foaming, stable emulsification, dispersion, adhesion, film formation, and water retention.
