Product Description

Product Introduction

 

• Basic Information: HPMC, short for Hydroxypropyl Methyl Cellulose, is also known as Cellulose Hydroxypropyl Methyl Ether. It is an important non - ionic cellulose ether. It appears as a white or off - white powder, with a particle size where the pass rate through 100 - mesh is greater than 98.5% and that through 80 - mesh is 100%. Its apparent density is 0.25 - 0.70 g/cm³ (usually around 0.5 g/cm³), and its specific gravity is 1.26 - 1.31.
• Other Properties: It has high transparency and stable performance. Different specifications of products have different gel temperatures. It also has thickening ability, low salt resistance, pH stability, water - retention property, dimensional stability, excellent film - forming property, and extensive enzyme resistance, dispersibility, and adhesiveness.

Product Application

• Construction Materials: In cement - based and gypsum - based building materials, it is widely used to improve the processing performance of materials and the performance of final products. In dry - mix mortar, it can improve the water - retention property of mortar, prolong its open time, and improve construction performance. In tile adhesives, it can increase the bonding strength, prevent sagging, and improve the construction effect. In addition, it is also used in products such as gypsum boards, putty powders, and self - leveling mortars to play multiple roles such as thickening, water - retention, and lubrication.
• Pharmaceuticals: As a pharmaceutical excipient, it has good safety and biocompatibility and is widely used in drug preparations such as tablets, capsules, and sustained - release preparations. In tablet production, it is commonly used as a binder, film - forming agent, and controlled - release agent, which can control the drug release rate and improve the stability and bioavailability of drugs. In addition, it is also used to produce plant - based capsule shells, which have the advantages of being vegetarian - friendly and allergen - free.
• Food: It is used as a food additive, mainly playing roles such as thickening, emulsifying, stabilizing, and film - forming. It is widely used in flour products, dairy products, frozen foods, and seasonings. For example, in flour products, it can improve the water - retention property and ductility of dough, and improve the taste and texture of food; in ice cream, it can prevent the formation of ice crystals and improve the taste and stability of the product; in seasonings, it can improve the viscosity and stability of the product and prolong the shelf life.
• Cosmetics and Personal Care Products: In skin - care products, shampoos, shower gels, and other products, it is mainly used as a thickener, emulsifier, and stabilizer, which can improve the texture and stability of products and improve the user experience. In addition, it is also used in toothpaste to play a role in thickening and moisturizing, improving the spreadability and cleaning effect of toothpaste.
• Coatings and Inks: As a thickener and stabilizer, it is widely used in water - based coatings and inks. It can improve the rheological properties and construction performance of coatings and inks, prevent the precipitation and delamination of pigments, and improve the uniformity and adhesion of coatings. In latex paint, it can improve the anti - sagging property and scrub resistance of the paint film and prolong the service life of the coating.
• Other Fields: In the electronic industry, it is used for thickening and film - forming of electronic pastes; in the paper - making industry, as an additive, it can improve the strength and smoothness of paper; in the textile industry, it is used for textile sizing and printing pastes, which can improve the hand feel and color brightness of textiles. In addition, it is also used in pesticide preparations, which can improve the adhesion and moisturizing property of pesticide spraying liquids, prolong the residence time of pesticides on the surface of plants, and thus improve the utilization efficiency and insect - killing effect of pesticides.
