Hypromellose eye drops
Hypromellose eye drops Hydroxypropyl methylcellulose (HPMC) is commonly used in the formulation of eye drops due to its ability to act as a thickener and lubricant. Eye drops containing HPMC are often used to relieve dry eyes and provide temporary relief from irritation and discomfort. The mechan...Read more -
What type of polymer is HPMC?
What type of polymer is HPMC? HPMC, or hydroxypropyl methylcellulose, is a type of cellulose-based polymer that is widely used in the pharmaceutical, food, and personal care industries. Cellulose is a natural polymer that is found in plants and is the most abundant organic compound on earth. It i...Read more -
Is HPMC a surfactant?
Is HPMC a surfactant? HPMC, or Hydroxypropyl Methylcellulose, is not a surfactant in the strictest sense of the term. Surfactants are molecules that have both hydrophilic (water-loving) and hydrophobic (water-repelling) ends, and they are used to reduce the surface tension between two immiscible...Read more -
The role of redispersible latex powder in dry-mixed mortar
The affinity of latex powder to water when it is redispersed, the different viscosities of latex powder after dispersion, the influence on the air content of mortar and the distribution of air bubbles, the interaction between rubber powder and other additives, etc., make different latex powders h...Read more -
Effect of latex powder on the strength of cement-based floor materials
In terms of flexural and compressive strength, under the condition of constant water-cement ratio and air content, the amount of latex powder has a strong influence on the flexural and compressive strength of cement-based floor materials. With the increase of latex powder content, the compressive...Read more -
The effect of the change of latex powder content on the properties of polymer mortar
The change of latex powder content has obvious influence on the flexural strength of polymer mortar. When the content of latex powder is 3%, 6% and 10%, the flexural strength of fly ash-metakaolin geopolymer mortar can be increased by 1.8, 1.9 and 2.9 times respectively. The ability of fly ash-me...Read more -

The effect of adding latex powder to cement/gypsum-based dry powder ready-mixed mortar
Redispersible latex powder has good redispersibility, redisperses into emulsion when in contact with water, and its chemical properties are almost identical to the initial emulsion. Adding dispersible emulsion latex powder to cement or gypsum-based dry powder ready-mixed mortar can improve variou...Read more -
The role of adding latex powder in tile adhesive
Different dry powder mortar products have different performance requirements for redispersible latex powder. Because ceramic tiles have good decorative and functional features such as durability, waterproof and easy cleaning, their applications are very common; tile adhesives are cement-based bon...Read more -
Hydroxyethylcellulose gel
Hydroxyethylcellulose (HEC) is a water-soluble polymer commonly used in the formulation of gels due to its thickening, stabilizing, and gelling properties. HEC gels are used in a variety of applications, including personal care products, pharmaceuticals, and food. To create a HEC gel, the polymer...Read more -
Hydroxyethylcellulose vs carbomer
Hydroxyethylcellulose vs carbomer Hydroxyethylcellulose (HEC) and carbomer are two commonly used polymers in the personal care industry. They have different chemical structures and properties, which make them suitable for different applications. HEC is a natural, water-soluble polymer derived fro...Read more -
How long does it take HEC to hydrate?
How long does it take HEC to hydrate? The time it takes for hydroxyethyl cellulose (HEC) to hydrate depends on several factors, such as the specific grade of HEC, the temperature of the water, the concentration of the HEC, and the mixing conditions. HEC is a water-soluble polymer that requires hy...Read more
