Hydroxy propyl methyl cellulose (HPMC) is odorless, tasteless,non-toxic cellulose ethers produce from natural high molecula and protective colloid properties of surface activity and maintain moisture function properties ect.cellulose through series of chemical processing and achieved. HPMC is white powder with good water solubility. It has thickening, adhesion ,dispersing,emulsifying, film, suspended, adsorption, gel. In the course of construction,HPMC is […]

Hydroxypropyl Methyl Cellulose (HPMC) is the most commonly used additive in dry mortar. Cellulose ether plays a crucial role in dry mortar, where dissolved cellulose ether ensures the even distribution of cementitious materials in the system through its surfactant action. Acting as a protective colloid, cellulose ether ‘wraps’ solid particles, forming a lubricating film on their […]

Hydroxypropyl Methylcellulose (HPMC) is a type of cellulose ether used as a viscosity modifier, and its viscosity value has a significant impact on the performance and applications of products. This article will explore the meaning and application of HPMC viscosity values from various perspectives. The viscosity value of HPMC refers to the resistance to flow of an HPMC solution under certain […]

Glass indicator of the physical properties of redispersible polymer powders. For specific products, a careful selection of the glass transition temperature of redispersible polymer powder can help improve the flexibility of the product and prevent issues like cracking. Redispersibility. forming temperature is low. After the redispersible polymer powder is mixed and emulsified with water, it exhibits […]

Mix the redispersible polymer powder and water in a ratio of 1:5, stir evenly, let it sit for 5 minutes, and observe the sedimentation at the bottom. In general, the fewer deposits, the better the quality of the redispersible polymer powder. Mix redispersible polymer powder and water in a 1:2 ratio, stir thoroughly, allow it to […]

The redispersible latex powder product is a water-soluble redispersible powder, divided into copolymers such as ethylene/vinyl acetate, vinyl acetate/tertiary carbonate ethylene, and acrylic copolymers. It is a powder adhesive produced by spray drying, with polyvinyl alcohol serving as a protective colloid. This powder can quickly redisperse into an emulsion upon contact with water. Due to its high […]

In the dynamic world of construction materials, the quest for solutions that balance workability and durability is ever-present. One remarkable innovation that has garnered attention in recent years is the integration of HPMC for Gypsum. This powerful combination has a profound impact on both the workability during application and the overall durability of gypsum-based products. In […]

Redispersible polymer powder is a versatile and crucial component in the construction industry, especially in the formulation of mortar and cement products. Its use contributes to the enhancement of various properties, leading to high-quality and durable construction materials. Here are some key aspects of how redispersible polymer powder serves as a vital ingredient in mortar and […]

Choosing the right Hydroxypropyl Methylcellulose (HPMC) for cement-based putty applications is crucial, as different HPMC grades can have varying properties that directly impact the performance of the putty. Here are key considerations highlighting the importance of selecting the appropriate HPMC: Viscosity and Rheology: Different HPMC grades exhibit varying viscosity levels and rheological behaviors. The viscosity of HPMC influences the workability […]
