Dispersible polymer powder is physically mixed with other inorganic binders(such as cement, slaked lime, gypsum, clay, etc) and various aggregates, fillers and other additives such as Hydroxypropyl Methylcellulose(HPMC), polysaccharide(starch ether) and cellulose, finally to produce mortar. When the dry mortar is added to the water and stirred, the rubber powder particles are dispersed into the […]

Vinyl acetate and ethylene are copolymerized in an emulsion process to first produce VAE compositions containing between 10 and 40 percent ethylene in the copolymer.  Ethylene is a soft, hydrophobic monomer unit in the copolymers, functioning as an internal “plasticizing” moiety. In copolymers, ethylene effectively reduces the glass transition temperature (Tg) of the hard, polar […]

Cement is a fundamental building material used in construction projects around the world. It is made up of several components, including water, aggregates, and Portland cement. However, these components alone may not be enough to achieve the desired properties, such as workability, strength, and durability, that are necessary for construction applications. Therefore, additives are commonly […]

Water Retention Cellulose has excellent water retention properties, which can be beneficial for cement-based putty. Improved water retention means that the putty dries more slowly, reducing the likelihood of cracks forming as it sets. This property also ensures that the cement hydrates more effectively, leading to a stronger bond. Constructability Cellulose fibers can increase the […]

Gypsum is another area where HPMC truly shines. HPMC for gypsum has become a must-have for producing high-performance drywall compounds, plaster, and other gypsum-based products.And, why is it so essential? Firstly, HPMC is a water retention agent in gypsum-based products, which is crucial during the mixing and application process. By retaining moisture, HPMC ensures that the gypsum mixture doesn’t dry too quickly, giving workers more time to […]

If you’ve ever applied wall putty or tile adhesive, you’ve probably encountered HPMC without even knowing it. This powerful ingredient is a game-changer when it comes to improving the workability and adhesion of construction materials. For wall putty, HPMC acts as a thickening agent, ensuring that the paste is easy to spread while maintaining the right consistency. It helps retain water in the mixture, making it easier […]

Applications of Redispersible Polymer Powder (RDP) 1. Construction industry: Tile Adhesives: RDP enhances the adhesion, flexibility and water resistance of tile adhesives, improving the overall performance and durability of your tile installation. Cement Mortar: RDP is often used in cement based mortars to improve workability, adhesion and durability. It also reduces cracks and increases the […]

1. Supplier Verification: The first step in ensuring RDP quality and authenticity is to establish trust in your supplier. Research and choose reputable manufacturers or distributors known for producing high-quality RDP. Look for certifications and industry affiliations, which can be indicative of a commitment to quality. 2. Material Data Sheets (MDS): Request Material Data Sheets […]

The viscosity of HPMC is an important factor in its price. Generally speaking, the higher the viscosity of HPMC, the higher its price. This is because higher viscosity HPMCs require higher process requirements and more complex production processes, resulting in higher costs. For example, 400 viscosity HPMC is usually used in gypsum self-levelling products, but its price […]
