Dispersible polymer powder

1.Product introduction Name: VAE dispersible latex powder Packing: 25kg/bag The redispersible latex powder product is a water-soluble white or off-white flowable powder, which is a copolymer of ethylene and vinyl acetate, and uses polyvinyl alcohol as a protective colloid. Due to the high binding... Read More

Basic knowledge of dispersible polymer powder

1. basic concept Redispersible polymer powder is the main additive for dry powder ready-mixed mortar such as cement-based or gypsum-based. Redispersible latex powder is a polymer emulsion that is spray-dried and aggregated from the initial 2um to form spherical particles of 80~120um. Because the ... Read More

Hydroxypropyl methylcellulose HPMC

Hydroxypropyl methyl cellulose, also known as hypromellose, cellulose hydroxypropyl methyl ether, is obtained by selecting highly pure cotton cellulose as raw material and specially etherified under alkaline conditions. Widely used in construction, chemical, pharmaceutical and other industries. c... Read More

What factors affect the water retention of hydroxypropyl methylcellulose

The higher the viscosity of hydroxypropyl methylcellulose, the better the water retention performance. Viscosity is an important parameter of HPMC performance. At present, different HPMC manufacturers use different methods and instruments to measure the viscosity of HPMC. The main methods are Haa... Read More

Popularization of hydroxypropyl methylcellulose HPMC knowledge

Hydroxypropyl methylcellulose HPMC is a non-ionic cellulose ether made from natural polymer material cellulose through a series of chemical processing. They are an odorless, tasteless and nontoxic white powder that swells in cold water to a clear or slightly hazy colloidal solution. It has the pr... Read More

Relationship between Viscosity and Temperature of Hydroxypropyl Methylcellulose (HPMC)

(1) Determination of HPMC viscosity: The dried product is prepared into an aqueous solution with a weight concentration of 2 °C, and is measured by an NDJ-1 type rotational viscometer; (2) The appearance of the product is powder, and the instant product is suffixed with “s” in the bra... Read More

Hydroxypropyl methyl cellulose in machine spray mortar

With the wide use of mortar, the quality and stability of mortar can be well guaranteed. However, since the dry-mixed mortar is directly processed and produced by the factory, the price will be higher in terms of raw materials. If we continue to use manual plastering on site, it will not be compe... Read More
