(RDP) MANUFACTURERSREDISPERSIBLE POLYMER POWDER is a free-flowing, white powder obtained by spray drying of an aqueous vinyl acetate-ethylene copolymer dispersion. Redispersible polymer powders are polymer emulsions which have been converted by spray drying (atomizing the aqueous polymer dispersions in a stream of hot air) to free flowing powders.

Hydroxypropyl Methyl Cellulose, also known as hypromellose and cellulose hydroxypropyl methyl ether, is made from highly purified cotton cellulose as a raw material and specifically etherified under alkaline conditions.

Regarding the hottest chemical products in life, first of all, it is necessary to pay more attention and attention to the most critical advantages and performances, so as to ensure the availability of this product more effectively. This is the case with propyl methyl cellulose products.

Hydroxypropyl Methyl Cellulose in dry powder mortar, the addition of cellulose ether is very low, but it can significantly improve the performance of wet mortar, which is the main additive that affects the construction performance. At present, the cellulose ether used in cellulose in dry powder mortar is mainly cellulose ether (HPMC).

The wet mix mortar is cement, fine aggregate, additives and water, and various components are determined according to the properties. After the mixing is measured at the mixing station according to a certain ratio, the mixture is transported to the place of use by a mixing truck and placed in a special container for storage, and the wet mixture is used within the specified time.

As a more commonly used additive in dry powder mortar, hydroxypropyl methylcellulose plays an important role in it. Due to its own structural characteristics, it can also ensure that the water in the mortar will not be lost. This is its water retention. As one of the basic indicators of this additive, it is also important to do its detection work before using it. So what methods can help us?

HPMC  advantages and application

As for hydroxypropyl methylcellulose, many people may not be clear about it, but it is very complicated from the name. Today I will come to help you understand this product from a few small questions. Please read it carefully.

Hydroxypropyl content and viscosity, most users are concerned about these two indicators. With high hydroxypropyl content, water retention is generally better. Large viscosity, water retention, relatively (but not absolute) is better, and high viscosity, better use in cement mortar.
