Hydroxypropyl Methylcellulose :


As the water-retaining agent and retarder of cement mortar, it enables mortar to own pumping capability. In cement mortar, gypsum slurry, putty powder or other building materials, it can function as adhesives to enhance smearing capacity and prolong operable time. In ceramic tiles, marble and plastic decoration, hpmc can be used as pasting strength agent and reduce the cement content. Water retention capacity of hpmc helps to prevent the crazing of slurry resulting from drying quickly and to enhance the strength after hardening.

Polyanionic Cellulose (pac) :

Petroleum drilling, especially in salt well and offshore oil drilling.
In the shape of white to light yellow powder or particles, polyanionic cellulose is tasteless, nontoxic, strong in hygroscopicity, and freely soluble in cold and hot water.

Polyanionic cellulose polymer has excellent heat-resistant stability, salt tolerance and strong antibacterial activity. The slurry or fluid prepared from the product has better fluid loss reducing capability, rejection capability and higher temperature tolerance. Polyanionic cellulose is widely used in petroleum drilling, especially in salt well and offshore oil drilling.

We are Calcium Formate manufacturer and exporter in China. We are now promoting our calcium formate products in global market with very competitive price.

We can supply Calcium Formate for both feed grade and industrial grade. We can also produce the main raw material formic acid which is one of the most elements for calcium formate, so it's easy for us to control the quality and the costs, our quotation is very competitive.
For industrial grade, we use the way of naturally cooled crystal, so the particle and the shape are all well-proportioned.
For feed grade, we use high purity formic acid and feed grade calcium carbonate, so the purity of calcium formate is high and the calcium content is good with low heavy metal. And we use the same way of naturally cooled crystal as industrial grade.

Our product is made from high purity formic acid and calcium carbonate, suitable for both feed additive and industrial use. Here is our specification and price for your reference-

Hydroxypropyl methyl cellulose
Hs code:3912, 900
Cas:9004-65-3
Hydroxypropyl methyl cellulose is a kind of white or slightly yellowish powder, odorless, tasteless, and non-toxic. The product can be dissolved in cold water to form a transparent viscous solution. The aqueous solution of this product has surface activity so that it has emulsification, protective colloids and relative stability. Ph stability: the aqueous solution viscosity of this product is relatively stable in the range of ph 3.0â??11.0. As the product is non-ionic, and in the preparation process can be effectively purified by washing with hot water, it has a very low ash content. Hydroxypropyl methylcellulose products can fully meet the standards for use of medicine, food, construction and personal care products.

potassium sorbet granular, CAS 24634-61-5
we are a manufacturer of potassium sorbet granular
Potassium sorbate, also known as 2, 4-hexadienoate potassium, is the potassium salt of sorbate, the molecular formula is C6H7O2K, white to light yellow flake crystal, crystal particles or crystal powder, odorless or slightly smelly, easy to absorb moisture in the air for a long time, oxidative decomposition and discoloration. Soluble in water, propylene glycol and ethanol. It is often used as a preservative, destroying many enzyme systems by binding to the sulfhydryl groups of microbial enzyme systems. It is much less toxic than other preservatives and is now widely used.

Potassium sorbate is mainly used as a food preservative. It is widely used because of its strong inhibition of mold and spoilage bacteria, and it is easily dissolved in water. Potassium sorbate has been recommended by the Food and Agriculture Organization of the United Nations as a safe and efficient food preservative. Potassium sorbate has low toxicity, good mildew proof effect, does not change the original nature of food, easy to use, wide application range and other characteristics, so many foreign developed countries have taken potassium sorbate as a good, efficient preservative, a large number of applications in food. At present, potassium sorbate has been widely used in the domestic food industry. With the continuous breakthrough of production cost and production technology, potassium sorbate, as a low-toxicity, safe and efficient food preservative, will continue to expand its application scope
