Starch Ether Supplier,Starch Ether Wholesaler
Hydroxypropyl starch ether can give unique properties to cement and gypsum based products. It has a similar chemical structure to Hydroxypropyl Methyl Cellulose (HPMC), and not only has the function of Hydroxypropyl Methyl Cellulose (HPMC), but also has good compatibility with other building additives. Hydroxypropyl starch ether and Hydroxypropyl Methyl Cellulose (HPMC) can be used together to provide better thickening effect, better crack resistance, and improved ease of use. And by adding starch ether, the cost of mortar formulation can be significantly reduced.
The performance of starch ether in dry mortar is as follows
Due to the special chemical structure of starch ether, hydroxypropyl starch ether can effectively prevent the phenomenon of mortar thick layer hanging, and it has a good improvement effect on the bad phenomenon of tile sliding and thick layer hanging;
Adding appropriate amount of hydroxypropyl starch ether in mortar can delay the opening time of mortar. The water retention of starch ether can remain stable with the increase of temperature. Therefore, this product can not only improve the water retention performance of mortar, but also compensate the phenomenon that the water retention capacity of common water retention agent retains rapidly with the increase of temperature;
Hydroxypropyl starch ether has fast thickening function for mortar, which can improve the rheology of spraying mortar and plastering mortar;
Hydroxypropyl starch ether can effectively prevent the delamination/separation of mortar, and can be well used in self-leveling mortar;
Hydroxypropyl starch ether is added in the following materials:
All kinds of internal and external wall putty powder (cement, gypsum-based);
All kinds of (tile, stone) adhesives;
All kinds of finishing mortars, plastering mortars, especially exterior wall insulation mortars.

Hydroxypropyl Starch are a starch-based additive designed for dry mortars in the building industry. These starch ethers can improve the performance and optimize the workability of dry mortar by modifying the thickness and rheology of varied dry mortars based on cement and gypsum.� Starch� ether� should be used in combination with cellulose derivatives. It can well perform in neutral and alkaline conditions, and it is compatible with other additives in gypsum or cement-based building materials.
Starches can be modified in several ways to change their function as additives in products. They can be cross-linked, where the chains get stuck together into a mesh. They can be heated to break the long chainsdown into simpler molecules like dextrin, polydextrin and malto-dextrin. These are simply short starches. Modified starch mainly includes absorbent starch, etherized starch, cross-linked starch, oxidized starch and phosphate ester starch. It is a free flowing powder free from lumps, white and off white in color. Applications: * It provides a homogeneous solution and very good dispersion effect & no sedimentation even after prolonged time of storage. * It has better adhesion effect and quick drying characteristics. * It has very good film forming characteristic for smooth and uninterrupted operation. * No shrinkage and no peel off so paper manufacturers can overrule common problem of poor quality tube pasting powder. * It is also widely used in food, pharma, textiles, paper box industries, tube industries, file industries, paper drum industries book binding industries, dyes industries, foundry industries, fireworks industries, etc.
SODIUM CARBOXYMETHYL STARCH (CMS or SCMS) is a starch ether derivative derived from starch. It is soluble in water at room temperature and forms a transparent to light milky and viscous solution. CMS is an important modified starch with unique properties due to the presence of negatively charged functional group (CH2COO-). The introduction of carboxymethyl groups interrupts the ordered structure of native starch and intervenes with the re-association of gelatinized starch. This modification yields starch with decreased gelatinization temperature, increased solubility and improved storage stability. CMS is chemically processed carbohydrate typically derived from Native starch viz. Maize, Potato, Tapioca & Rice. These Sodium Carboxymethyl starch and solution are alkaline in nature and have the capacity to replace sodium carboxymethyl cellulose in fields like textile sizing & printing, corrugated paper, paper sizing, oil well drilling, water based distemper, oil bound distemper, electrodes, ceramics, pesticides, foundry, adhesives and others. The chemical name of SCMS is SODIUM SALT OF CARBOXYMETHYL ETHER OF STARCH
Product Description Construction grade hydroxypropyl starch is the fastest growing industry in starch ether application industry. ZHUOJUN ZJ-HPS is a kind of ionic hydroxypropyl starch, which is produced by a series of chemical and physical reactions with starch as raw material. It is non-toxic, tasteless white or beige power, which can be dissolved in cold water to form transparent or translucent viscous liquid. It is effective in thickening, adhesion, dispersion, emulsification, suspension, adsorption, surface activity, water retention and so on. And it is well compatible with other additives in gypsum or cement based building materials. ZHUOJUN ZJ-HPS can be applied in following construction materials: - Cement and gypsum based mortars - Tile adhesives - Joint filler and crack filler ZHUOJUN ZJ-HPS Advantages: Improve the performance and workability of dry mortar Improve adhesion strength Excellent performance in neutral and alkaline conditions Good solubility in cold water with stable transparent and colorless solution Well compatible with other additives Cost-effectiveness Technical Data for ZJ-HPS Model No.ZJ-HPS Appearancewhite or beige power Particle Size (%, 100 mesh passing rate)98.5% SolubilitySoluble in cold water Water Content (%)â?¤14 Hydroxypropyl Content (%)20-40 pH Value (1% aqueous solution at 25) 5-11.5 Viscosity (mPa's, 5% aqueous solution at 20) 100 Packaging A.Standard packed in 25 KG per paper plastic composite bag B.Big bags or other special packages are possible on request Storage Stored in its original packaging in dry place Warranty It is recommended to use ZHUOJUN HPS within 12 months.
