Starch ether is also called hydroxypropyl starch ether or HPS. It is produced by chemical and physical reactions using starch as raw material. A non-toxic, odorless white or beige powder dissolves in cold water to form a transparent or translucent viscous liquid.
Starch ether is typically combined with cellulose ether for optimal performance. Due to its compatible nature with other additives.
Starch Ether Uses - To Make Construction Easier
Starch ether has good compatibility with other construction additives. Such as HPMC, HEMC, HEC these cellulose ethers, redispersible polymer powder, PCE superplasticizer and retarders, etc.
WOTAIchem hydroxypropyl starch ether is an excellent thickener and water-retaining agent. A small dose can effectively improve slip resistance and workability and extend the opening time of the materials.
Strong anti-sagging effect. Keep the tiles very stable on a vertical wal. Allow a longer open time to maintain a viscous state.
Starch ether has a fast thickening effect on mortars. It can improve the rheological property of spraying or plastering mortars.
Starch ether has a unique chemical structure. The HPS can effectively prevent the thick mortar layer of flow hanging phenomenon.
WOTAIchem Commitment for Your HPS Powder
Hydroxypropyl Starch Ether in Construction
Hydroxypropyl starch ether can impart cement and gypsum based product properties. HPS powder has a similar chemical structure to HPMC.
On top of that, it has good compatibility with other building additives. When combined with cellulose ether, starch ether showing better thickening effects, crack resistance and good workability. Adding starch ethers can reduce the usage of mortar formulations.


Superior Starch Ether Solutions with R&D Strength
WOTAIchem is highly experienced in starch ether product research and development. We strive to stay at the forefront of the industry by continually upgrading and improving. We ensure that each type meets a consistent standard of excellence and quality.
Whether you need starch ether for dry mortar, tile adhesive, or putty and skim coat. We have all your requests covered! Choose WOTAIchem for easy construction steps and achieve wonderful results with tests of time!
Perfect Combination: Starch Ether and Cellulose Ether Makes Sense
Lubrication Enhanced
Cellulose ether provides the required viscosity of the construction materials, but it may increase application resistance. At this time, adding a small dose of starch ether can improve lubrication and help deliver a smoothest coating process.
Anti-Sag Performance Enhanced
Cellulose ether prevents sagging by increasing viscosity, while starch ether, a more effective anti sag additive, makes the materials more stable without flow or fall on vertical surfaces.
Cost Reduced
A small amount of starch ether can reduce the dosage of cellulose ether, while maintaing excellent overall performance.


OEM Starch Ether Powder
WOTAIchem modifies the HPS core indicators to achieve specific effects based on your requirements for retarding, anti-sliding and lubrication.
Our starch ether for construction can be customized with different viscosity ranges. Via establishing joint laboratories with universities, we have mastered the core technology of composite modification of the starch ether.
Customized solutions can be delivered to meet diverse formulation requirements in various areas.

The optimal dosage of HPS in construction materials varies based on the specific application and formulation. Generally, it falls within the range of 0.1% to 1.0% by weight of the total mixture. Adjusting the dosage according to the project requirements ensures the best performance and desired properties in the final materials.
If you have further questions, please feel free to contact the WOTAIchem team.
Hydroxypropyl starch ether is a cost-saving material and easy to obtain the desired thickening. In wet mortars, it has non-sagging, non-slip properties, good workability and low viscosity.
HPS can effectively prevent the stratification and settlement of mortar. It has a fast thickening effect on mortars. It can improve the rheological property of spraying mortar and plastering mortar.
We provide packing invoices, commercial invoices, order confirmation/receipts.
Because of the unique chemical structure of starch ether, it can effectively prevent the thick mortar layer of flow hanging phenomenon. The tile sliding, a thick layer of flow hanging phenomenon, has a good effect on the improvement. Adding a certain amount of hydroxypropyl starch ether to the mortar can delay its opening time. The water retention of starch ether can remain stable with the temperature increase. Therefore, the product can improve the water retention performance of mortar and make up for the rapid loss of water retention capacity of ordinary water retention agents with the increase in temperature.
