Hydroxypropyl Starch Ether

Hydroxypropyl Starch Ether

Hydroxypropyl Starch Ether (HPS) is the general term for a class of modified starches containing ether bonds in the molecule. It is also called etherified starch. HPS is mainly used in the mortar of construction, It can affect the consistency of mortar based on gypsum, cement and lime to improve the workability and sag resistance of mortar.Starch ether usually Used in conjunction with unmodified and modified cellulose ethers.

Matecel ® HPS Features：

Matecel® HPS is usually used in conjunction with methyl cellulose ether. Adding an appropriate amount of HPS to methyl cellulose ether can significantly improve the sag resistance and slip resistance of the mortar.

Adding an appropriate amount of Matecel® HPS in the mortar which containing methyl cellulose ether can obviously increases viscosity of the mortar, improve the flow performance, and make the construction smoother.

Increasing the water retention of the mortar and extend the open time.

Matecel® HPS Low in the amount used, with an extremely low addition amount to achieve very high effects， reduce the costing of mortar.

Grade Viscosity (mPa.s, 5% solution)
HPS350 3,000-5,000
HPS680 6,000-8,000
