HPS Hydroxypropyl starch ether

Hydroxypropyl starch ether (HPS) is a natural plant-based material.
It is a white fine powder obtained by modification, highly etherification reaction, and then spray drying, without plasticizer. It is completely different from ordinary starch or modified starch.


★ Good fast thickening ability; some water retention proprety.
★ The dosage is small.The extremely low addition amount will achieve a high effect.
★ Improve the material's resistance to attenuation.
★ Improve the material's operability and make the operation smoother.
★ Extend the opening time of the material.
 

It can be used as admixture for cement-based products, gypsum-based products and grey calcium products. It has good compatibility with other building additives. It can be used in combination with hydroxypropyl methyl cellulose (HPMC).It can play a thickening role, promote internal structure, have better crack resistance and improve ease. The addition of modified starch ether can significantly reduce the amount of HPMC added.


Feature:
Recommended dosage: 0.05% -0.1% can reduce methyl cellulose ether by about 0.1%.
