Hydroxypropyl Starch Ether
Good rapid thickening ability,Medium viscosity, with certain water retention properties
Low dosage
Good plasticity effect and excellent anti sagging performance
Good lubricity, improving material workability
Hydroxypropyl starch ether(HPS) is nonionic and has high stability of substituting ether bond. In the process of hydrolysis,oxidation, dextrinizing and cross-linking reaction, ether bond cannot be broken and it can replace the group and does not fall off.
It is a kind of chemical modified starch ether, which is mainly used as thickener and texturing agent for cement or gypsum based mortar products.
HPS is a cost-saving material and is easy to obtain the required thickening effect. During the application of wet mortars,it gives non-sag, anti-slip properties and good workability and low stickiness.
Hydroxypropyl Starch Ether can impart unique properties to cement and gypsum based products. It has the similar chemical structure with Hydroxypropyl Methylcellulose(HPMC) that not only provide Hydroxypropyl Methylcellulose(HPMC)-like function, but also has good compatibility with other building additives. In combination with Hydroxypropyl Methylcellulose(HPMC), Hydroxypropyl Starch Ether can play a better thickening effect, with better crack resistance and improve workability. And by adding starch ether, the cost of the mortar formulation can be significantly reduced.
