Hydroxypropyl starch ether is a white to yellow powder, odorless, tasteless, melting point at about 371 ° , PH 7-9, humidity should be kept in ≤1% . Hydroxypropyl starch ether as a thickening agent is suitable for cement-based, lime-calcium-based, neutral and alkaline gypsum-based products

Hydroxypropyl starch ether is packaged in paper and plastic bags lined with polyethylene plastic bags. In storage, hydroxypropyl starch ether should be stored in a cool and dry place to avoid moisture absorption and caking, store in an airtight bag and keep in a dry environment. Each bag weighs 25KG. Care should be taken during transportation to avoid breakage.

Hydroxypropyl starch ether can be widely used in combination with building materials because of its unique characteristics: first, it has good rapid thickening ability and a certain degree of water retention, the second is to improve the anti-skid ability of the material, increase the viscosity between the materials. The third is to prolong the use of the material, increase the use rate, reduce the cost and finally improve the operation and construction performance of the material, make the operation more smooth, fast

Hydroxypropyl starch ether is mainly used in various (cement, gypsum, lime-calcium base) putty inside and outside the wall, so that the operation is more smooth. Starch ether can improve the adhesion of ceramic tile. It can also improve the fluidity of various mortars. Hydroxypropyl starch ether is commonly used in combination with Methyl cellulose ether, and Methyl cellulose can be added to a mortar to improve the viscosity of the mortar, resulting in smoother use.
