Product Description

Product Description

1. Brief Introduction
Hydroxypropyl Starch ether(HPS) is etherified starch, which is a starch substituent ether generated by the reaction between hydroxyl groups in starch molecules and reactive substances. Including hydroxyalkyl starch, carboxymethyl starch, cationic starch, etc. Due to the etherification of starch, the viscosity stability is improved, and the ether bond is not easily hydrolyzed under strong alkaline conditions. Therefore, etherified starch is used in many fields.

3.Applications
1. Food industry: Hydroxypropyl starch can be used as thickener, suspending agent, and adhesive.
2. Papermaking industry: Hydroxypropyl starch is used for internal sizing and surface sizing of paper to make the film smooth and reduce ink consumption.
3. Textile industry: Hydroxypropyl starch can be used as warp slurry to improve the wear resistance and weaving efficiency during weaving. Hydroxypropyl starch with a high degree of substitution can be used as printing paste.
5. Oil drilling industry: Stabilize well walls, improve drilling conditions, prevent collapse, flocculate drilling cuttings, etc.
6. Daily chemical industry: Hydroxypropyl starch is used as adhesive, suspending agent and thickener in daily chemical industry, cosmetics or coatings.
7. In building materials: Hydroxypropyl starch can be used as an adhesive, coating or gelling agent for organic liquids in building materials.
Various types of (cement, gypsum, gray calcium based) interior and exterior wall putty additives.
Various types of facing mortar and plastering mortar additives.
As a molding adhesive in various types of plaster, ceramics and porcelain products.
It has good thickening and stability, and plays the role of suspension and emulsification in aqueous solution.

 Advantages and applications:
1.Provides very good rapid thickening ability.
2.Excellent dispersibility.
3.Has a certain degree of water retention
4.Medium viscosity, high water retention
5.The dosage is small, and a very low increase can achieve high results.
6. Improve the overall anti-sag ability of the material and effectively prevent the hanging phenomenon of thick layers of mortar
7.It has good lubricity, which can improve the handling skills of materials and make the operation smoother.
8.The opening time of materials can be extended
9.It can improve the rheology of spray mortar, plastering mortar, etc.
10.It has good compatibility with other building admixtures. Used in conjunction with hydroxypropyl methylcellulose ether (HPMC), it can have a thickening effect. Promotes internal structure, has better crack resistance and improves workability. The amount of HPMC added can be significantly reduced by adding hydroxypropyl starch ether.
