Brief Introduction
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.
Starch Ether Properties
1. Improve sag resistance & anti-slap
2. Optimize rheological behaviour, particularly the flow characteristics and workability
3. Enhance adhesion strength
4. Increase mortar yield
5. Cost-effective. Obtain desired thickening effect with very low dosage

We provide customers with the following services:
• Help customers find matching products quickly.
• Customized production based on samples provided by customers.
• Suggestions for formula improvement. We can help customers provide suggestions for improving formulations based on
local climate conditions, building material properties and construction habits to improve product performance and control costs.
We have chemical lab and application lab to ensure the best satisfaction for each order.
• Chemical lab can help us evaluate product properties such as viscosity, humidity, ash content, PH value, methyl and hydroxy
-propyl content, substitution degree, etc.
• Application lab can help us measure open time, water retention, adhesive strength, slip resistance and sag resistance,
setting time, workability, etc.
