High Performance Pgs Pregelatinized Starch for Textile Sizing at Wholesale Price with Consistent Viscosity

Product Description

Pregelatinized Starch (Instant Starch)

Pregelatinized Starch is a physically modified starch produced by cooking, drying, and grinding native starch. It is a cold-water soluble powder that swells and thickens rapidly without the need for heating. This product is widely used as a binder, thickener, and disintegrant across various industries.

Key Features

Instant Solubility: Disperses and swells quickly in cold water.

High Gelatinization Degree: ≥ 98.5%, ensuring superior binding and thickening efficiency.

High Purity: Low ash and impurity content, ensuring stability in complex formulations.

Excellent Stability: Low moisture content prevents caking and extends shelf life.

FAQ

Q1. What is the difference between pregelatinized starch and regular starch?

A: Pregelatinized starch is physically modified through cooking, drying and grinding, allowing it to dissolve and swell in cold water without heating. Regular native starch requires cooking to gelatinize.

 

Q2. What is the typical gelatinization degree of your product?

A: Our pregelatinized starch has a gelatinization degree of ≥98.5% (tested per GB/T 38573-2020), far exceeding the industry standard requirement of >50%, ensuring superior binding and thickening efficiency.

 

Q3. What are the main applications in construction?

A: It is widely used as a binder and thickener in dry-mix mortar, tile adhesives, wall putty, gypsum plasters, and self-leveling compounds to improve workability, water retention, and crack resistance. 

 

Q4. Can it be used together with cellulose ethers (HPMC/CMC)?

A:Yes. Pregelatinized starch works synergistically with HPMC, CMC, and HEC in dry-mix mortar formulations. Together they provide a complete "cellulose + starch" binding and thickening solution for construction applications. 

 

Q5. What is the shelf life and packaging?

A: Shelf life is 24 months under proper storage (cool, dry, well-ventilated area). Standard packaging is 25kg kraft paper bags with inner PE liner; jumbo bags are also available upon request.
