Starch ether

0 Comment

Starch is one of the most prolific natural polymers, and is composed of amylose and amylopectin. Amylopectin molecules are much larger than amylase. Starch ethers are chemically modified from starch. Potato starch, which is of high-purity, is the preferred amylase for building. Starch molecular weight and the degree of etherification determine the consistency and workability.. read more →

HPS (short for hydroxypropyl starch ether) enables cement- and gypsum-based products with distinctive qualities. Similar to Hydroxypropyl Methylcellulose(HPMC) in the chemical structure, it can not only provide functions similar to cellulose, but also have very good compatibility with other additives in building. starch ether has a very small amount used in mortar products, and a.. read more →
