China Factory Of HPS/ Hydroxypropyl Starch Ether
Excellent adhesive cellulose powder HPS to be chemical auxiliary agent
Hydroxypropyl starch ether (HPS)is a white fine powder obtained from natural plants through modification,high etherification and spray drying,without plasticizer.It is completely different from ordinary starch or modified starch.
Application
It can be used as an additive for cement based products,gypsum based producs and lime calciumd products. It has good compatibility with other building additives.When used together with hydroxypropyl methyl cellulose(HPMC),it can play a thickening role,promote internal structure,and have better crack resistance and improve workability. The amount of HPMC can be obviously reduced by adding modified starch ether(HPS).
