Hydroxypropyl starch ether (HPS)

Hydroxypropyl starch ether (HPS) is widely used in paper, textile, petroleum, and building materials industry. It provides very good rapid thickening capacity and has high water retention. It could improve the anti-sagging ability of the whole material, so that the material does not flow downward (slip) when smearing or pasting other materials, and has a good opening time. It has good lubricity, which can improve the operating performance of the material and make the operation smoother.
