Galaph I: Galaph I series are water Insoluble PVPP or Crosslink polyvinyl pyrrolidone (Crospovidone USP) as disintegration for         Pharmaceutical application. 

According to different swelling volume in water or alcohol we had two products of Galaph-IB6, it is high swelling volume and surface,  it demonstrate short disintegration  time using little quantity,  Galaph-ID2 has lower swelling volume and it is easy to be controlled during process.
