Characteristics of Beststarch water absorbent:IA Type water absorbent is mainly used in film blowing for regenerative plastic material. It will absorb the moisture in the process of the film blowing, which hasthe following advantages:a) No need to purchase the drying facility, rather than the conventional way.b) Drying operator is not needed, thus it will save the labor cost.c) It will also save the electricity cost in drying process.d) It will not cause any water loss rather than the traditional drying procedure.Water absorber can react to the moisture in the plastic and keep the weight ofthe products.e) Reduce one working procedure and the probability of material loss.Packing: Vacuum packing for the inner; carton packing for the outer

Appearance:                    light yellow liquidPH (1%water solution):           8 ~ 11                            Water-solubility:                easy to dissolve in cold waterAPPLICATION AND CHARACTERISTICS:·Farther improve the effect of color fixation with the reactive grouping in the molecule·Without and even unable to release free formaldehyde. According with the requests of the environment protection·excellently used in the fixation of the which dyed with the active, directed and acidic dyeing. INTRODUCTION OF THE USAGE ·Technological parameterDosage of fixing agent:     0.5% ~ 2%
