Starch and maize dextrin - Import export

Cationic starch carries a positive charge over the entire pH range creating their affinity towards negatively charged substrates, such as cellulose, pulp and some synthetic fibres, aqueous suspensions of minerals and slimes and biologically active macromolecules. This starch may be derived from maize and is used primarily as a wet-end starch and mainly used in paper and cardboard forming processes: 1.Increases mechanical strength for better retention of fines and fillers 2.Enables faster drainage and improved sheet formation and production, saving both time and resources. 3.Improves opacity, brightness and stiffness of paper and allows for better printing quality 4.It is also popularly used in the manufacture of disposable diapers (nappies) and personal sanitary products.

Oxidized starches are highly versatile and are widely applied in paper and board making processes: Shorter chain lengths of these starches help to improve whiteness of paper and reduces microbiological content. Can be used as a surface sizing agent as they improve printability, fibre lay, fold and tensile strength. Are available in different viscosity grades and may be used in a coating binder or base as they improve ink fixing and gloss, reduce picking and demonstrate controlled binder migration. They are the preferred thickener for applications requiring gels of low rigidity and have also shown to improve adhesion in batters and breading. Oxidized starch has also been used in the making of construction materials such as concrete blocks, gypsum board and fire-resistant wall- boards. Applications: 1.Paper production 2.Coating binder 3.Construction materials: concrete blocks, gypsum board. 4.Plywood adhesives 5.Colour pigment binder

Spray starch derived from either maize or tapioca is applied by means of spraying and is used primarily in the production of paper, boards, and ply. This modified starch: 1.Increases the strength of ply bonds in boards and plywood. 2.Increases the bending and spring back tendency of boards. 3.Reduces the delamination of plywood and laminated boards.
