Product Description

Industrial gelatin is light yellow or brown grain which can pass the 4mm aperture standard sieve. The product is under the QB/T******4 national trade standard. we can handle the SGS ITS quality certificate and CIQ veterinary sanitation certificate and the note for changing the certificate of letting pass.

It mainly used in coating and sizing, paper manufacture, printing processes, protective colloidal applications, matches, coated abrasives, adhesives, gelatin films and light filters, cosmetics and so on.

Technical gelatins are used in the warp sizing of rayon and acetate yarns. The gelatin size adds strength to the warp and resistance to abrasion so that breakage of the warp is minimized. Gelatin is particularly well suited for this application because of its excellent solubility and film strength.It is applied in aqueous solution along with penetrating oils plasticizers and antifoam agents before weaving and later removed during finishing by washing with warm water.

Panama hats are sized with gelatin. Sizing helps preserve the sharp of the hat while imparting resistance to water and dirt. An emerging technology involves the use of gelatin to size quartz fibers for space- age fabrics.

Gelatin is used for surface sizing and for coating papers. Either used alone or with other adhesive materials the gelatin coating creates a smooth surface by filling up the small surface imperfections thereby ensuring improved printing reproduction. Examples include posters playing cards wallpaper and glossy magazine pages.

High quality rag- based papers such as those used for blueprints and currency also feature a gelatin size coating. The result is a paper which has good moisture and abrasion resistance as well as good adhesion to printing inks. During manufacture the gelatin coatings are rendered insoluble by treatment with  cross- linking agents.

The permanent crinkle in crepe paper is the result of gelatin sizing.

For over a century gelatin compositions have been used in printers rollers and plate wiping rollers for multicolor presses and offset lithography. Several photo-printing methods depend on the effect of light on a gelatin film which has been sensitized by treatment with potassium or ammonium dichromate. Examples of printing applications include carbon printing collotype printing silk screen printing and photogravure printing.
