These are similar in nature to the edible and pharmaceutical gelatins.

Technical gelatins have many and varied applications.

Matches
Gelatin binds together the chemicals that form the match head.

Coated adhesives
Gelatin is the binder between the paper and the abrasive particles in sandpaper.

Gelatin-NCR-paperMicro-encapsulation
The best known use of gelatin for micro-encapsulation is in NCR (‘no carbon required’) papers. A dye is micro-encapsulated in gelatin that forms a fine coating on a sheet of paper. With pressure exerted by hand writing or typing onto the top of the sheet, the micro capsules break onto the next sheet, forming a perfect copy of the first.

 

Spray drying and micro-encapsulation applications are numerous, and by using edible gelatins the process can be used in drugs, flavours and fragrances.
