Usage:
1. The third monomer of acrylonitrile fibre; The acrylonitrile fibre, which takes
Itaconic acid as the third monomer, is easy to dye.
2. Adhesive: The plastic and coating with the application of 1%-5%
itaconic acid and styrene complex have the features of light color, easy separation, waterproof and anticorrosion.
Itaconic acid can be used in producing high intensity resin glass fibre.
Itaconic acid is also used in carpet coating and book cover.
3. Binding material: Acrylic acid emulsion with
Itaconic acid is excellent adhesive for non intertexture fibre products. Adhesive with
itaconic acid, PVC monomer is also excellent adhesive for paper and celluloid.
4. Teeth adhesive: Teeth adhesive, made up of aconic acid, acrylic acid and metal oxide, has excellent compression resistance and physiological adaption.
5. Special lens: Polymer with
itaconic acid has special luster and transparency.
Itaconic acid is suitable to the production of artificial gem and special lens.
6. Detergent: Polymer of
itaconic acid
and acrylic acid is a kind of macromolecular chelating agent.
Itaconic acid can be used in cleaning boilers and cooling equipment.
7.
Itaconic acid and esters are excellent additive for producing synthetic resin, cation exchange resin and surface active agent.
