HZOrganicChem Dibutyl Maleate (DBM)

通用系列： Additive -- Plasticizer • 提供方： Hangzhou Nature Organic Chemicals Co., Ltd

I Chemical formula and molecular weight

Chemical formula:C12H20O4

Molecular weight:228.29

CAS No.:105-76-0

II Properties and uses

Colourless, transparent oily liquid, b.p.280°C, freezing point -65~-80°C, viscosity 8 c.p.(20°C), refractive index 1.444(25°C).

Used as an interior plasticizer, may be copolymerized with monomers like vinyl chloride, vinyl acetate, styrene, etc. These copolymers are usually used in preparing coatings, films, adhesives, rubbers and fixing agent for pigments. When it used for the PVC ware, it can make ware soft, lucency, high transparence.

Due to its strong solublizing property, it may effectively plasticize polyacrylonitrile, polymethyl acrylates, which are difficult to be plasticized by other plasticizers.
