Typical Properties

What Is Polyacrylonitrile?

Polyacrylonitrile is a polymer of acrylonitrile obtained by copolymerization of acrylonitrile, methyl acrylate, and isaconic acid. It is the raw material for nitrile (commonly known as artificial wool). The chemical formula is [CH2=CH-CN]n with a structural average molecular weight of 2.5 x 104 to 8 x 104. It is white powder at room temperature and has a specific gravity of 1.14 to 1.16. The softening point is 267 ° C and the decomposition temperature is 230 ° C. It is almost insoluble in water, fat, weak acid, weak base, and general solvent. It is not soluble in body fluids such as saliva and gastric juice, either.

Usage

1. It is one of the main varieties of synthetic fiber. It is soft, light and warm. It is mostly used for blending with wool or as a wool substitute.

2. It is a high-strength, elastic, oil-resistant, and acid-resistant material. Artificial blood vessels made of it have been widely used in clinical practice.

3. Used as packing filler, fireproofing, and carbon fiber after weaving
