Polyacrylonitrile/PAN/CAS:25014-41-9

Description:

Polyacrylonitrile is a kind of synthetic resin manufactured through the free radical polymerization of acrylonitrile. It belongs to the acrylic resin family. It is thermoplastic, and is resistant to most solvents and chemicals because of the strong chemical bonds formed between the nitrile groups. It is a kind of versatile polymer which can be used to produce many kinds of products such as fibers for textiles, ultra filtration membrane, carbon fiber and hollow fibers for reverse osmosis. Its homopolymer can also be used as fibers in outdoor awning, sails for yachts, and fiber-reinforced concrete. It can also be used for production of inherently flame resistant (FR) fabrics.

Specification

 Usage

Due to its special properties such as stability to UV degradation, low density, high strength and modulus of elasticity, thermal stability, non-fusibility and chemical resistance, Polyacrylonitrile is an important polymer for a wide range of applications.Thus, it is used in textile applications due to its wool-like characteristics, in the making of carbon fiber, filtration membranes, fibers for cement reinforcement, sails for yachts, awning fabrics in outdoor applications, specialist fibers for acoustic and thermal insulation, anti-flame fibers and in the production of felts for hot air filtration systems.
Copolymers containing polyacrylonitrile, which are flame-retardant, are used asfibers to make knitted clothing, like socks and sweaters, as well as outdoor productslike tents. Poly(acrylonitrile-co-butadiene-co--styrene)(ABS) and Poly(styrene-co-acrylonitrile)(SAN) are used as plastics. ABS is a lightweight and very strong polymer. It is so light and strong enough to be used in the production of automobile body parts.Thus, this material render automobiles'lighter using less fuel and thus polluting less.
The strength of ABS emanates from the nitrile groups that are present in its acrylonitrile units. The nitrile groups are very polar; hence, they can be attracted to one another. This occurrence permits opposite charges on the nitrile groups to stabilize one another. This strong attraction holds ABS chains very tightly, thus, itmakes the material very strong.Furthermore, the rubbery polybutadiene present in it makes ABS a tough polymer.
