May be this group of thermoplastics can be the most known one. Appplcations of polyamide polymers are very important in engineering or daily life. In here, we give information about the properties and applications of polyamid group of polymers.
If we take a look at the chemical structure of molecular structure of polyamides, these are have amide bondings in long chains of polymer structures. The most important and known polyamide materials is nylons. Nylons have two major group according to the C atom number inside their monomers; nylon6 and nylon 6-6. General properties of nylons are;
General applications of nylons can be listed as;
Aramids(aromatic polymers) are very important polymer group in polyamides. They are used as reinforced plastics which has commercial name of ‘Kevlar’. It shows mechanical strength as steels, but the weigth of these aramids is around 20% of steels.
Nylon 6-6 has a symbol that PA6-6 and production method of Nylon 6-6 is step polymerization. Glass transition temperature of Nylon6-6 is around 50C and melting temperature is around 260C. Nylon 6-6 has highly crystalline structure which gives its mechanical properties. Nylon6-6 has modulus of elasticity value of 700 MPa and tensile strength value of 70 MPa. Nylon6-6 has very good elastic behaviour that has 300% of elongation according to its original shape.
These are the general properties and applications of polyamides and nylons. Do not forget to leave your comments and questions about polyamides below. Your precious feedbacks are very important for us.
