PA (Polyamides) Plastic

What is PA Plastic?

Polyamides or Nylon is a major high performance engineering thermoplastics class because of its good balance of properties. Polyamides contain repeating amide linkages i.e. –CO-NH–. It is formed by condensing identical units, copolymers with different units.
There are various types of PA plastic are available. Polyamide is easy to work with and guarantees quality.
PA plastic has good mechanical properties and this plastic is mainly used in mechanical engineering.
PA Plastic is categorised as a technical plastic and is also known as an engineering plastic. Polyamide, more familiarly known as Nylon, is an extremely abrasion-resistant plastic.

These are including: Polyamide 6 (PA6), Polyamide 12 (PA12), Polyamide 66 (PA66), Polyamide 69 (PA69), Polyamide 6-10 (PA6-10), Polyamide 6-12 (PA6-12), Polyamide 46 (PA46), Polyamide 1212 (PA1212)
Typically, polyamides (or Nylon) are made from polycondensation of diacid with a diamine or by ring-opening polymerization of lactams with 6, 11 or 12 carbon atoms.
The monomers may be aliphatic, semi-aromatic or aromatic (aramids).
They may be amorphous, semi-crystalline and of greater or lesser crystallinity.

Polyamide 6 (PA6 Plastic) is also known as Nylon 6 or polycaprolactam. It is one of the most extensively used polyamides globally. It is synthesized by ring-opening polymerization of caprolactam. Melting point of polyamide 6 is 223°C.
PA6 Plastic is Caprolactum of Monomer(s)

PA66 Plastic is Hexamethylene Diamine/ Adipic Acid of Monomer(s).
Polyamide 66 (PA66) or Nylon 66 is one of the most popular engineering thermoplastics and is majorly used as a replacement to metal in various applications.
Nylon 66 is synthesized by polycondensation of hexamethylenediamine and adipic acid (two monomers each containing 6 carbon atoms). Melting point of polyamide 66 is 255°C.

PA12 Plastic is Laurolactam of Monomer(s)
Polyamide 12 (PA12) or Nylon 12 is a semi-crystalline thermoplastic which shows performance similar to Polyamide 11.
It can be derived from both petroleum and renewable sources. It is an expensive polymer as compared to other polyamides.

PA46 Plastic is 1,4-Diaminobutane/ Adipic Acid
Polyamide 46 (PA46) or Nylon 46 is manufactured by polycondensation of adipic acid and 1,4-diaminobutane.
Diaminobutane is synthesized from acrylonitrile and HCN.
Melting point of polyamide 46 is 295°C.

PA6-10 Plastic is Hexamethylene Diamine/ 1,12-Dodecanedioic Acid of Monomer(s)
Polyamide 6-10 (PA 6-10) is a semi-crystalline polyamide. PA 6-10 is produced by the polymerization of hexamethylene diamine with a dibasic acid i.e sebacic acid this this case.
Melting point of polyamide 6-10 is 223°C.
