PA is a subcategory of Polyamide. Its elastic modulus ranges from 275 to 410 MPa. Its flexural modulus ranges from 306 to 400 MPa. Its tensile strength ranges from 7600 to 14000 MPa at break. Its flexural strength ranges from 10000 to 16400 MPa. Its Izod Impact strength ranges from 0.8 to 3.5 J/cm. Its elongation at break ranges from 40 to 150 %. Its hardness ranges from 77 to 93 Rockwell M. Its specific gravity ranges from 1.01 to 1.19. Its coefficient of thermal expansion ranges from 28 to 70 x 10-6/°C. Its molding pressure ranges from 5 to 20 MPa.
Polyamide, also known as PA, is a thermoplastic polycondensate. Common trade names are Ultramid and Zytel. aromatic, amorphous transparent copolymer It has high lubricity and moderate strength. It is tough, inexpensive, but has poor dimensional stability due to water absorption (hygroscopic nature). PA is commonly used to make high-lubricity parts such as bearings, blow moldings molds, and clothing fabrics.
