As seen in the table below, Nylon 11 has lower values of density, flexural and Young's modulus, water absorption, as well as melting and glass transition temperatures. Nylon 11 is seen to have increased dimensional stability in the presence of moisture due to its low concentration of amides. Nylon 11 experiences 0.2-0.5% length variation and 1. ...
Fluorinated ethylene propylene (FEP) is a copolymer of hexafluoropropylene and tetrafluoroethylene. It differs from the polytetrafluoroethylene (PTFE) resins in that it is melt-processable using conventional injection molding and screw extrusion techniques. [ 2 ]
The 428 °F (220 °C) melting point of nylon 6 is lower than the 509 °F (265 °C) melting point of nylon 66. [61] Homopolymer nylons are derived from one monomer. Monomer
Melting point: 1 to 3 °C; 34 to 37 °F; 274 to 276 K ... is an important precursor to the polymer nylon 66. In 2005, about one million tonnes of adiponitrile were ...
By far the most important application of 11-aminoundecanoic acid is its use as a monomer for polyamide 11 (also: nylon-11). Wallace Carothers , the inventor of polyamide ( nylon 66 ), is said to have polymerized 11-aminoundecanoic acid as early as 1931.
Nylon 12 exhibits properties between short chain aliphatic nylons (e.g., nylon 6 and nylon 66) and polyolefins. [3] At 178-180 °C, the melting point of nylon 12 is the lowest among the important polyamides. Its mechanical properties, such as hardness, tensile strength, and resistance to abrasion, are similar to those of nylon 6 and nylon 66.
The glass transition temperature of Nylon 6 is 47 °C. As a synthetic fibre, Nylon 6 is generally white but can be dyed in a solution bath prior to production for different color results. Its tenacity is 6–8.5 gf/D with a density of 1.14 g/cm 3. Its melting point is at 215 °C and can protect heat up to 150 °C on average. [4]
Nylon 1,6 (aka polyamide 1,6) is a type of polyamide or nylon. [1] Unlike most other nylons, nylon 1,6 is not a condensation polymer, but instead is formed by an acid-catalyzed synthesis from adiponitrile, formaldehyde, and water. The material was produced and studied by researchers at DuPont in the 1950s. [2]
