Nylon 6 fibers are tough, possessing high tensile strength, elasticity and luster. They are wrinkle proof and highly resistant to abrasion and chemicals such as acids and alkalis. The fibers can absorb up to 2.4% of water, although this lowers tensile strength. The glass transition temperature of Nylon 6 is 47 °C.
As a synthetic fiber, 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/cm3. Its melting point is at 215 °C and can protect heat up to 150 °C on average.
At present, polyamide 6 is the most significant construction material used in many industries, for instances in automotive industry, aircraft industry, electronic and electro technical industry, clothing industry and medicine. Annual demand for polyamides in Europe amounts to a million tones. They are produced by all leading chemical companies.
It is a semi crystalline polyamide. Unlike most other nylons, nylon 6 is not a condensation polymer, but instead is formed by ring-opening polymerization; this makes it a special case in the comparison between condensation and addition polymers. Its competition with nylon 6,6 and the example it set have also shaped the economics of the synthetic fiber industry.
High mechanical strength, good toughness, high tensile and compressive strength.
Corrosion resistant, very resistant to alkali and most salt liquids, also resistant to weak acids, engine oil, gasoline, aromatic hydrocarbon-resistant compounds and general solvents.
Self-extinguishing, non-toxic, odorless, weather resistant, inert to bio-erosion, good antibacterial and anti-mildew ability.
Excellent electrical properties, the electrical insulation is good, the volume resistance very high, and the breakdown voltage is high. In the dry environment, it can be used as a power frequency insulation material, and has good electrical insulation even in a high humidity environment.
The parts are light in weight, easy to matching color and molding. It can flow quickly due to its low melt viscosity.
