Nylon(PA) is the most important engineering plastics. The product is widely used in almost every fields and it’s the most widely used plastic of the five engineering plastics. There are many types of nylon, including nylon 6, nylon 66, nylon 11, nylon12, nylon 46, nylon 610, etc. However, nylon 6 and nylon 66 are the most important varieties and the output of nylon 6 and nylon 66 are dominant.
PA6 is a translucent or opaque milky crystalline polymer which is made of polymerization of caprolactam monomer at hightemperature. The material has the most superior comprehensive performance including mechanical strength,
stiffness, toughness,mechanical shock resistance and wear resistance. All these properties combined with good electrical insulation and chemical resistance make PA6 a general purpose grade material for manufacture of mechanical components and maintainable parts.
Properties
1. High mechanical strength, good toughness, high tensile and compressive strength
2. Excellent fatigue resistance
3. Smooth surface with low friction coefficient, good wear resistance
4. Corrosion resistance, resistant to alkali, most salt solutions, weak acids, engine oil and gasoline
5. Non-toxic, inert to bioerosion, good antibacterial and antiviral ability
6. Heat resistance, wide temperature range for using, can be long-term used at -40℃ to 100℃
7. Excellent electrical performance, good electrical insulation
8. Not resistant to strong acids and oxidants
9. Poor light resistance and dye ability
