Item Description：

Material: Nylon PA66 Flame class: 94V-2 The characteristics of:
PA66 plastic is one kind has the plasticity of translucent or opaque white or yellowish granular crystalline polymers, advantage:
1.Light weight, density (g/cm3): 1.10-1.14.
2. excellent mechanical properties. The mechanical strength of Nylon high, good toughness: Rockwell hardness: 118; impact strength (kJ/m2): 60-100 (MPa):60.0-80.0; tensile strength; bending strength (MPa):100-120; bending elastic modulus (MPa):2000 ~ 3000.
3 self lubrication, abrasion resistance. Nylon has good action self lubrication, the friction coefficient is small, and thus, as the transmission components of its long service life.
4.Excellent heat resistance: brittle temperature of -30 DEG C; the melting point of 252 DEG C; thermal decomposition temperature greater than 350 DEG C; continuous heat resistant 80-120 C.
5 excellent electrical insulation properties: volume resistivity (omega cm): 1.83 x 1015; dielectric constant =1.638 (Note: the air dielectric constant =1.000585, 20 degrees of water dielectric constant of =81.5).
6 excellent weather resistance.
7 equilibrium water absorption rate: 2.5% (Note: igneous rock water solid ratio is less than 1%, the water absorption rate of sedimentary rock compaction around 3%).
8.PA66 to acid, alkali, salt solution, the majority of Halon, hydrocarbons, esters, ketones and other corrosion.
In a word, using PA66 as the raw material for the production of fasteners, mechanical performance and security, no rust, beautiful light, suitable for the vast majority of the work environment.
