| | | | PA66, say again nylon 66 |, Gather the adipic acid adipic amine; Nylon 66 | | | | NY66, abbreviations. The patent: [NH unit (CH2) 6 - NHCO (CH2) 4CO] n -
Properties:
Translucent or opaque crystals form polymers, ivory has plasticity. 115 g/cm3 density. Melting point 252 ℃. ℃ embrittlement of temperature - 30. More than 350 ℃ its thermo-decomposing temperature. Continuous heat-resistant 80-120 ℃, balance bibulous rate 2.5%. Can the acid, alkali, most inorganic salt solution and halogenated cyclodienylsilane, hydrocarbons, esters, ketone corrosion, but soluble in phenol, formic acid etc nonpolar solvent. Has good abrasion resistance, self-lubricity, high mechanical strength. But large water imbibition, consequently size poor stability.
Appearance white bag or with the yellow granular
Density (g/cm3) 1.10-1.14
Tensile strength (MPa). 80.0 0-60
Rockwell hardness 118
The impact strength (kJ/m2) 60-100
Static bending strength (MPa) 1 00-120
Martin heat-resistant (℃) 50-60 bending elastic molus star (MPa) 2000 ~ 3000
Volume resistivity (Ω cm) standing 1.83 x 1015
Dielectric constant 1.63
Application:
It is widely used for manufacturing machinery, auto, chemical and electrical devices parts, such as gears, roller, pulley, the roller, the pump body, impeller, fan blades in high voltage seal wai, seat, gasket, bushings, various handles, supporting frame, wire packet layer etc. Also made films used as packaging material. In addition, still can be used to proce medical equipment, sports goods, daily necessities, etc.
| | PA66 physical and chemical properties of the features:
| | PA66 performance (physical) :
| | PA66 polyamide materials in higher melting point. | | PA66 at higher temperatures also can maintain strong intensity and rigidity. After | | PA66 in molding still has hygroscopic, mainly depends on the degree of material composition, wall thickness and environmental conditions. In the proct design, must consider hygroscopicity of geometrical stability influence. In order to improve the mechanical properties | | PA66, often join various modifier. Glass is the most common additives, sometimes in order to improve the shock resistance also join synthetic rubber, EPDM, SBR and other such as. | | PA66 viscous is low, the liquidity good (but not as PA6). This property can be used for machining very thin components. The viscosity is very sensitive to temperature changes. The | | PA66 shrinkage in 1% ~ 2% between, join glass fiber additive can rece shrinkage to 0.2% ~ 1%. Shrinkage in flow direction and flow direction in the vertical direction by different is larger. | | performance (chemical PA66 | | PA66) : for many solvent resistance soluble, but to acid and some other chlorinated agent resistance is weak.
