AIE PA66 Plastic Raw Materials

الوصف

  PA*6 plastic materials for translucent or opaque milky package or with yellow granular crystalline polymer plasticity. Density (g/cm3) 1.***1.*4; tensile strength (MPa) *0 ***0.0; Rockwell hardness **8; m.p. **2 ° C; brittle temperature of **0 ° C; thermal decomposition temperature greater than **0 ° C; continuous heat to *****0 ° C; impact strength (kJ/m2) *****0; static bending strength (MPa) 1 *****0; Martin heat (° C) ****0; flexural modulus amount (MPa) ***0 ***0; volume resistivity (Ωcm) 1.*3 × ***5; equilibrium water absorption of 2.5%; dielectric constant of 1.*3. Chemical formula: [-NH (CH2) 6-NHCO (CH2) 4CO] n-resistant to acid, alkali, most of the inorganic salt solution, haloalkoxy, hydrocarbons, esters, ketones, such as corrosion, but soluble in phenol, formic acid, etc. polar solvent. Has excellent abrasion resistance, high mechanical strength, self-lubricating. But larger water absorption, and thus the poor dimensional stability of PA*6 polyamide material has a higher melting point. It is a semi-crystalline - crystalline materials. PA*6 at a higher temperature can be maintained strong strength and stiffness. PA*6 after molding still has hygroscopicity, and its extent depends mainly on the composition of materials, wall thickness, and environmental conditions. In the design of the product, be sure to consider the impact of hygroscopic geometric stability. In order to improve the mechanical characteristics of PA*6, often adding various modifiers. Glass is the most common additives, sometimes also added in order to improve the impact resistance of synthetic rubber, such as EPDM and SBR. PA*6, low viscosity, so liquidity is very good (but not as good as PA6). This property can be used to processing the thin element. Its viscosity is very sensitive to temperature changes. PA*6, shrinkage ratio in the range of 1% to 2%, the shrinkage can be reduced to 0.2% to 1% Glass fiber additives. Shrinkage in the flow direction and a flow direction of the phase differences on the vertical direction is larger. PA*6 many solvent with anti insoluble, but resistance is weak acid and some other chlorinating agent.
