pa6 1013b应用于电子电器,工业应用,汽车部件--密度:1.14 g/cm3 吸水率:1.8% 成型收缩率:1.4 % 热变形温度:75 ℃

it can absorb 8% when the water absorption is relative tothe saturation of moisture absorption, and the service temperaturecan be between 45 ~110 c. melting point: 218-290 c. the suitablewall thickness is 2.2-3.6 mm. the mechanical properties of pa6,such as tensile and compressive strength, vary with temperature andmoisture absorption. because the melting temperature of pa6 isabout 220 c, it has a wide processing range. compared with pa66, ithas better impact resistance and solubility, but strongerhygroscopicity. in order to improve the mechanical properties ofpa6, various modifiers are often added. glass fiber is the mostcommon additive, sometimes toughening agent is added to improveimpact resistance

although pa6 has many advantages, it also has some shortcomings,especially the poor notch impact performance under dry and lowtemperature conditions, which limits its application in dry andcold environments. therefore, the toughening research of pa6 underdry and low temperature conditions is of great significance. thefollowing is a brief introduction to the recent research status oftoughening of pa6. toughening of nylon 6 has been an importantsubject of nylon modification since 1970s. there are three mainways to obtain high toughness nylon 6 blends: blending withpolyolefins and elastomers; blending with high toughnessengineering plastics; and toughening with inorganic particles.

pa6 was first developed by the german basf joint venture companyin the late 1930s, and was formally industrialized in the early1940s. polyamide macromolecule structure contains a large number ofamide groups, the end of which is amino or carboxyl group. it is asemi-crystalline polymer with strong polarity, hydrogen bonding andcertain reactivity. pa6 has excellent comprehensive properties:high strength and good toughness in wet state; oil resistance,organic solvent resistance, chemical resistance; small frictioncoefficient, excellent self-lubrication performance; goodprocessing performance, so it has been widely used, such asautomobile, electronic and electrical, machinery, packaging,weapons, communications, aerospace, office machinery, householdappliances, construction, daily necessities, sports goods, etc.domain, especially automobile, electronics, packaging and otherindustries, consumption has been on the rise.
