Introduction Chinese alias: Nylon 66 staple fiber;polyhexanediamide; Nylon -66; nylon 66 resin; polyamide -66;polyhexanediamine; Nylon -66. Nylon 66 has high fatigue strengthand steel property, good heat resistance, low friction coefficient,good wear resistance, but high hygroscopicity and poor dimensionalstability. Generally used for medium load, using temperature & LT;100 -120 degrees without lubrication or less lubrication conditionsof wear-resistant force transmission parts. II thermal propertiesmelting point (TM) melting point is the temperature ofcrystallization melting, showing clear melting point forcrystalline polymer nylon-66. According to the adopted test method,the melting point fluctuates in the range of 259 ~ 267 ° C. Themelting point of nylon-66 measured by differential thermal analysis(DTA) is 264 ° C. In fact, the melting point of nylon-66 can becalculated according to the melting heat (ΔH) and the meltingentropy (δs) of the crystallization: the ΔH of nylon-66 is 4390.3J/mol, the ΔS is 8.37 J/KMOL, and the theoretical value of TM is259.3 ° C [] . The melting point of nylon-66 is 246 ~ 263 ° C ifthe temperature at which the volume expansion coefficient shows themaximum value is taken as the melting point. The theoreticalmelting temperature is 259 ° C. Glass transition temperature (TG)the specific volume and specific heat capacity of polymers canchange irregularly at a certain temperature, which is the glasstransition temperature, it is the temperature at which the segmentsof a molecular chain begin to move, overcoming the forces betweenthe molecules. At this temperature, the modulus, vibrationfrequency, dielectric constant and so on also begin to change. Theglass transition temperature of Nylon -66 is related to the testmethod, moisture content, monomer concentration and crystallinityof the sample. Wilhoit and Dole considered that the glasstransition temperature of NYLON-66 was 47 ° C [] , while Rybnikardetermined the specific volume of nylon-66 at low temperature, itis found that there is also a transition temperature at -65 ° C innylon-66[] .
