Introduction Chinese alias: Nylon 66 staple fiber; polyhexanediamide; Nylon -66; nylon 66 resin; polyamide -66; polyhexanediamine; Nylon -66. Nylon 66 has high fatigue strength and steel property, good heat resistance, low friction coefficient, good wear resistance, but high hygroscopicity and poor dimensional stability. Generally used for medium load, using temperature & LT; degrees without lubrication or less lubrication conditions of wear-resistant force transmission parts. II thermal properties melting point (TM) melting point is the temperature of crystallization melting, showing clear melting point for crystalline polymer nylon-66. According to the adopted test method, the melting point fluctuates in the range of 259 ~ 267 ° C. The melting point of nylon-66 measured by differential thermal analysis (DTA) is 264 ° C. In fact, the melting point of nylon-66 can be calculated according to the melting heat (ΔH) and the melting entropy (δs) of the crystallization: the ΔH of nylon-66 is 4390.3 J/mol, the ΔS is 8.37 J/KMOL, and the theoretical value of TM is 259.3 ° C [] . The melting point of nylon-66 is 246 ~ 263 ° C if the temperature at which the volume expansion coefficient shows the maximum value is taken as the melting point. The theoretical melting temperature is 259 ° C. Glass transition temperature (TG) the specific volume and specific heat capacity of polymers can change irregularly at a certain temperature, which is the glass transition temperature, it is the temperature at which the segments of a molecular chain begin to move, overcoming the forces between the molecules. At this temperature, the modulus, vibration frequency, dielectric constant and so on also begin to change. The glass transition temperature of Nylon -66 is related to the test method, moisture content, monomer concentration and crystallinity of the sample. Wilhoit and Dole considered that the glass transition temperature of NYLON-66 was 47 ° C [] , while Rybnikar determined the specific volume of nylon-66 at low temperature, it is found that there is also a transition temperature at -65 ° C in nylon-66[] .
