What is the glass transition temperature of a polymer?
between 170 K to 500 K.
The value of Tg depends on the mobility of the polymer chain, and for most synthetic polymers lies between 170 K to 500 K. The transition from the glass to the rubber-like state is an important feature of polymer behavior, marking a region of dramatic changes in the physical properties, such as hardness and elasticity.
What is the melting point of nylon 66?
515.9°F (268.8°C)Nylon 66 / Melting point
How is Tg value calculated?
Tg is typically calculated by using a half-height technique in the transition region. The heating rate and sample heat history are a couple of factors that may affect the test result. Depending on the equipment capability, DSC can be used for a wide range of thermoplastic and thermoset polymers.
Why TC is higher than Tg?
It should be noted that the crystallization peak (Tc) is at a higher temperature than the Tg. A temperature above the Tg allows more freedom of movement of the polymer’s molecules.
What is maximum operating temperature of nylon?
Nylons are also known to be resilient and non marring, have high impact resistance has a continuous operating temperature of about 180º F, and a relatively light weight that makes it ideal for use in mechanical and electrical hardware to ease maintenance and replacement procedures.
Why does nylon 66 have a high melting point?
Nylons are polyamides, formed by the reaction of an amine with an acid. The amide group is responsible for nylons’ relatively high melting point, strength, and affinity for moisture.
