ForTii Ace WX51-FC is a 30% glass-reinforced PPA based on nylon 4T chemistry with a high glass-transition temperature
of 160 C/320 F.
He says the resin has a glass-transition temperature
160[degrees]C, which is higher than other PPAs, including existing ForTii grades, and at least 80[degrees]C higher than PA66.
Ultem EXSP0023 features a glass-transition temperature
(Tg) of 245[degrees]C, has a dielectric strength of 4,700 V/mil and good tear resistance.
It produces a glass-transition temperature
of more than 120 [degrees] C, and high bond strength to glass ceramic, metals and most plastics--allowing it to pass the most stringent specifications for both single- and multimode terminations.
Making use of the fact that the glass-transition temperature
The glass-transition temperature
may be determined by taking the middle of the change in baseline (half-height method).
With a glass-transition temperature
of 450 degrees F, PPSF has the highest operating temperature and toughness of any rapid prototyping material except metals," he said.
Meanwhile, its modulus is 50% greater at temperatures below the glass-transition temperature
(Tg) of PEEK (302 F).
The tan[Delta] curves were highly reproducible, and the maximum error in the glass-transition temperature
was estimated to be 1-2 [degrees] C.
The new material is thermomechanically stable with an effective glass-transition temperature
(Tge) of over 400 C.
Amorphous PC exhibits only one transition temperature, known as the glass-transition temperature
Since the sperm are held for extended times close to -130 degrees C, the glass-transition temperature
of water, this places the sperm at risk of undergoing very slight deterioration with time.
