4. Distinguish between amorphous and semi-crystalline thermoplastics
4.1 Amorphous thermoplastics
Amorphous thermoplastics are easier to weld than semi-crystalline ones, because their behavior is predictable. In fact, each degree of softening corresponds to a further degree of softening.
This makes it easier to solder amorphous from semi-crystalline.
The sealing range is wider (10 to 20°C amorphous, 1 to 3°C semi-crystalline).
The material gradually softens.
In the event of overheating, smell followed by smoke and color give the alarm.
Heating power is lower.
Cooling is rapid.
