Distinguish between amorphous and semi-crystalline thermoplastics
Discover hot gas (nitrogen) welding

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.
