* Polyamide absorption characteristics


1. Moisture absorption of Polyamide

Polyamide absorbs moisture easily in comparison to most thermoplastics.

Moisture can cause bubbles, silver streaks, and material aging on the product if the polyamide molds with it.

Thus, sufficient pre-dehumidification and drying is required.

In addition, properties and size may change after molding. Water absorption occurs because of the chemical

structure of polyamide. Water passes through amorphous parts between the amide syntheses and enlarges

the distance between molecules.
