Nylon 6-PA (Polyamide)

Nylons are semi-crystalline polymers with a good range of properties. Nylons are widely used because they have a good cost to performance ratio. Lower numbered nylons — 6, 6-6, 4-6 — absorb moisture and change their properties as a result. Nylons have been compounded with reinforcements, fillers, and additives to produce a very wide variety of properties. Nylon 6 has the lowest modulus of all nylon grades.
