PROPERTIES OF NYLONS THAT WE USE:

GENERAL

Nylons are generally strong, tough, and resilient polymers
Nylons offer good barrier and high fatigue properties
Nylons offer good abrasion resistance
Nylons offer good resistance to oils, greases and solvents
Most common nylons used in spectacle frames is Nylon 6,6

PRIMARY PROPERTIES

Excellent impact resistance, good thermal stability
High abrasion and weathering resistance
Excellent flow properties
Good dielectric properties
Good resistance to a wide range of chemicals
Hypo-allergenic

A characteristic of nylon is that it has a tendency to absorb moisture. This is a characteristic that gives nylon its toughness. Upon initial injection (at manufacture) nylon frames are very hard and brittle. They are then left to cure so that they will absorb moisture from the air and soften. Once cured, they become very impact resistant. The curing or softening period takes 2-3 weeks.
