Neat GF PA examples of modulus retention versus temperature C

For long-term heat ageing, property retention depends on the property and grades considered, notably the heat stabilizers used. Characteristics such as elongation at break and impact strength are especially heat sensitive. 

At low temperatures, general-purpose grades generally have a brittle point of -65°C down to -80°C. 

These results relate to some grades only and cannot be generalized. 

Polyamides 6 and 66 are translucent to opaque according to the thickness and the grade. The refractive index can be, for example, in the range of F53 up to 1.565.
