Polyamide 12 - Nylon 12 - PA 12 Flexible

Sep 16 2001

Polymer Type

Thermoplastic

Advantages

Very flexible, good abrasion resistance, good-notched izod impact strength and better elongation at break compared with unmodified polyamide 12.

Disadvantages

Reduced heat distortion temperature, increased coefficient of linear expansion and poor electrical characteristics compared with unmodified polyamide 12.
