Polyamide 11 - Nylon 11 - PA 11 Flexible

May 12 2001

Polymer Type

Thermoplastic

Advantages

Excellent abrasion resistance, better notched izod impact strength, lower tensile modulus, softer and more flexible than unmodified PA 11.

Disadvantages

Reduced heat distortion temperature, creep resistance and higher coefficient of linear expansion than unmodified PA 11. Poor retention of physical properties at temperatures above 95°C due to plasticiser loss.

How are Graphene Batteries Made?

The primary distinction between graphene-based batteries and solid-state batteries lies in the composition of either electrode. Although the cathode is commonly changed, carbon allotropes can also be employed in fabricating anodes.
