Polyamide 6/6 - Nylon 6/6 - PA 6/6 40% Mineral Filled

May 16 2001

Polymer Type

Thermoplastic

Advantages

Very good rigidity, tensile strength, creep resistance and processability compared with unmodified polyamide 6/6 grades. Reduced tendency to form sink marks.

Disadvantages

Processing equipment (screws and the like) needs to be cleaned mechanically rather than being burnt off. At high burn off temperatures minerals may fuse. Reduced notched izod impact strength when compared with unmodified grades.

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.
