Alkyd - Short Glass Fibre Reinforced

Apr 23 2001

Advantages

Short glass fibre gives the lowest mould shrinkage and highest elongation at break for alkyd grades within the Plascams database. Good notched izod impact strength, heat distortion temperature and density compared with other modified grades of alkyd.

Disadvantages

Low tensile strength, flexural modulus and oxygen index compared with other modified grades of alkyd.

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.
