Alkyd Long Glass Fibre Reinforced; High Impact

Aug 14 2001

Advantages

Long glass fibre gives the highest tensile strength, oxygen index, and flexural modulus, notched izod impact strength and heat distortion temperature for alkyd grades within Plascams. Good elongation at break and mould shrinkage compared with other modified grades of alkyd.

Disadvantages

Highest linear expansion and cost 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.
