Polyphenylene Oxide - Modified - PPO 10% Glass Fibre Reinforced

Aug 31 2001

Polymer Type

Thermoplastic

Advantages

Improved tensile strength, flexural modulus, and oxygen index and heat distortion temperature compared with unmodified PPO.

Disadvantages

Reduced elongation at break, notched izod impact strength and electrical characteristics compared with unmodified PPO. High mould temperature (~110°C/230°F) required reducing strain in mouldings.

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.
