Polyphenylene Oxide - Modified - PPO 30% Glass Fibre Reinforced; Fire Retardant

Aug 31 2001

Polymer Type

Thermoplastic

Advantages

Better tensile strength, flexural modulus, maximum operating temperature, heat distortion temperature and flammability characteristics compared with unmodified PPO. Halogen free flame retarding additives available.

Disadvantages

Significantly reduced elongation at break, reduced notched izod impact strength and electrical characteristics compared with unmodified PPO. A mould temperature of about 110°C (230°F) is recommended to avoid mouldings with moulded-in strain. Inclusion of glass can cause anisotropy 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.
