To increase thermal conductivity for heat dissipation in plastics, compounders have traditionally included conductive additives like metals, graphite or carbon black in the compound. The required concentration of these additives not only impacts the mechanical performance of the plastic, but also tends to limit the transparency of materials.
Materium’s graphene nano-platelets have already shown their positive impact on thermal conductivity in PP, with up to 60% higher thermal conductivity at a mere 1% wt. loading.
Moreover, Materium can provide graphene which also maintains the transparency of the original matrix material. At a 1% wt. loading in LDPE, we achieved a 0.43 W/mK thermal conductivity level in a transparent compound.
