Static-dissipative compound goes a long way
PRE-ELEC ESD 6110 is a novel HIPS-based static-dissipative compound for static control applications.
Unlike silicone compounds, which are thermoset, there is minimal wastage with Preseal compounds.
Any scrap can be reground and moulded again.
Designed for mass production, Preseal compounds can be quickly and easily injection moulded into complex shapes and sizes with consistent quality.
They can also be extruded, or overmoulded onto HIPS, ABS, PC/ABS, PC, and PPO-PS for moulded-in gaskets.
Preseal compounds use silver as the conductive medium because it provides the highest EMI shielding.
In addition to providing EMI shielding, the compounds can be used for grounding and shock absorption, and as a heat sink due to the relatively good heat conductivity.
The new compounds have a maximum volume resistivity of 0.01ohm-cm, 100dB shielding effectiveness, and less than 35% compression set.
In addition to Preseal compounds, Premix manufactures other elastomers, utilizing electrically conductive additives, such as nickel or carbon, which can be customized to meet specific application requirements.
