Connecting Electricity with Flexibility: A New Option in Conductive Rubber
"Adding a large amount of conductive filler makes rubber hard."
This long-standing belief is beginning to change.
From electronic devices and automotive components to medical sensors, conductive materials—those that carry electricity—are becoming increasingly common in our daily lives. Among them, conductive rubber is a particularly challenging material, as it must balance both flexibility and conductivity.
Traditionally, achieving sufficient conductivity required adding large amounts of conductive fillers such as carbon black or metal powders. This inevitably led to a trade-off: the rubber became harder and lost its softness.
Moriroku’s Technology Brings “Soft Conductive Rubber” to Life
Harnessing Advanced Dispersion Techniques
Moriroku has successfully unlocked the full potential of carbon nanotubes (CNTs)—known for their exceptional conductivity—through its proprietary high-dispersion technology.
This breakthrough enables high conductivity with significantly lower filler content, while preserving the inherent softness of rubber.
The resulting “soft conductive rubber” is now showing promise in applications where hardness was previously a limitation, gradually expanding the possibilities for product design.
Low-Hardness Conductive Rubber: Correlation Between Volume Resistivity and Hardness
Moriroku’s newly developed soft conductive rubber achieves a rare balance between low hardness and high conductivity—something that conventional low-hardness carbon black or metal fillers have struggled to deliver.
