PURmix® Conductive Compounds for Silicone Rubber

At NovationSi, we specialize in custom silicone solutions that push the boundaries of innovation for mixers and fabricators. Our new line of PURmix® Conductive Compounds for Silicone Rubber lets you achieve the optimal balance between electrical conductivity and elastomeric integrity. Customizable to meet specific electrical, mechanical, and environmental requirements, these compounds enable next-gen designs in healthcare, transportation, energy storage, electronics, and beyond.

The Science Behind Conductivity

Silicone rubber can be modified to conduct electricity through precision filler loadings. By selecting advanced conductive fillers with high aspect ratios, PURmix® compounds achieve consistent conductivity with less fillers—preserving mechanical properties while delivering electrical performance.
