CTIRS-01 SWCNT Silicone Pre-Dispersion, 10 wt% in PDMS

Description

CTIRS-01 SWCNT Silicone Pre-Dispersion, 10 wt% in PDMS

Our CTIRS-01 is a 10 wt% SWCNT paste in a PDMS carrier for LSR, RTV and similar silicone systems. At extremely low addition it gives silicone rubber excellent electrical properties while minimizing impact on mechanical properties and allowing flexible multi-color formulation. It is a permanent antistatic alternative to carbon-black-loaded black silicone.

The paste is made with our high purity SWCNT (1-2nm, length over 100um, 99.5 wt%), the same tubes sold as SKU 0111.

Core characteristics

• No significant changes to existing formulations or production equipment; convenient to implement.
• Extremely low addition with minimal effect on mechanical properties; supports multi-color coloring.
• Significantly and permanently reduces surface and volume resistivity.

Dispersion instructions

• 10,000 mPa·s systems, addition below 1%: 50 mm dispersion disc at 1600 rpm for 20 min.
• 10,000 mPa·s systems with addition above 1%, and all 300,000 mPa·s systems: five passes on a three-roll mill.

Recommended evaluation

• We suggest an initial screen at 0.3%, 0.5% and 1.0% by total weight, then calibrating the final dosage with repeated multi-batch trials.

Sold per kg; minimum order 1kg.
