e-Therm 150

Thermaly Conductive Insulating Rubbers

 Download as PDF
e-Therm 150 is a silicone rubber filled with conductive fillers and reinforced with fiberglass. This low cost material is ideal for transferring heat from electronic components while providing electrical insulation from heat sinks, where cost is also an important factor.
 
High thermal conductivity.  e-Therm150
High dielectric strength.
High thermal resistance and stability.
Thermal performance improves with age.
Effective over a wide range of temperature.
Reinforcement keeps also thin sheets resistant to tear.
Greaseless, non-flowing, non-cracking, one component material.
Flame retardant.
Chemical resistance for process cleaning agents.
Available in sheets or custom die-cut parts.
Standard thicknesses: 0.23, 0.30, 0.45, 0.80 mm.
Available also with pressure sensitive adhesive.
