THUBBER

Thermally conductive rubber that combines the compliance and elasticity of soft silicone rubber with the thermal conductivity of metal

THERMALLY CONDUCTIVE RUBBER

Thubber is an elastomer composite that is softer than skin (elastic modulus < 100 kiloPascals), stretchable (strain limit > 600%), and thermally conductive (up to 10 Watts per meters-Kelvin).  These composites have the mechanical properties of soft silicone rubber and a thermal conductivity that approaches stainless steel.

DURABLE AND TEAR RESISTANT

Thubber has 50x the tear resistance of other soft elastomers like silicone rubber that have a similar compliance and elasticity.  This resistance to tearing comes from the high amount of mechanicalenergy required to propagate a tear.  The fracture toughness is over 10,000 Joules per square meter.

As electronics and electromechanical components become smaller, more powerful, and more pervasive, there is an increasing need for thermal interface materials (TIMs) that can transfer heat produced during operation.  These TIMs should be soft and deformable enough to minimize air gaps at the interface.

Arieca is Hiring

We’re currently looking to hire engineers to help on a NASA-funded project to use Thubber in space suits, deployable systems, and other space-related applications:

  • Research Intern – Develop new formulations of Thubber for enhanced performance or use in extreme environments; experimental heat analysis and temperature mapping; feasibility studies that predict performance using computational heat analysis; 6 mo. appointment with opportunity for transition to full-time position
  • Design Engineer – Create testbeds to evaluate the performance of Thubber for thermal management in space-related hardware applications; electronics and mechatronics design and integration into elastomeric wearable or deployable systems; experimental heat analysis and temperature mapping of prototype systems; full-time position with opportunity for annual renewal

Both positions start September 1, 2018.  Interested candidates should email the following to Carmel Majidi (cmajidi@arieca.com):

  • Applicant’s statement (1 page max) that summarizes background and interests
  • Resume or Curricula Vitae 
  • Contact information for three references who we can contact for recommendation letters
