I would literally translate that to being exclusively kinetic as it is fashioned towards being armor.  Thus, following real life examples of kinetic dispersal upon impact (i.e trauma reduction) such as kevlar, it would make sense to me that that's as far as it goes.  Electrical or Thermal energy would come down to insulation since it's not something one can absorb safely.  Thermal energy is heat.  Absorbing too much heat would be very detrimental to the human anatomy and Electrical should explain itself.  I agree with Tackyhillbilly concerning gravitational and magical as well.<br/><br/>When you're blasted with a energy attack that is thermal based, such as fire or ice - I often call into question how a fireball possesses concussive force as we've seen in multiple hollywood depictions or fictional iterations.  Then, with a second thought, I realize it's the velocity (thus energy in motion) behind the blast that delivers the kinetic impact to accomplish that.<br/><br/>However, I want to point out that despite whatever amount of a beating any piece of armor can take, there is obviously a threshold point where the kinetic dispersal is not negated enough to prevent transfer of energy to the person wearing the armor.  So, while Deathstroke's armor may be nearly impenetrable by conventional means or can withstand a punch from Superboy uninhibited, there will be blows that bypass that so the mitigation is not absolute.  This is a personal preference however.  I dislike comic book's portrayal of unavoidable variables and absolutes. That doesn't make for interesting storytelling.
