Temperature sensitivity of urethane

Temperature sensitivity of urethane

Temperature sensitivity of urethane

(OP)
Greetings,

I am interested in the hardening/stiffening of a urethane compound, adaprine (sp?) 162 and 167 with a change in temperature from 80F to around 10F.  Any info pertaining to this matter would be appreciated.  

Background:  This urethane is to be used as an energy absorber during a drop test.  Initial tests were conducted at around 80F and retesting may need to be done at colder temps.  Drop heights were calibrated at the 80F temp.
