If it's known at all, you will find Young's modulus for BVC in units of Pascals (Newtons/meter^2) or PSI.  A Newton, as you know, is a kgm/s^2.  A mass of one kg in the earth's gravity exerts a force (m*g) of 9.8 Newtons.  To convert kgF/mm^2 to Pascals, multiply by 9.8e6.  

This probably won't help, but Pyrex has a Young's modulus of approx. 1e7 PSI and a Poisson ratio of roughly 0.2.

1 Pascal = 1.45e-4  PSI
