what is the number of Thermal Conductivity , Thermal resistance and density ?

It's listed on the bottom of the page. Specific Gravity: 2.50 g/cm3 Thermal Conductivity: 8.5 W/(mK) Volume Resistivity: 3.8 x10^13 ohm-cm

I know this good for ps4 but can pad be good too and what size.

There's enough in it that it should be good for any size CPU.

La pasta termica tiene fecha de caducidad o de vencimiento?

hola amigo, mientras tengas la pasta a temperatura ambiente y en su caja o su defecto en en lugar oscuro te puede durar muchos años, en la caja de igual forma no generan fecha de vencimiento, y la verdad te la recomiendo 100% la he utilizado en todos mis portátiles y en dos consolas ps3 y si nota su mejora ante recalentamientos ni los video juegos ni los portátiles se me apagan

Will this product work on a vertical surface? Or, once it heats up will it drip?

Yes, this will work just fine in a vertical surface. Most CPU's in PC's are mounted vertical and that's what this is designed for.
