Tailpad foam kick

Hey guys, Ive had an idea for a surfboard accessory that i want to prototype and need to find the correct material for it, does anyone know the product name of the foam used in the kick part of a normail tailpad/grip? only the kick part as it seems like a relatively solid high density foam, ive been searching around but not really sure how to go after it. Also if I needed it to be stiuck onto the board a bit stronger than a regular tailpad, what kind of 3m adhesive would you think to go for, and assuming higher strengths of it wouldnt react badly with the epoxy skin type of boards, like santa cruz epoxys…

Cheers for anyone with any insight for me

Chris
