Machining Polyurethane 

Im also planning to buy 90A shore PU. do you know if its possible to drill in this material? also can it be cut with for example razor blades?

you can buy it in the raw like that? wonder if it would be better to buy it in liquid form and make your own. still cool! i didnt know you can do this

Hi, what PU type, shore hardness & the cutting disc type you are using to cut?

muito bom trabalho meu amigo

Which grade
