Buna Rubber cutting speeds

I am looking for feeds and speeds for 1/8" duro 50a Buna Rubber. Has anyone cut this rubber before? I have a 130w reci tube and looking for some guidance prior to test cutting the rubber.

I found 2.3 mm stamp pad rubber cut perfectly at 10 mm/s with 75% of a 60 W laser:

I don’t know what kind of rubber they use for stamps, but it didn’t smell like a tire fire … :grin:
