    Marking Santoprene with a Fiber Laser?

    Hello,
    I am interested in knowing if anyone has marked on santoprene with a fiber laser and what the results are.
    I have heard that it can be done, and that it leaves a white mark (maybe on a black part).
    I am curious to know how well the "white" mark will hold up to handling and outdoor exposure.
    Thanks for any replies.

    Santoprene TPV is a dynamically vulcanized alloy consisting mostly of fully cured EPDM rubber particles encapsulated in a polypropylene (PP) matrix
    EPDM rubber is very similar in appearance and feel to basic tire innertubes, and polyprop is what plastic storage containers are made of-- someone figured out how to marry the two and call it Santoprene... never heard of it, seems a bit soft-ish for fiber lasering but who knows, I find out something new every day about these things!

    (sorry I'm not much help!)

    You SHOULD be able to color change the colorant. Prior company used to buy and injection mold and the pellets were an off white and we added brown colorant.
