What type of plastic is the Ring doorbell

We have a mounting situation where we can't use screws. Looking at, e.g., Loctite® PL Premium® MAX construction adhesive, which we've used to bind plastic to metal in the past, reliably. But that adhesive is contraindicated for Polyethylene, polypropylene, polytetrafluoroethylene (PTFE), and flexible vinyl (FPVC). Just wondering what plastic the Ring camera housing is made out of. Thanks!
