Smartphone car holder damage prolonged hot sun (suction rubber base made by plastic) topic

Been using smartphone car holder quite number of times. I'm living in tropical country. The suction rubber connection to the base mostly made plastic. This always damage like crispy cracker. The rubber and everything else are fine. I'm looking smartphone holder which the base to the rubber not made by plastic. Maybe the plastic are not designed in prolong hot temperature.

Anyone can share and links? Thanks
