I Need good HVAC tape for OUTSIDE that withstand hot/cold weather

I have two compressors with 6 airheads total. They were installed on my flat roof aboI have two compressors with 6 airheads. They were installed on my flat roof about years ago. All works, and although I had most of the copper wires encased (and rubberized with Armaflex), some had to be wrapped by Armaflex and HVAC tape only. I bought what I thought was the best possible tape at Home Depot (but to be fair, it did not have foil).

Unfortunately, since I live in the Queens, we get anything from 0F to 100F (and snow too). The HVAC tape dried out within a year, year & half.

My question: What kind or brand of HVAC do I need to get that will last me longer. I heard that it should contain foil for extra re-enforcement.

Thank you all for the advice.

Below are two photos to show you an example of the turns that I need to wrap (taken when I initially installed the HVAC tape)
