Thermoplastic olefin. These are typically physical blends of rubber and olefin (such as PE) [1] 
. For example, EPDM powder can be mixed with PP and PE, and we have rubber properties with melt processability of polyolefins.
See 2.5.1 - on C-TPO - conventional - or physical blend [2]
Rubber Types
Here is a tree of all rubber types [3]
TPE vs TPR
- Thermoplastic elastomer is made from SEBS, while thermoplastic rubber is made from SBS. [4]. TPR is what we want more for tires [5] due to its higher grip.
- TPS is one of the Thermoplastic Styrenes, either SBS or SEBS.
- It appears TPR=TPS=Thermoplastic Rubber=Thermoplastic Styrenes
