Thermoplastic elastomer is made from SEBS, while thermoplastic rubber is made from SBS. [https://www.xometry.com/resources/materials/thermoplastic-rubber-tpr/]. TPR is what we want more for tires [https://www.xometry.com/resources/materials/tpr-vs-tpe/] due to its higher grip.

Thermoplastic olefin. These are typically physical blends of rubber and olefin (such as PE) [1] Check.png. For example, EPDM powder can be mixed with PP and PE, and we have rubber properties with melt processability of polyolefins.
