Types of Thermoplastic Elastomers
- TPE materials are categorized into thermoplastic olefin (TPO), thermoplastic natural rubber (TPNR), thermoplastic vulcanizate (TPV), thermoplastic polyurethane (TPU), styrene block copolymer (SBC), polyether block amide (PEBA), and copolyester (COPE) - [1]. This is a study of recycling rubber powder with plastics to make rubbery plastics.
- Thermoplastic natural rubber (TPNR) - Rubber blends with plastic - [2]. Thermoplastic is better as it is recyclable. Thermoplastic natural rubber is a blend of natural rubber and thermoplastic. All kinds of mixes of rubbers with thermoplastics are possible - providing the advatages of both materials in one. Toughness and flex of rubbers, with thermoplasticity (recyclability) of thermoplastics.
- Thermoplastic vulcanizate - mix of EPDM in popypropylene - [3]
- Thermoplastic olefins - thermoplastic, filler, thermoset rubber blends.
- Copolyester - once again, blend of rubber and polyster. Hytrel is an example - gasket or seal material. [4]
- Styrene block copolymer - ex. Kraton - [5]
- PEBA - [6]. Good for catheters.

- Natural thermoplastic - gutta-percha - [7]
- Latex - in rubber tree or dandelion root; many plants have latex, only some have rubber latex. Guayule, dandelion have been used commercially - [8]. See more plants - [9]
Notes on Tires
- Air free tires - Bridgestone - [10]
- Recycled rubber can be mixed with thermoplastics or TPEs to extend the thermoplastic by giving it more rubber properties.
- Flat-free bike tires from TPE - [11] & [12]
- TPU tire - [13]
- TPE made from HDPE and ground tires with compatibilizer - [14]
Terms
- Copolymer - [15]
