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.

More

  • 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]

Sourcing

  • TPO - $300 for 500 sf - [15]. Comparable price to thinner EPDM at Menards - [16]
