    Material scientists call Santoprene rubber a ”TPE/TPV”, a Thermo-Plastic Elastomer/Thermo-Plastic Vulcanizate. More specifically and uniquely, Santoprene rubber is a thermoplastic material. Developed by Monsanto, Santoprene rubber is the product of Advanced Elastomer Systems, which is now a part of ExxonMobil, the world’s largest supplier of polypropylene and EPDM rubber. All types of traditional rubber are thermosets. Thermosets (such as in rubber) are heated and then cured, meaning that they become molecularly cross-linked. Thermosets do not “melt-down” after cross-

    linking, instead they burn.
    Thermoplastic Elastomer (TPE): a diverse family of rubber-like materials that, unlike conventional vulcanized rubbers, can be processed and recycled like thermoplastic materials.
    Dynamic Vulcanization: the process of intimate melt mixing a thermoplastic polymer and a suitable reactive rubbery polymer to generate a TPE with a chemically crosslinked rubbery phase, resulting in properties closer to those of a thermoset rubber when compared to the same uncrosslinked composition.
    Thermoplastic Vulcanizate (TPV): a TPE with a chemically crosslinked rubbery phase, produced by dynamic vulcanization.
    TPEs provide functional performance and properties similar to conventional thermoset rubber products, but can be processed with the speed, efficiency and economy of thermoplastics.
    In addition to simpler processing, principal advantages of TPEs compared to thermoset rubber products include easier recycling of scrap and closer, more economical control of dimensions and product quality.
    TPEs are used in a variety of applications in the loudspeaker, automotive, construction, medical, food and beverage, electrical, appliance and consumer electronic markets.
