Versatility is the word that best describes Proteus® Co-Polymer. It is perfect for fire truck tanks because it is inexpensive, easy to fabricate and won’t crack from road vibration. Proteus® Co-polymer also works well in those orthotic devices that require a lower degree of rigidity. It can also be used in a variety of applications requiring chemical resistance and/or FDA compliance.
