PEI (polyetherimide) compounds start from the base resin, amorphous polyetherimide, which is an amber-to-transparent thermoplastic with characteristics similar to the related, much more costly plastic PEEK.
Our PEI compounds are inherently flame resistant and provide a high resistance to elevated temperatures and solvents. Compounds within the AuroraGuard™ PEI family are produced by Enviroplas, an Aurora Plastics company. They provide high mechanical property performance in continuous use environments to 340°F (170°C). Their toughness and rigidity can be further enhanced with fiberglass reinforcement.
