Drops & Non-Certified Materials

If you are currently in a prototype phase of your project and not sure what material should be selected or stage that material certification is not required. Let Plastic Engineering recycle program benefit you. Plastic Engineering routinely works with drops from high performance plastics that enter into our recycle “green” initiatives. Let us assist in cost reductions by supplying a non-certified material. We typically see a 35%-50% reduction in price.

Ultem 1000 Technical Property Data

Ultem* l000 polyetherimide is an amorphous, high-performance polymer with exceptional flame and heat resistance. It performs continuously to 340°F (171°C), making it ideal for high strength/high heat applications, and those requiring consistent dielectric properties over a wide frequency range. It is hydrolysis resistant, highly resistant to acidic solutions and capable of withstanding multiple autoclaving cycles.

Ultem 100 is FDA and USP Class VI compliant. FDA compliant colors of Ultem are also available on a custom basis. Ultem commonly is machined into parts for reusable medical devices, analytical instrumentation, electrical/electronic insulators and a variety of structural components requiring high strength and rigidity at elevated temperatures.
