Drops & Non-Certified Materials
If you are currently in the prototype phase of your project and not sure what material should be selected or stage that material certification is not required. Let PlaSteel recycle program benefit you. PlaSteel 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. This quarter featured material: 
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.
