Ultem® PEI (polyetherimide)
Ultem® PEI is a semi-transparent high temperature plastic. It is used to make custom parts as well as fasteners such as screws, hex nuts, washers, threaded studs and spacers. It can be both molded and machined. Ultem® hardware is also available in glass-filled grades for enhanced strength and stiffness. (Glass-filled grades are opaque.) Ultem® 1000 is the natural grade and Ultem® 2300 is the glass-filled grade.

It is an amorphous plastic.…
Teflon® (PTFE) Fasteners
Teflon® (PTFE) is fabricated into fasteners. These include screws, hex nuts, hex head cap screws, flat washers etc. It is also used to fabricate custom parts. However, this material can only be turned, or made into parts on a CNC machine. It can also be compression molded. But it cannot be injection molded. It is not a thermoplastic.
These fasteners and custom parts are used in applications where high heat and chemical resistance are required. …
Plastic Bag Waste in the Oceans
Over three trillion single use plastic bags are produced every year. Much of them find their way into our oceans. A large majority of these bags are made of polyethlene (PE). Polyethylene is a strong plastic that takes decades to break down. But it may be that the lowly wax worm can offer a solution to this massive problem.
