It is a rigid thermoplastic polyurethane and is used to make fasteners such as hex head cap screws, flanged hex head cap screws and hex nuts as well as many custom products. The color of the natural material is off-white. It is also commonly dyed dark gray. It is one of the strongest plastic materials available. Isoplast® 40% long glass TPU has replaced steel in some applications. … Read more
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® PEI Properties:
It is an amorphous plastic. Therefore it has a molecular structure that lacks a continuous repeating form.
Ultem® PEI has no definite melting point. … Read more

Worldwide Shortage of Nylon 6/6
Currently, there is a shortage of nylon 6/6 worldwide. This is because there is a shortage of the key precursor adriponitrile or ADN. Nylon 6/6 is used extensively to make automotive parts, as well as cable ties, power tools, nylons, fabric, fasteners and is used in numerous industrial applications. Nylon 6/6 provides the best mix of process-ability, performance and value for the price for these applications.
