High performance plastics have a permanent operating temperature of more than 250°C. It is this material class that brings the superior properties of polymers – such as abrasion resistance and remarkable corrosion resistance. Thus they stand in contrast to engineering plastics, covering a wide range of functions. Some of their diverse applications include: fluid flow tubing, electrical wire insulators, semiconductor etch process, and fiber optics.

Nickel has been used in alloys that date back to the dawn of civilization. Chemical analysis of artifacts has shown that weapons, tools, and coins contain nickel in varying amounts. Super Alloy is an alloy that exhibits several key characteristics: excellent mechanical strength, resistance to thermal creep deformation, good surface stability, and resistance to corrosion or oxidation.

The use of a vented screw in vacuum environments is critical. A blind tapped hole creates a gas pocket that shows itself as a virtual leak, causing unwanted downtime. The use of a vent or vented screw that has a center-bore provides an outgas path. Trapped gas molecules vent into the vacuum system through the vented screw bolt-head and out of the system.
