Westinghouse nuclear power safety device is diallyl phalate composite. This small ‘I’ beam is extruded 14 ft. long. It is drilled, stand-up rivits are then inserted and electronic parts are wave soldered in place. Thickness of the strip is .063 + or -.001. Assembled device with electronic parts is submerged with radio-active fuel rods and will last the life of the nuclear power reactor. Diallyl phthalate is a very high capability thermoset used in many military high frequency applications.
Bag sealing strip—Alkyd Polyester Composites(sp) — The extruded dovetail was much more accurate(+/- .001″) than the machined silicone laminate. Close or tight tolerances are not a problem. These materials are all U.L. approved.
Excellent for circuit breaker parts. No “fuzz” from cut-off operations which can interfere with assembly and operation. Pulltrusions have problems with their fuzzy cut off ends. Extruded Thermosets don’t have this problem that stop the assembly cells.
25 poles were magnetized around a ring cut from a tube of 80% ferrite loade thermoset. It was then heat steaked to a thermoplastic hub. The application was a low temperature ice maker and there was little or no expansion to the part, which would have affected the close .004 overgap of the motor for a refrigerator application. Close tolerances are not a problem for Extruded Thermoset Composites.
