Extruders of silicone rubber tubing and profiles are offered what is said to be unprecedented flexibility and convenience with the new Sil-X-Shin silicone elastomers from Shin-Etsu Silicones of America, Akron, Ohio. These HCR (high-consistency rubber) products in Shore A hardnesses from 30 to 80 all use the same 10:1 mix ratio of base compound to catalyst. What’s more, all six bases use the same “universal” platinum catalyst.
In a conventional 1:1 HCR system, if a customer stocked 1000 lb of each base material, it would need 6000 lb of bases and 6000 lb of catalysts, amounting to 12,000 lb of inventory and a total of 12 different products. With Sil-XShin, the processor would have 6000 of bases and only 600 lb of a single catalyst—that’s 6600 lb of inventory and just seven products. These products are USP Class VI compliant and are designed for healthcare, beverage, and architectural glazing applications.

In failure analysis, there is a tendency to gravitate to a few common test protocols. But this approach can result in a mismatch of techniques to the problem.
