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.
