AKRON—Shin-Etsu Silicones of America Inc. has launched its newest high consistency rubber line, Sil-X-Shin Silicone Elastomers.
The platinum, addition-cure series includes two distinct HCR extrusion versions: methyl vinyl and phenyl silicone, specifically engineered for extruded tubing and profiles, and designed for use in healthcare, beverage and architectural glazing applications.
Both series are available in a range of Shore A Hardness from 40 to 80, and come in a 10:1 ratio of base compound to catalyst.
"We have intentionally engineered the formulations to have a longer working time between milling and extrusion," said Steve Craig, national business manager for Shin-Etsu Silicones of America. "This increases material scheduling flexibility, as the product can actually be staged for nearly 24 hours during the processing gap."
The methyl vinyl extrusion grade features translucence and clarity, according to the statement, with extruded tubing exhibiting no bubble formation while curing in the oven.
The phenyl silicone extrusion grade works in temperatures lower than -40° C, with a -60° C minimum for optimal usage. It is suited for applications such as pharmaceutical process tubing requiring low temperature resistance.
