PHILADELPHIA, PA — Stockwell Elastomerics announced it now offers a general-purpose, specification-grade solid silicone. This solid silicone sheeting is made in the USA and available in 5 different durometers from 30A to 70A with thicknesses from 0.020” to 0.500”. This sheet silicone comes standard in red, but black and gray sheets are available upon request. The HCR (High Consistency Rubber) based, spec grade, general purpose silicone is formulated to meet A-A-59588 2A/2B, (formerly ZZ-R-765 2A/2B), ASTM D2000, AMS 3301, AMS 3302, AMS 3303, and AMS 3304 specifications. For ease of assembly, Stockwell Elastomerics can apply acrylic or silicone adhesive (with a release liner) to one or both sides.
The addition of this spec-grade silicone to the company’s already considerable inventory underscores Stockwell Elastomerics declared its commitment to maintaining industry-leading stocking levels. As supply chain issues clear for many different classes of materials, buyers can find what they need and choose value-added services such as the application of an adhesive backing. Sample swatches and prototype parts using this solid silicone are available.
The following designations are now available, with key specification data shown:
SG-30 GP: 30 Durometer Shore A, 725 psi tensile strength, 750% elongation, 75 tear (ppi die “B”)
SG-40 GP: 40 Durometer Shore A, 800 psi tensile strength, 700% elongation, 110 tear (ppi die “B”)
SG-50 GP: 50 Durometer Shore A, 850 psi tensile strength, 550% elongation, 125 tear (ppi die “B”)
SG-60 GP: 60 Durometer Shore A, 800 psi tensile strength, 500% elongation, 150 tear (ppi die “B”)
SG-70 GP: 70 Durometer Shore A, 800 psi tensile strength, 325% elongation, 130 tear (ppi die “B”)
More technical details are available in the SG Series technical data sheet found on the solid silicone data sheets web page.
“This new SG Series solid silicone is a versatile, specification grade, general purpose material for applications in extreme environments, especially where high temperatures are involved,” said Dan Shanahan, Director of Application Engineering.
