Stockwell Elastomerics Inc. has launched its EMI gasket materials touch brochure that highlights nickel-plated graphite filled elastomer products.
The touch brochure includes tactile buttons of three different electrically conductive elastomers, the company claimed, and has been created to assist engineers tasked with specifying EMI / environmental sealing gaskets. The EMI Gasket Materials Touch Brochure can be requested online by clicking here.
Stockwell Elastomerics' EMI touch brochure highlights three nickel-plated graphite filled elastomer options:
• SNE-540 is a 40 durometer nickel-plated graphite filled silicone rubber that provides a balance of high shielding attenuation (greater than 100 dB from 20MHz to 10GHz) and compressibility for effective environmental sealing. SNE-540 is readily available in sheets with a thickness range from .020 inch to .125 inch and fabricated into gaskets. Additionally, SNE-540 also can be compression molded into custom gaskets or EMI components.
• SNEF-50 is a 50 durometer nickel-plated graphite filled fluorosilicone elastomer for EMI gasket applications requiring chemical resistance. Fluorosilicone resists swelling in oil and fuel contact, and is rated better than silicone rubber for NBC requirements, according to the company. Stockwell Elastomerics said this compound may be molded into custom configurations.
• SNE-553 is a 30 durometer nickel-plated graphite filled soft silicone rubber with moderate shielding effectiveness. The low durometer is beneficial for applications with limited closure force such as EMI touch screen gaskets requiring environmental sealing and moderate EMI shielding, the company claimed.
