Chomerics Division of Parker Hannifin Introduces Corrosion-Resistant Form-In-Place EMI Gasket Material
WOBURN, MA, February 8, 2007 - Chomerics, a division of Parker Hannifin Corporation (NYSE: PH), announced the introduction of CHOFORM® 5550 corrosion-resistant form-in-place gasket material. CHOFORM® 5550 is a one component, thermal cure, electrically conductive material containing nickel-plated graphite particles dispersed in a silicone elastomer. The material is designed for increased flow rates for robotically dispensing onto metal castings. CHOFORM 5550 gaskets provide excellent EMI shielding and demonstrate superior galvanic corrosion resistance when dispensed on bare metal electronics housings, such as base station PCB covers and other electronic equipment requiring long service life under harsh, high-demand conditions.
The gaskets provide shielding effectiveness above 80 dB from 1 to 10 GHz, and are designed to meet UL 94V-0 flammability requirements. The high shielding effectiveness and electrical stability of CHOFORM 5550 material has been validated in severe environments such as urban gas, salt fog, and high temperatures, as well as in high temperature/high humidity cycling. Test data is available on request from Chomerics. CHOFORM 5550 gaskets are robotically dispensed onto customer enclosures or castings and heat-cured at 150C in just 30 minutes, allowing fast handling, quality inspection, and packaging of dispensed parts.
