Chomerics Europe - a division of Parker Hannifin - has introduced a new one component, form-in-place (FIP) EMI gasketing material. CHO-FORM 5547 is designed for use in applications such as portable equipment, telecoms, and military and marine products. With a hardness of 48 (±5) shore A, CHO-FORM 5547 is especially useful in applications where assembly closure forces are low and can eliminate the need for fasteners or rigid housings.

The material utilises nickel-plated silver (Ni/Ag) particles dispersed in a silicone binder to deliver shielding performance of greater than 70 dB (200 MHz to 10 GHz). The material can be placed on narrow housing flanges using the latest FIP dispensing technology. Corrosion resistance and good long-term stability are important benefits offered by the solvent (VOC) free material.

CHO-FORM 5547 is supplied in a choice of 30cc or 55cc syringes that support rapid prototyping or a 300cc cartridge. It is suitable for use in applications with operating temperature ranges from -50°C to +130°C.
