Understanding CHOFORM 5526

Technology today is shrinking. It's no surprise that devices are becoming smaller, more powerful, and more densely packaged with many components. But with this advance in technology, unique challenges arise, especially when it comes to EMI shielding. Inner compartmental isolation is often required to ensure the smooth and reliable operation of these devices, which can be achieved thanks to materials such as CHOFORM 5526. 

CHOFORM 5526 is a one-component moisture cure silicone system. It provides superior EMI shielding effectiveness. With shielding effectiveness exceeding 100 decibels, it sets a high standard for EMI protection. It's a soft, low-closure force gasket, making it ideal for densely populated electronics packaging where precision and reliability are non-negotiable. 

This material is incredibly versatile and suitable for rapid prototyping. It requires a full cure cycle of 24 hours at 50% relative humidity. CHOFORM 5526 comprises pure silver particle filler, giving it the best shielding effectiveness among Chomerics’ form-in-place materials.
