Chomerics: Pioneers in EMI Shielding
Chomerics, a division of Parker Hannifin, is a global leader in the development and manufacturing of thermal interface and electrically conductive materials. With a history spanning several decades, Chomerics has been at the forefront of innovation, continuously pushing the boundaries of what is possible in EMI shielding technology.
Their FIP gasket materials are designed to protect sensitive electronic components from electromagnetic interference, radio-frequency interference, and environmental factors that could compromise their performance.
Introducing CHOFORM 5538
CHOFORM 5538 is a single-component, moisture cure silicone system that is capable of small-bead size applications while providing >65dB shielding effectiveness. It can be dispensed in the smallest bead size of any Chomerics FIP material, with bead size dimensions of 0.015 x 0.020 inches. It also provides good galvanic corrosion resistance with mated aluminum surfaces. It is a highly versatile EMI shielding gasket material from Chomerics.
This material is designed to meet the stringent demands of modern electronic applications. CHOFORM 5538 is made up of a Ni/Graphite particle filler that uses moisture cure technology. It requires ONLY 4 hours at 50% relative humidity for complete cure.
Additionally, its unique formulation ensures it maintains a strong environmental seal, making it ideal for both EMI containment and environmental protection.
Features / Benefits of CHOFORM 5538
Choosing the right CHOFORM material can be a tricky decision, especially when it comes to life-saving and life-changing devices. These devices need to perform every single time they’re expected to.
CHOFORM 5538 offers many benefits that may suit your project's needs, including:
High Conductivity: The CHOFORM 5538 gasket material's inherent electrical conductivity ensures efficient dissipation of electromagnetic interference, providing optimal shielding effectiveness for sensitive electronic components.
Flexibility and Compression Set Resistance: Electronic devices are no strangers to dynamic environments. CHOFORM 5538 retains its flexibility even after prolonged use, allowing it to maintain a reliable seal against environmental elements. Its resistance to compression ensures that it does not permanently deform under pressure, guaranteeing consistent performance over time.
Broad Temperature Range: From sweltering hot to freezing cold, this gasket material exhibits stable performance over a wide temperature range, making it suitable for applications in diverse environments.
Corrosion Resistance: CHOFORM 5538 is engineered to resist corrosion caused by various environmental factors, ensuring the longevity and reliability of the electronic devices it protects.
Ease of Installation: As a robotically dispensed material, it is a preferred choice for engineers, saving time and effort during assembly. With the CHOFORM family of products, up to a 60% reduction in installation cost can be seen. It’s also great for quick turnarounds and offers up to 60% space savings within enclosures.
