About Parker Chomerics
The Chomerics division of Parker Hannafin Corporation is a leader in the development of thermal interface and electrically conductive materials. If you’ve spent any time in the medical device, aerospace and defense, or emerging technology industries, you’ve probably heard of them and know their reputation for high-quality, dependable materials.
The Parker Chomerics CHOFORM form-in-place (FIP) gasket materials have proven time and time again that they can meet and exceed expectations for performance. If your application requires durable devices that can survive harsh and hostile conditions, you need a Chomerics gasket that is up to the challenge.
While there are many materials to choose from, CHOFORM 5541 may be a good fit for your device. Read on to learn why.
EMI Shielding Materials and Applications
The CHOFORM materials line has provided reliability in field applications for years, leading the way in high-performing, high-quality materials. As technology advances, devices are shrinking in size and OEMs need materials that check the boxes and fit the bill. There are thousands of EMI shielding materials to choose from, but understanding the needs of the end user creates a set of parameters that cannot be tossed to the wayside.
Depending on your industry, there are a variety of CHOFORM materials that may suit your needs. The ideal material is one where cost and functionality intersect. CHOFORM materials offer a wide selection to choose from, ensuring that there will always be one that checks the boxes and doesn’t blow your budget.
The CHOFORM EMI shielding materials are robotically dispensed which results in a precise gasket bead on metal and plastic housings. (Learn how we’re breaking the boundaries of small bead FIP here!) FIP gaskets made of CHOFORM materials are a great fit for tight spaces and complex geometries, lending themselves to many different applications.
Ease of application is greatly improved with FIP gaskets as they do not require the time spent by someone manually placing them. Beyond that, FIP gaskets reduce waste, compared to die cutting, for example, keeping your bottom line in check.
Features / Benefits of CHOFORM 5541
Choosing the right CHOFORM material can be tricky, especially when it comes to life-saving and life-changing devices. The Parker Chomerics CHOFORM 5541 form-in-place material is a Swiss-army knife of sorts when it comes to EMI gaskets and may be a great fit for your project if you need a reliable “everyday” type of material.
According to the Parker Chomerics website, CHOFORM 5541 is a one-component thermal cure silicone system with >65 dB shielding effectiveness. It has good galvanic corrosion resistance on mated aluminum surfaces and superb adhesion properties. The Ni/Graphite particle filler utilizes a thermal cure technology, rapidly curing at 150℃ for only 30 minutes.
CHOFORM 5541 is CNC dispensed, making it a perfect material choice for quick turn-around prototypes, and allows production to scale effortlessly. It is among the hardest material offered in the CHOFORM product line, with a 75 durometer (Shore A), and because of the lower volume resistivity, for grounding only, the 5541 material is an excellent choice.
With the CHOFORM line of FIP materials, you can expect up to a 60% reduction in installation cost and up to 60% space savings within enclosures. Thanks to these qualities, CHOFORM 5541 is well suited for densely populated electronics packaging, PCB inter-compartmental isolation with thin wall boundaries, and medical device, defense, and telecommunication applications.
Manufactured with Speed and Precision: Selecting the Right FIP Dispensing Partner
When working with premium materials like CHOFORM 5541, the dispensing process is just as critical as the material selection itself. The most advanced EMI shielding material in the world can't perform to specification if it's not properly dispensed with precision and expertise.
Finding the right manufacturing partner for your form-in-place gasket dispensing needs can make the difference between a defense project that fails in the field and one that performs flawlessly under pressure.
Why Partner Selection Matters for FIP Dispensing
FIP gasket dispensing is as much an art as it is a science, with a steep learning curve that can impact your project's timeline and performance. When evaluating potential partners, consider these critical factors:
- Engineering expertise and support throughout the process
- Vertical integration capabilities to reduce lead times and risk
- Quality management systems with defined metrics and goals
- Experience with defense applications and security compliance
At Modus Advanced, we've invested heavily in both the technical capabilities and the engineering talent required to master the FIP dispensing process. With over 10% of our staff being degreed engineers, we provide our defense partners with direct access to technical experts who understand both the materials science and the manufacturing processes required for perfect FIP gasket dispensing.
