Parker Chomerics CHO-FORM® family of conductive form-in-place gasket materials are ideal for densely populated electronics packaging, especially where intercompartmental isolation is required. The form-in-place characteristics mean that CHO-FORM® can be used in rapid prototyping applications on substrates such as castings, machined metal, conductive plastic housings, and at board level.
Parker Chomerics CHO-FORM® 5528 form-in-place EMI gasket is a one-component, moisture cure silicone system with greater than 70 dB shielding effectiveness while providing a soft, low closure force gasket. CHO-FORM® 5528 consists of a Ag/Cu particle filler and utilizes a moisture technology which requires 24 hours at 50% relative humidity for full cure.
Features and Benefits:
• Up to 60% reduced installation cost and nominal cost for production scale-up
• Up to 60% space savings within enclosures (gasketing available for flanges as narrow as 0.025 in)
• Excellent adhesion to common housing substrates (4-12 N/cm adhesion)
• Highly compressible gaskets, ideal for low closure force housings
• Quick turn-around of prototypes and samples
