Development of o-ring substitute in Antenna Casing

  • O-ring substitute project requirements
    1. Part must withstand IP67 (dust and water international protection rating)
    2. Part must be conformable for sealing purposes, but not crushing so not to breach IP67
    3. Part must withstand harsh environments
    4. Part must be easy to handle for assembly
    Our solution
    1. We specified a closed cell foam and 3M adhesive tape 9088, which we laminated onto both sides of the foam. Both materials were suitable for extreme environmental conditions
    2. Based on customer drawings, we provided several rounds of samples to support environmental testing
    3. Final production parts were supplied as single pieces, with easy peel tabs to aid application
