Asɛm no da compression ratio nhyehyɛe no so. Nhyɛsoɔ a wɔkamfo kyerɛ ma foam silicone rings no taa yɛ 15% ne 30% (ma closed-cell structures). Nanso, sɛnea ɛbɛyɛ a wobenya nsɔano a edi mũ no, wɔyɛɛ groove no mu dɔ sɛ mm 3.8 pɛ, na ɛde nhyɛso ratio ankasa a ɛyɛ (5 – 3.8)/5=24% bae, a ɛda adi wɔ baabi a wɔakyerɛ no mu.
