He 0.12 a hiki i ka 0.25[W/(m·K)] ka thermal conductivity o ka rubber silicone, ʻo ia hoʻi he 23 manawa ma mua o ka lāʻau synthetic maʻamau.
Ma ka hoʻopiha ʻana i ka nui o nā mea hoʻopihapiha hoʻopihapiha wela, hiki ke hana ʻia nā huahana hoʻoheheʻe wela me ka 0.4 a i ka 2W/(m·K). Eia kekahi, ʻoi aku ka kiʻekiʻe o kona coefficient o ka hoʻonui ʻana i ka leo, ma kahi o 6 a 8 × 10 ⁻ ⁴ ⁻ ¹, ʻo ia ka mea like me 2 a 2.5 mau manawa o ka lāʻau synthetic maʻamau.
