How to say "silicone" in Japanese

Choosing the right word
  • nounCovers silicone as the synthetic polymer, the material of kitchenware, sealants and medical devices. The fuller transcription of the English word, it unambiguously names the polymer rather than the element silicon.
  • nounAlso a common word for the polymer, especially in everyday talk about silicone goods, but it likewise means silicon, the element, so シリコーン is clearer when the material itself is meant.

Both are common words for silicone, the synthetic polymer; 「シリコーン」 is the fuller transcription and unambiguous, while 「シリコン」, a shortened form that also means the element silicon, works fine in everyday contexts.
