What mistakes should you avoid?

English speakers often mistakenly use the word 'silicon' (the element) and 'silicone' (the polymer) interchangeably, but in Japanese, both are typically referred to by the single loanword シリコン.

Did you know?

  • To avoid any scientific ambiguity, the Japanese Industrial Standards (JIS) specifically mandate the use of the long vowel version, シリコーン, to denote the polymer.
  • The technical term ケイ素樹脂 literally translates to 'silicon resin', combining the word for the element ケイ素 with 樹脂 meaning 'resin'.
  • In Japan, the term シリコン is frequently used to refer to 'Silicon Valley' as シリコンバレー, even though the region is named after the element 'silicon' and not the polymer 'silicone'.
