Common mistake
Be careful not to use this term in formal or professional settings, as the slang meaning is very common and can be considered rude or dismissive. If you are talking about actual materials in a manufacturing or engineering context, it is better to use specific terms like 亞加力膠 or 聚碳酸酯 to avoid ambiguity.
