How it's used

Refers specifically to the raw, gummy, or crepe-like rubber material often used in cleaning tools or shoe soles. It is distinct from synthetic rubber or plastic erasers because of its tacky, soft texture. You will most frequently encounter this term when discussing specialized cleaning supplies for suede or nubuck leather.

rubber eraser for cleaning
crepe rubber sole

Common mistake

Do not confuse this with 擦膠, which is the standard term for a pencil eraser used in school. 生膠 is strictly for the material itself or tools made from that specific raw rubber texture.
