• A. extrusion
• B. mastication
• C. calendering
• D. vulcanisation

Hint:

Answer 1

The Correct Option is C

Step 1: Understanding the calendering process.
Calendering is the process of converting rubber into a thin sheet or coating it onto fabric by passing the rubber between rollers. This is commonly used in the production of rubber sheets, films, and coatings.

Step 2: Explanation of options.
- (C) Calendering is the correct process for converting rubber into sheets or coating it onto fabric. - (A) Extrusion is used to form rubber into shapes or profiles. - (B) Mastication is the process of breaking down rubber to make it easier to process. - (D) Vulcanisation is the process of cross-linking rubber to improve its properties.

Final Answer: \[ \boxed{\text{C) calendering}} \]
