2. By Appearance and Form

• Solid rubber (also known as dry rubber)
• Emulsion rubber (referred to as latex)
• Liquid rubber
• Powder rubber

3. By Performance and Application

• General-purpose synthetic rubber
• Semi-general-purpose synthetic rubber
• Special-purpose synthetic rubber
• Specialty synthetic rubber

4. By Physical Properties

• Hard rubber and soft rubber
• Raw rubber and compounded rubber

Industrial Classification by Function (Heat Resistance, Oil Resistance, etc.)
