These products are valued for their stability in temperatures ranging from approximately −60°C to over 200°C.
How Do Silicone Rubber Manufacturers Produce Silicone Rubber?
Silicone rubber manufacturers produce elastomers through controlled chemical and mechanical processes. The basic production workflow includes:
- Polymer synthesis: Silicon metal reacts with methyl chloride to produce silicone intermediates.
- Polymerization: These intermediates form long-chain silicone polymers.
- Compounding: Fillers, catalysts, and stabilizers are added.
- Shaping: Extrusion, molding, or calendaring forms the final product.
- Curing: Heat or chemical curing converts the compound into flexible rubber.
Manufacturers maintain strict quality controls to ensure uniform elasticity, durability, and safety.
What Raw Materials Do Silicone Rubber Manufacturers Use?
Silicone rubber manufacturers rely on several base materials and additives to produce stable elastomers.
| Material | Function |
| Silicon metal | Core element used to create silicone polymers |
| Methyl chloride | Forms silicone intermediates |
| Silica fillers | Improve strength and durability |
| Peroxide or platinum catalysts | Enable curing and crosslinking |
| Stabilizers | Enhance temperature and chemical resistance |
These materials allow manufacturers to produce silicone with different hardness levels and performance characteristics.
