What is the difference between liquid silicone and solid silicone?

Liquid silicone and solid silicone are the two most commonly used materials in silicone product manufacturing. They differ in physical form, molding process, and performance characteristics.

1. Physical Form

- Liquid silicone: Comes as a flowing liquid in two components (A and B), which cure after mixing

- Solid silicone: Comes as pre-mixed solid rubber compound, requires heating and compression molding

2. Molding Process

- Liquid silicone: Uses injection molding, high automation, high production efficiency

- Solid silicone: Uses compression molding, requires manual material feeding, lower automation

3. Flowability

- Liquid silicone: Excellent flowability, can form complex structures and thin-wall products

- Solid silicone: Poorer flowability, requires higher pressure to fill the mold cavity

4. Performance Differences

- Liquid silicone: Better transparency, excellent rebound performance, high product precision
