1. Ultra Technical Product Definition
The Silicone Rubber Ball (SIR) is a crosslinked elastomeric sphere made from high-grade silicone polymer chains (–Si–O–Si– backbone structure), engineered for:
- Extreme temperature resistance
- High elasticity retention
- Non-toxic hygienic performance
- Long-term aging stability
- Mechanical vibration damping
Unlike conventional rubber (NR, NBR, EPDM), silicone offers a more stable molecular structure, making it suitable for critical thermal and hygienic environments.
2. Advanced Material Science (Silicone Polymer System)
2.1 Silicone Molecular Structure Advantage
- Backbone: Siloxane (Si–O–Si) bonds
- High bond energy → superior thermal stability
- Flexible molecular chain → excellent elasticity
- Low surface energy → non-stick properties
Engineering Result:
- Does not easily crack under heat
- Maintains softness in cold conditions
- Resistant to oxidation and UV breakdown
2.2 Curing System Technology
- Peroxide curing system (standard industrial silicone)
- Platinum-catalyzed curing (food & medical grade)
- Controlled crosslink density for:
- Compression resistance
- Elastic recovery
- Mechanical durability
2.3 Temperature Engineering Performance
- Continuous operating range: -50°C to +260°C
- Short-term peak resistance: above 260°C
- No hardening at low temperatures
- No melting or deformation at high temperatures
