1. Molecular Mastery: Silicone vs Silicon 

While **silicon** (Si) is a natural element found in quartz, **silicone rubber** is a synthetic polymer with a Si-O backbone bonded to organic groups. This unique structure delivers:  

- **Thermal Stability**: 305°C continuous operation (UL 94 V-0 certified)  

- **Chemical Inertness**: pH 0-14 resistance (ASTM D471 tested)  

- **Flexibility Retention**: -70°C to 250°C functional range  

2. Engineering Advantages of Yutian Silicone  

**2.1 Extreme Temperature Performance**  

| Application          | Temperature Range | Certification       |  

|----------------------|--------------------|----------------------|  

| EV Battery Seals      | -50°C to 200°C     | UN ECE R100          |  

| Medical Autoclaves    | 135°C (steam)      | ISO 10993-5          |  

| Aerospace Gaskets     | -70°C to 305°C     | MIL-STD-810G         |  

**Case Study**: Reduced thermal degradation by 73% for a solar panel sealing project in Dubai.  

**2.2 Sterilization & Safety**  

- **Medical Grade**: USP Class VI, EU Pharmacopeia 5.1.9
