# Industrial Specification: Gasket Body

## 1. Technical Definition
The main structural element of a high-precision silicone gasket that provides sealing functionality and maintains dimensional stability under compression.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-15 MPa compression pressure, -60°C to 230°C temperature range**. Failure boundary: **Compression set exceeding 25% at 70°C for 22 hours per ASTM D395, tensile strength below 7 MPa per ASTM D412**, Mechanism: **Siloxane polymer chain scission due to thermal-oxidative degradation above 200°C, leading to loss of crosslink density and permanent deformation**.

### 2.1 Analytical Physics Model
Governed by the **Hansen Solubility Distance (HSP)**:

> **Primary Equation**: $R_a = \sqrt{4\Delta\delta_d^2 + \Delta\delta_p^2 + \Delta\delta_h^2}$  
> **Engineering Impact**: Predicts seal/gasket swelling when exposed to CIP chemicals.
