Orange Silicone Custom-Shaped Gasket
Orange silicone custom-shaped gaskets are precision-engineered sealing components designed to meet specific application requirements in industrial, automotive, food, and medical systems. Their vibrant orange color not only provides easy identification but also indicates high temperature resistance, chemical stability, and food-grade safety where applicable.
1. Key Features & Functions
- Custom design to fit complex or irregular sealing surfaces
- High elasticity and compression recovery to maintain leak-proof performance
- Resistant to heat, UV, ozone, and many chemicals
- Vibrant color aids in visual inspection and identification
Engineering Insight: Custom-shaped silicone gaskets are ideal for applications requiring tight tolerance sealing in irregular geometries, ensuring long-term reliability and minimal maintenance.
2. Material Properties
| Material | Temperature Range | Key Features | Typical Applications |
|---|---|---|---|
| VMQ (Silicone) | -60°C to +200°C | High elasticity, excellent thermal and chemical resistance | Food processing, medical devices, automotive sealing |
| FDA / Food-Grade Silicone | -60°C to +200°C | Non-toxic, compliant with FDA and EU standards | Pharmaceutical equipment, beverage dispensers |
| High-Temperature Silicone | -50°C to +250°C | Superior heat resistance, long-term compression set retention | Industrial ovens, HVAC systems, high-temp valves |
Material Selection Tip: Use food-grade silicone for applications involving consumable products, and high-temp silicone for thermal-critical industrial environments.
