Automotive hoses are made from various materials to suit performance requirements:
Basic Materials:
- Synthetic Rubber: Flexible and heat-resistant, often used in cooling and fuel hoses.
- Silicone: Highly heat-resistant (-60 to +260°C), used in high-temperature environments.
- Thermoplastic (such as nylon): Lightweight, flexible, and chemically resistant.
- Reinforcement with steel wire or fibers: In high-pressure hoses to prevent rupture and expansion under pressure.
The general structure of hoses typically consists of:
- Inner Layer: Handles flowing liquids or gases.
- Reinforcement Layer: Steel wire or fabric to increase mechanical resistance.
- Layer External: Protects against external elements and provides added durability.
