Flexible-mount coolant shields are typically made from materials that offer a combination of flexibility, durability, and resistance to coolant fluids. Common materials include:
1. **Polyurethane**: Known for its excellent abrasion resistance and flexibility, polyurethane is often used in coolant shields. It can withstand exposure to oils and coolants without degrading, making it ideal for environments where chemical resistance is crucial.
2. **Polyethylene**: This material is lightweight and offers good chemical resistance. High-density polyethylene (HDPE) is particularly favored for its toughness and ability to withstand impact, making it suitable for flexible-mount applications.
3. **PVC (Polyvinyl Chloride)**: PVC is another popular choice due to its flexibility and resistance to a wide range of chemicals, including coolants. It can be easily molded into various shapes, which is beneficial for creating custom shield designs.
4. **Rubber**: Natural and synthetic rubbers, such as neoprene or nitrile, are used for their flexibility and excellent resistance to oils and coolants. They provide a good seal and can absorb vibrations, which is advantageous in dynamic environments.
5. **Silicone**: Silicone offers high-temperature resistance and flexibility, making it suitable for applications where the coolant shield might be exposed to heat. It also provides good chemical resistance.
6. **Thermoplastic Elastomers (TPE)**: TPEs combine the properties of rubber and plastic, offering flexibility, durability, and resistance to coolants. They are easy to process and can be customized for specific applications.
These materials are selected based on the specific requirements of the application, such as the type of coolant used, the operating environment, and the desired flexibility and durability of the shield.
