The perfect solution to thermal insulation : PEEK and polyimide

The heat shield, which exists like a protective suit, guards the equipment from high temperatures. It is available in a wide variety of materials, including polyester, fiberglass, paper or other polymers, and even engineered polymers such as PEEK and PI plastics. The characteristics of these materials vary, but they are all designed to meet our insulation needs in a variety of environments.

Heat shield is used on the surface of the equipment with different thickness and heat-resistant cap, used to prevent high temperature. It is usually made of polyester, fiberglass, paper or other polymer materials, commonly used engineering plastics are PI plastic and PEEK plastic, the most important is the characteristics of high thermal stability, why the use of PI plastic so popular?

Why choose PEEK plastic?

PEEK is an engineering plastic whose excellent properties are demonstrated in a wide range of temperature and chemical resistance applications. Whether it's the extremely high maximum permissible temperatures, excellent resistance to corrosive media, or the ability to be used in the presence of water, PEEK demonstrates its versatility and excellence. Whether in sheets, rods or tubes, PEEK is available in the best possible form.

The benefits of choosing PI Polyimide are obvious:

PI as a highly engineered polymer provides optimum performance in a wide range of temperature and chemical resistance applications. The material has a high maximum permissible temperature, it is very strong and has a high melting point of around 300 degrees Celsius. In addition to this, it can be produced in a wide range of colors and is resistant to most chemicals such as acids and bases. Generally, polyimide is thermally stable, does not lose mechanical properties when heated, has excellent resistance to aggressive media and can be used in the presence of water.PI materials can be supplied in various forms, such as rods, bars or tubes. However, for this application, PI plastic rods are typically used.

The following benefits can be gained by using PI plastics in insulating shrouds:

1. PI is one of the highest temperature resistant plastics available.

2. PI has excellent resistance to a wide range of acids, bases, and solvents.

3. PI performs well at high temperatures, with maximum continuous operating temperature ratings up to 482°F (250°C)

4. PI has excellent mechanical properties and low moisture absorption (0.6% over 24 hours) even at elevated temperatures.

5. PI is FDA-approved for food contact and medical device applications, so PI can be used wherever food or therapeutic grades are required.

6. PI materials do not soften or flow at high temperatures.

7. PI materials have minimal outgassing properties.

As excellent materials for heat shields, both PEEK and polyimide have their own advantages, they both have good flexibility and durability and are reasonably priced, either material offers the perfect solution for our insulation needs. With some research, educated buyers are sure to find the best polyimide or PEEK shield for their needs.
