Stiff material with low thermal conductivity

Ultem, or PEEK for your requirements.In summary, the conversation is about finding a material with high stiffness, low thermal conductivity, temperature resistance up to 150°C, no low friction coefficient, good fracture behaviour, and affordability. Suggestions were made for a polymer-matrix/carbon-fiber composite and engineering resins such as Delrin, Ultem, and PEEK from SABIC Innovative Plastics.

Hi,

i'm searching for a material with the following properties:

- high stiffness
- low thermal conductivity
- temperature resistance up to 150°C (not getting too soft at 150°C)
- no low friction coefficient (so no PTFE)
- good fracture behaviour (so no glass, ceramic)
- cheap

I've found some materials, but each of them doesn't meet at least one condition.

Does anyone know such a material?

A polymer-matrix/carbon-fiber composite would probably suit your needs.

check with SABIC Innovative Plastics, this website

http://www.sabic-ip.com/gep/en/Home/Home/home.html

they have many different engineering resins. Dig a little from this website page, you can search for properties and maybe find just what you need.

I would recommend looking into materials such as carbon fiber reinforced polymers or composites, which have high stiffness and low thermal conductivity. They also have good temperature resistance and can withstand temperatures up to 150°C without getting too soft. Additionally, they are relatively inexpensive compared to materials like glass or ceramic. However, it is important to note that these materials may still have some friction coefficient, but it can be reduced by using lubricants or coatings. It would be best to conduct further research and testing to determine the most suitable material for your specific needs.
 

What is a stiff material with low thermal conductivity?

A stiff material with low thermal conductivity is a material that is resistant to bending or deformation and also has a low ability to transfer heat. This means it is difficult to bend or break, and it does not allow heat to pass through it easily.

What are some examples of stiff materials with low thermal conductivity?

Some examples of stiff materials with low thermal conductivity include ceramics, diamond, graphite, and some metals such as stainless steel and titanium.

What are the benefits of using stiff materials with low thermal conductivity?

The benefits of using stiff materials with low thermal conductivity include increased strength and durability, as well as improved insulation properties. This makes them useful in applications where high temperatures or thermal insulation are important.

Are there any limitations to using stiff materials with low thermal conductivity?

Yes, there are some limitations to using stiff materials with low thermal conductivity. These materials can be brittle and may not be suitable for applications where flexibility or shock resistance is needed. They can also be expensive and difficult to shape or process.

How are stiff materials with low thermal conductivity used in scientific research?

Stiff materials with low thermal conductivity are commonly used in scientific research for applications such as insulation, thermal barriers, and heat sinks. They are also used in experiments to study heat transfer and thermal conductivity properties of materials.
