EXPANDED GRAPHITE YARN
Description
SunPass SEALING Expanded Graphite Yarn 5000Y is twisted and treated by special process and treatment. During the process, the graphite is reinforced with threads of cotton or other materials. Expanded graphite yarn is suitable for sealing under different media, circumstances, temperature, and pressure.
Application
1. In the field of fire prevention materials, this product is often used to create passive fireproof products such as fire-proof doors, fire windows and firewalls, which can effectively prevent the spread of fire.
2. This product also has a wide range of application in electromagnetic shielding and thermal conductivity, which can be used to manufacture electronic components such as electromagnetic shielding, heating pads and heat dissipation pieces.
3. In the field of sealing materials, this product can be used to manufacture high -performance sealing circles, sealing pads and O -type circles.
Advantages
1.Excellent thermal stability
2.Self-lubricating and has a low coefficient of friction
3.Chemically inert
4.Excellent Insulating Properties
