Insulating Gasket FAQ
Q: What is the maximum temperature an insulating gasket can withstand?
A: Our standard insulating gaskets can continuously operate at temperatures up to 250°C (482°F). For higher temperature applications, we offer specialty grades rated for 300°C (572°F). The exact temperature rating depends on the specific material composition and thickness of the gasket.
Q: How do I select the right thickness for an insulating gasket?
A: The appropriate insulating gasket thickness depends on several factors: required dielectric strength (thicker gaskets provide higher voltage insulation), compression requirements, and gap filling needs. As a general rule, we recommend 1mm thickness for every 1kV of insulation required, plus safety margins. Our engineering team can help determine the optimal thickness for your application.
Q: Can insulating gaskets be customized for specific applications?
A: Yes, we offer complete customization of insulating gasket products. We can modify material composition, thickness, shape, and size to meet specific performance requirements. Common customizations include special cutouts, adhesive backing, reinforced edges, or hybrid materials combining different insulation properties.
