Typical porous material is carbon graphite, carbon, or silicon carbide, familiar materials with proven track records for seals. Due to construction methods, a porous material seal in a metal holder, will operate up to about 300 degrees Fahrenheit. Input pressure to the porous material is typically 60-100 psi, but can be higher, based on the specific need (e.g., for sealing against high opposing pressures). These materials have high heat capability, since they are typically sintered when manufactured; they can typically resist oxidation to at least 600 C without melting (like babbitt), or without burning (like polymers).
The porous material for New-Seal can also be made in ceramic matrix composites. Custom materials can be made to accommodate higher temperatures, and more extreme conditions.
Call us to discuss your specific application, and New-Seal will provide the correct material option for your need.
Our CMC materials are similar to those used
for race car braking applications, and can be
used for high temperature applications.
