Simrit’s Proprietary Materials for Plate Seals
Simriz ® Perfluoroelastomer
Simriz, Simrit’s proprietary family of perfluoroelastomer
compounds, is now available for plate seals. Designed
for thermal stability and nearly universal protection against
chemical attack, Simriz compounds have a high level of
elasticity and offer premier sealing performance. With a
fluorination level of 72%, Simriz FFKM elastomers have
a level of resistance close to that of pure PTFE (76%). At
the same time, FFKM materials exhibit resilience that makes
them an excellent choice for applications where resistance
to aggressive chemicals and tight sealing is required.
Conductive Elastomers
Simrit offers a wide range of conductive elastomers.
Both silicone and fluorosilicone families of electrically
conductive compounds are available specifically for
O-rings and plate seal applications. These plate seals
and O-rings offer shielding for use in electromagnetic
interference (EMI) and radio frequency interference (RFI)
suppression applications. These EMI/RFI compounds are
formulated with silver and silver-plated alloys, offer from
.001 to .05 ohms centimeter resistance, and have excellent
fuel and solvent compatabilities. These sealing materials
are commonly used in aerospace, ship-borne, and
ground-based electronics equipment.

Simrit is the single-source developer of Simriz, starting
with the base polymer, thus ensuring complete oversight
and continuity in the compounding process.
Eliminating any need for costly outsourcing, Simriz
compounds offer the highest seal quality at a highly
competitive price.
