Integrating Filtration and Sealing Technology
FilterSeal™ components are proprietary hybrid devices that integrate elastomeric sealing and filtration functionality into a single unit. These components consist of a custom-engineered composite structure that incorporates elastomers with fabric, metallic, or polymeric filter media. FilterSeal™ technology is designed to meet specific application requirements through a range of elastomer and filter material combinations.
FilterSeal™ Properties
Composite Structure
- Primary components: Elastomer matrix with embedded filter media
- Filter media options: Fabric mesh, metallic screens, polymeric membranes
- Elastomer options: Silicone, fluorocarbon, and other application-specific elastomers
Filtration Capabilities
- Particle size range: Macroparticles to molecular-level filtration (e.g., water vapor)
- Customizable pore size and distribution
- Filtration efficiency dependent on selected mesh/membrane characteristics
Sealing Properties
- Conformable elastomeric profile for effective surface sealing
- Customizable durometer and compression set resistance
- Chemical compatibility tailored to application environment
Advantages of FilterSeal™ Technology
