Supplier's Category: All Foams & Insulation: Thermal barriers, acoustic foams, and EMI shielding
Foams and insulation materials — thermal barriers, acoustic foams, EMI shielding — manage heat, sound, or electromagnetic interference within an assembly. They’re specified by density, compression set, and the specific performance property (thermal, acoustic, or EMI) needed.
These materials often get treated as an afterthought in design, when in fact compression set and long-term performance vary significantly by formulation.
- Confirm compression set rating if the foam will stay compressed in an assembly long-term
- Check flammability rating (UL94, FMVSS) against your industry’s requirements
- Verify the material is actually rated for the specific property you need (thermal vs. acoustic vs. EMI), since foams specialize
Related terms: thermal insulation foam, acoustic damping foam, EMI shielding gasket, compression set rating, flammability rating (UL94), closed-cell vs. open-cell foam, conductive foam for EMI
Where each foam type is used
Foam selection maps closely to which single performance property the assembly actually needs.
- Enclosures and electronics: EMI shielding gaskets and conductive foam
- HVAC and appliances: thermal insulation foam for energy efficiency
- Automotive and consumer products: acoustic foam for noise damping
