The Pros of Silicone Foam
Flame ratings: Carry UL94 V-0 flame ratings.
Low compression set: Featuring a UL50/UL50E compression rating, with less compression set than silicone sponge.
Wide temperature range: Can operate in lower temperatures than silicone sponge. Service temperatures, depending on the specific product, are generally between -60 and 401-degrees Fahrenheit.
Resistance to UV, ozone, and solvents: UL1571, UL1572, UL157 Oil immersion rating
Thermal insulation: Because the material contains more air, it boasts a better thermal insulation than silicone sponge.
Excellent performance: On sealing, cushioning, soundproofing, and other challenging applications.
Silicone Foam Structure
● Open cell foam structure permits excellent absorption of water, moisture, and dust – making it perfect in a conventional sponge used for washing automobiles.
● Closed cell foam structure doesn't accommodate for the absorption of water, moisture, or dust – making it excellent in sealing applications where water and dust need to be kept out. This kind is intrinsically hydrophobic (repels water) (repels water).
Types of Silicone Foam
High-temperature silicone foam:
Suitable for use in high-temperature applications up to 300°C
01
High market share
Designed to provide electrical conductivity for use in EMI shielding and grounding applications
02
Flame-retardant silicone foam:
Formulated to meet various industry flame retardant standards.
03
Closed-cell silicone foam:
With a high compression set and low water absorption, making it ideal for sealing applications
04
Open-cell silicone foam:
With excellent sound absorption properties and low compression set, making it ideal for use in acoustic and vibration damping applications.
05
