Introduction

Silicone sponge rubber sheets from Rogers ARLON are an excellent solution for thermal insulation applications. These lightweight and flexible sponges provide superior insulation while resisting extremely high and low temperatures. Keep reading to learn more about using ARLON silicone sponges for insulation.

Key Features

ARLON silicone sponges have the following key features that make them ideal for insulation:

Thermal Resistance

ARLON sponges have a very low thermal conductivity, allowing them to resist heat transfer. The table below shows the thermal resistance (R-value) of different ARLON silicone foam densities at various thicknesses:

Density (lb/ft3)	Thickness	R-Value
5	0.25″	0.7
10	0.25″	1.0
5	0.5″	1.4
10	0.5″	2.0

As you can see, higher foam densities and greater thicknesses provide better insulation and thermal resistance.

Temperature Resistance

ARLON sponges can withstand operating temperatures from -100°F to 500°F. This makes them suitable for insulating applications with extreme high or low temperatures. The sponges will not burn or produce smoke and toxic fumes.

Compression Set Resistance

The silicone rubber retains its shape and thickness, even after long-term compression. This ensures consistent thermal resistance over time.

Applications

Here are some common applications for ARLON silicone foam insulation:

• Pipe insulation
• Ductwork insulation
• Appliance insulation
• Refrigeration insulation
• Automotive insulation
• Aerospace insulation

The sponges can be wrapped around pipes, lined in ducts, placed inside appliance housings, etc. They are also available as insulation tapes with adhesive backing for easy application.

FAQ

What are ARLON sponges made of?

They are constructed of silicone rubber. This gives them resistance to temperature extremes and excellent rebound properties.

How long do the sponges last?

With proper installation, they can insulate reliably for over 10 years. The material does not degrade or lose insulation capacity over time.

Can you cut the sheets to size?

Yes, the silicone foam can be easily cut to any size and shape using ordinary scissors or a sharp utility knife. The material is lightweight and flexible.

Are adhesives available?

Special silicone-based adhesives can be used to bond the sponges to surfaces if needed. The manufacturer also offers self-adhesive insulation tape.

Is the silicone sponge waterproof?

The closed-cell structure makes ARLON sponges water resistant. They can be used to insulate applications exposed to moisture or humidity.

Conclusion

ARLON silicone sponge sheets offer an efficient and long-lasting insulation solution. Their exceptional thermal resistance, temperature rating, and durability make them ideal for a wide range of insulation needs. Refer to the manufacturer’s data sheets for full technical specifications and installation recommendations. Properly installed, these sponges will provide reliable thermal protection for many years.
