1、 Low thermal conductivity: rubber foam are high-quality thermal insulation and energy-saving materials, which can isolate cold, heat and dew. The thermal conductivity is low and stable, and can isolate any hot medium. When the average temperature is 0 ℃, the thermal conductivity of rubber foam insulation materials can be as low as 0.033w/mk, while its surface heat release coefficient is high. Therefore, under the same external conditions, using rubber foam insulation materials requires about half the thickness of other insulation materials, which can achieve the same thermal insulation effect, thus saving space above the floor ceiling and investment.

2、 Good fire resistance and flame retardancy: rubber foam thermal insulation materials contain a large amount of fire retardant and smoke reducing materials. The smoke concentration generated during combustion is extremely low, and it will not melt in case of fire, and will not drop the fireball on fire. It will extinguish automatically after leaving the fire source. According to GB- Grading Method for Burning Behavior of Building Materials, rubber foam insulation products are Class B1 fire-resistant materials to ensure safety and reliability.

3、 Moisture and moisture resistance: precision control micro foaming technology is adopted to greatly improve the cell closing rate and lower the thermal conductivity of the product; The bubbles are more uniform and dense, with strong resistance to water vapor penetration. The rubber foam are of closed bubble structure to prolong the service life. The water in the outside air is difficult to penetrate into the material, which has excellent resistance to water vapor penetration. It is unnecessary to add a vapor barrier on the surface of the cold insulation layer. Moisture resistance factor of rubber foam μ If the value is greater than (ISO), the built-in waterproof layer will be formed. Even if the product is scratched, the overall vapor insulation will not be affected. Rubber foam are both insulation layer and moisture barrier layer.

4、 Shock absorption and noise reduction: the sponge structure of rubber foam insulation materials makes them highly elastic, and has the functions of reducing vibration and absorbing noise, thus minimizing the vibration and resonance of chilled water and hot water pipes during use.

5、 Environmental protection and health: rubber foam insulation materials are very safe to use. First, rubber foam do not contain chlorine fluoride harmful to the atmosphere, which meets the requirements of ISO international environmental protection certification. Second, rubber foam materials do not contain fiber dust, which will neither stimulate the skin nor endanger health. At the same time, they can prevent mold growth, so they will not produce any pollutants harmful to human health during installation and application.

6、 Long service life: rubber foam have good weather resistance, anti-aging, anti cold, anti-inflammatory heat, anti drying, anti humidity, and also have anti ultraviolet, ozone resistance, 25 years of aging, deformation, maintenance free service life and other characteristics.

7、 Elegant and beautiful appearance: the rubber foam surface is flat, simple and elegant, soft and elastic. Even if it is installed on irregular components such as elbows, tees, valves, etc., it can remain complete and beautiful. The appearance does not need decoration, and even if it is not suspended ceiling, it can also maintain high-end.

8、 Convenient installation: because the rubber foam products are soft, the installation is simple and convenient. Pipe installation: it can be installed together after being sleeved, or it can be formed by cutting the pipe longitudinally and then bonding with glue. For complex components such as valves, tees, elbows, etc., the plates can be cut and bonded according to different shapes to ensure the tightness of the whole system, thus ensuring the thermal insulation of the whole system. Because of the smoothness and smoothness of the rubber on the surface of this material and its excellent performance, there is no need to add additional vapor barrier and protective layer, which reduces the trouble in construction and ensures the beautiful and smooth appearance.

3 Benefits of Elastomeric Insulation - Distribution International

Fiberglass, Foamglas, perlite, phenolic foam ... and elastomeric insulation? Elastomeric foam insulation was developed in the s as a synthetic alternative to natural insulation materials such as cork. The polymer-based insulating material has become popular over the years to protect the inner workings of buildings. Let’s dig into elastomeric insulation and its many uses across industries.

What Is Elastomeric Insulation?

Often referred to as rubber insulation, elastomeric insulation is closed-cell foam insulation that provides moisture resistance and long-term thermal performance. It is made from three components:

Synthetic rubber blend (e.g., nitrile butadiene rubber or ethylene-propylene-diene monomer)
Polyvinyl chloride (PVC)
Chemical foaming agent

What is unique about elastomeric insulation is that it has strong water vapor permeability, so you do not need a vapor barrier to prevent moisture transfer.

How Does Elastomeric Insulation Work?

Rubber insulation functions primarily as a thermal insulator. It manages heat gain and loss, as well as condensation control for mechanical systems without losing thermal efficiency.

This insulation is easy to implement because it does not require an outer protective jacket except in three unique situations:

During UV ray exposure
In cases where there is mechanical damage
In environments with extreme vapor drive

As a bonus, elastomeric insulation offers a non-fibrous alternative to internally lining ductwork, making it easier to meet project requirements.

What Are the Applications for Elastomeric Insulation?

Rubber insulation is available in a wide range of shapes and thicknesses — from sheets to rolls to tubes — making it ideal for various uses. For example, elastomeric insulation is commonly used in industrial and mechanical applications, including:

Refrigeration and chilled water piping
HVAC components
Interior and exterior duct systems
Chillers
Mechanical systems
Solar installations

Because it’s such a versatile and durable insulation type, elastomeric insulation works to safeguard your systems to operate safely and efficiently.

3 Benefits of Elastomeric Insulation

There is little worse than insulation that requires lots of in-field cutting and a complicated installation process. Luckily, rubber insulation is well known for how user-friendly it is because it bonds to various surfaces and is easy to install.

Elastomeric insulation stands the test of time, too. Its performance is not easily compromised because it’s less susceptible to:

Cracks
Breakage
Material loss

Rubber outperforms some of the most common rigid insulation, from cellular glass to polyiso to phenolic foam, and it boasts three major benefits: moisture resistance, air quality control and noise control.

1. Provides Moisture Resistance

Because of its closed-cell structure — wherein millions of tiny barriers resist liquid migration — elastomeric insulation is highly moisture-resistant. As a result, your systems are protected on two fronts: It minimizes mold risk because of its non-particulating, smooth surface, and it further protects piping and equipment from corrosion under insulation (CUI).

2. Preserves Indoor Air Quality

Going green is a big deal — and so is protecting your workers in an environment where they spend at least eight hours a day. Elastomeric foam safeguards indoor air quality because it:

Does not contain formaldehyde or fibers
Has very low volatile organic compounds (VOCs)

With this tag team, your operation releases far fewer chemical emissions, making the environment cleaner and safer.

3. Attenuates HVAC Noise

Far from simply acting as a thermal insulator, rubber insulation packs an extra punch as acoustic insulation for HVAC ducts—despite this being a highly specific application. If your owner project requirements (OPRs) require a certain degree of acoustic performance, closed-cell elastomeric insulation attenuates or reduces airborne and structure-borne sound from HVAC ductwork. Within your HVAC systems, elastomeric insulation effectively keeps fan noise and sheet metal vibration between 250-500 Hz.
