- They are cost-effective, easy to install and highly flexible.
What is Nitrile Rubber Pipe Insulation Made Of?
The nitrile rubber pipe insulation is made of nitrile rubber or Buna R, a most commonly used elastomer. Nitrile rubber consists of unsaturated copolymers of acrylonitrile and butadiene monomers. The chemical and physical properties of nitrile rubber vary based on the polymer makeup.
What is the Difference Between NBR/PVC and EPDM Insulation?
Closed cell elastomeric insulation, also known as rubber, has been commercially available for almost 70 years. It’s commonly specified to insulate below-ambient (cold) mechanical systems such as HVAC, VRF/VRV, refrigeration, chilled water, medical gas, and cold water plumbing piping.
For the choice in building materials, analysis and comparisons are vital to make a correct product selection. Whether you are choosing cladding material for a skyscraper, or an insulation product for an HVAC or plumbing system, ensuring application and building codes requirements are met is crucial to an effective and compliant install. Variables like temperature, density, water permeability, or UV resistance can all impact a successful project selection.
In the mechanical insulation arena, there are options for almost every application and need. Unlike other insulation manufacturers, two of the most common elastomeric insulation materials for HVAC, chilled water, and refrigeration systems are produced based on nitrile butadiene rubber (NBR) and ethylene propylene diene monomer rubber (EPDM) technology. Both of these elastomeric foams are flexible, closed cell, and have a high resistance to moisture and water ingress. In fact, their water permeability is so low that they do not generally require additional water-vapor retarders. Also, with such high vapor resistance and surface emissivity, these elastomeric foams do an excellent job at preventing surface condensation formation.
Different Strengths and Different Applications
Even though NBR and EPDM seem to be similar, there are some key differences. NBR is a non-aromatic polymer compound, whereas EPDM is an aromatic polymer. Moreover, NBR is made using acrylonitrile and butadiene monomers, while EPDM is made using ethylene, propylene and a diene comonomer. Another significant difference in terms of application, is that NBR has a temperature range of -40°F to 180°F, while EPDM has a wider operating temperature range of -65°F to 250°F.
NBR stands alone as the most oil- and fuel-resistant elastomer. It is also known for maintaining its stability in low temperatures. On the other hand, EPDM is a heat, ozone, and UV-resistant rubber that has a great tensile strength, aging resistance, and abrasion resistance, as well as having a lower smoke density with average flame development especially at 1-1/2" and 2” thicknesses.
Both rubber cellular foam insulation products are proven alternatives to fiberglass on HVAC, chilled water, and refrigerant systems (piping, pumps, tanks, vessels, and spheres) due to its hydrophobic chemical composition, closed-cell structure, and built-in vapor retarders.
Frequently Asked Questions (FAQ)
1. What is the raw material composition of NBR PVC foam insulation?
It is made using high-performance butyronitrile rubber and polyvinyl chloride (NBR & PVC) as main raw materials, blended with high-quality auxiliary materials, and processed through a specialized foaming procedure.
2. What temperature range can this nitrile rubber insulation handle?
It operates efficiently in a wide temperature range from -50 °C to +110 °C (-40°F to 180°F), making it highly suitable for both hot and cold plumbing, refrigeration, and HVAC lines.
3. How does nitrile rubber insulation control condensation?
Its closed-cell structure and high resistance to water vapor prevent moisture ingress, which prevents condensation from forming on cold surfaces such as refrigeration copper piping and air-conditioning pipework.
4. What is the main difference between NBR/PVC and EPDM insulation?
NBR features superior resistance to oil and fuel and maintains stability at low temperatures. EPDM offers higher resistance to heat, ozone, and UV exposure with a wider operating range (-65°F to 250°F) and lower smoke density.
5. Is this foam insulation material difficult to install?
No, the material is lightweight, flexible, and easy to cut. Installing it on plumbing lines or ducting works is an easy, direct DIY task.
6. What fire safety ratings does this insulation achieve?
It meets strict building standards, achieving Class 0 & Class 1 fire ratings according to BS 476 Part 6 & 7 test methods.
