Invented over 50 years ago, elastomeric insulation continues to be one of the most effective insulations in many different applications. In this week’s article, we are going to explore how this synthetic material works and why it’s so effective as an insulation in HVAC, plumbing, and refrigeration applications.
Chemical Composition
Three main components are needed to manufacture elastomeric insulation: a synthetic rubber blend, polyvinyl chloride (PVC), and a chemical foaming agent. These ingredients are mixed together in massive batches, then formed into shape. Typically elastomeric insulation is shaped as a round tube or flat sheet. Once formed, the tubes or sheets are heated. The heat triggers the chemical foaming agent to transform from a solid to a gas. This process forms thousands of tiny, interconnected air pockets.
Simple Installation, Easy Upkeep
The composition of this insulation offers a few extremely beneficial characteristics. For one, elastomeric insulation can bond reliably to several different surfaces, making installation a relatively simple process. Furthermore, the structure of all those interconnected cells means that the insulation cannot be compromised by tears or punctures. As can be expected, this gives this product a long lifespan with relatively little maintenance.
A Secret Weapon Against Moisture
The most lauded benefit of elastomeric insulation is by far its high moisture resistance. Those air pockets create thousands, even millions, or tiny barriers that resist liquid. In this way, elastomeric insulation is one of the most effective products in high moisture applications. The reason that liquid transfer can be so dangerous to insulation is that it can create a prime environment for threats such as mold, while also compromising the effectiveness of an insulation. Wet insulation loses its thermal resistance and is no longer useful until it can dry. Elastomeric insulation simply doesn’t take in liquid, so the result is steady, long-term thermal performance.
When it comes to applications where condensation is a concern, like heating, ventilation, and air conditioning, elastomeric insulation is a viable solution. If you’re interested in this type of installation and want to know if it’s right for your facility, contact us today for a consultation.
