Flexible elastomeric foam insulation

Types of flexible elastomeric foam insulation

Flexible elastomeric foam insulation is a thermal insulation material made from synthetic rubber, specifically designed for applications requiring flexibility, lightweight, and effective insulation. It is widely used in HVAC (Heating, Ventilation, and Air Conditioning) systems, plumbing, electrical, and automotive industries. There are different types of flexible elastomeric foam insulation, including:

• Uncross-linked and Non-vulcanized Foams:

  This type of foam is characterized by a lack of cross-linking between the polymer chains. As a result, it forms a non-vulcanized and uncross-linked flexible elastomeric foam. The absence of cross-linking leads to a more open-cell structure. As a result, it exhibits higher permeability to gases and liquids. Additionally, it has lower mechanical strength and thermal stability.

• Cross-linked and Vulcanized Foams:

  These flexible elastomeric foam insulations are created through a chemical process known as vulcanization. It involves cross-linking the polymer chains using heat and sulfur or other curing agents. The process results in a network structure that enhances durability, mechanical strength, and thermal stability. This foam insulation exhibits low thermal conductivity, high elasticity, and excellent resistance to aging and environmental factors. It is commonly used in applications requiring high-performance insulation, such as HVAC systems, refrigeration, and automotive components.

• Closed-cell Foams:

  This type of flexible elastomeric foam insulation is characterized by its structure. For instance, it has a high proportion of closed cells filled with gas or air. The closed-cell structure gives it superior thermal insulation properties. Also, it provides excellent resistance to moisture permeability and vapor transmission. Due to these characteristics, it is widely used in applications requiring high insulation efficiency and moisture control. For example, in refrigeration, pipeline insulation, and exterior wall applications.

• Open-cell Foams:

  These flexible elastomeric foam insulations have a structure that is predominantly composed of interconnected open cells. This results in lower density, higher breathability, and improved sound absorption properties. Open-cell foams are generally more flexible and lighter than closed-cell foams. They are primarily used in applications where moisture control and thermal insulation are more important than water resistance. For example, in interior wall insulation and soundproofing.
