Why is Core Materials Gaining in Popularity Across Various End-User Industries?

Core materials, often called core compounds, provide the backbone of many modern building products, from roofs to superstructures. Some of these materials deliver superior fire retardant, thermal performance, dimensional stability, and sound insulation. The most popular closed-cell foams used in core materials include polyurethane (or PU), a product with multiple benefits. are the fundamental building blocks of modern aircraft, spacecraft, space vehicles, automobiles, robots, trucks, industrial equipment, and a host of other applications. They are generally made from high-quality lightweight alloys of aluminum, tin, steel, magnesium, or even titanium. They are used both in aerospace and commercial applications for their strength, stiffness, and lightweight properties.

One of the best-performing core materials available is medium to low density (30-60 pounds per cubic feet) closed-cell foam. These are actually some of the more affordable polymer composites that are used extensively in modern-day buildings: PVC (or polyvinyl chloride) and polyisocyanurate are two examples. Closed-cell foams, in which cells are manufactured in the same factory as the rest of a construction's product, have been used for decades in everything from roofing shingles and tires to marine engines and aircraft surfaces. This material's wide range of applications ensures that it can be adapted to almost any construction use.

Another well-known and versatile core material is thermoplastic polyurethane or PTU. Thermoplastic is a composite material that delivers high tensile strength and dimensional stability, as well as excellent resistance to moisture. Thermoplastic, used in roofing membranes as well as a wide range of other applications, can be used as framing layers, flooring materials, liner and sealant applications, and even as reinforcement in reinforced concrete.

Commercial uses are growing, but unlike military applications, commercial projects tend to focus on lightweight, flexible designs that can be used in a wide variety of end-use industries. This means that although core materials are primarily selected for use in commercial projects, they also play an important role in the aerospace and defense industry as well.

Why is core materials gaining popularity? Another reason that core materials are seeing such a sharp increase in sales over the past decade is that they have become an increasingly common alternative to high tensile steel in applications beyond aerospace and automotive. For example, there are currently an estimated two to three times as many cores as there are high tensile steel rings. The reason for this is that high tensile steel is generally not as durable or resilient as many other composites, especially when it comes to applications that require strength and durability.

Core materials such as PVC foam and balsa wood are making their way into every industry that exists. For example, nearly every type of airframe or missile system that is currently in use uses some type of material that is composed of at least one of these compounds. A prime example of this is the use of balsa wood in airbags and cushions for trucks. Even without the use of such lightweight plastic, such items can still provide exceptional support and much-needed shock absorption. Many manufacturers have even begun using these core materials for use in their own line of recreational vehicles to further reduce weight.
