contact usCompressive Strength. EPS is a closed cell, lightweight and resilient, foamed plastic composed of hydrogen and carbon atoms. The mechanical strength of EPS varies with its density. The most important mechanical property of EPS insulation and building products is its resistance to compressive stresses, which increase as the density becomes higher.

contact us· Two major forces act on a bridge at any given time: compression and tension. Compression, or compressive force, is a force that acts to compress or shorten the thing it is acting on. Tension, or tensile force, is a force that acts to expand or lengthen the thing it is acting on. As a simple example, think of a spring.
