Abstract:
Quality control and materials development of cellular polyurethane foam used in light-duty automotive air filter seals rely on measurement of mechanical and physical properties such as tensile strength, elongation, compression set, specific gravity, and durometer hardness. These properties are typically measured on specimens cut from slabs formed in preheated closed molds. However, these slabs are nonuniform in specific gravity, and property measurements vary with location within a slab. The effect of sampling location on mechanical and physical properties is discussed.
