URETHANE INDUSTRY GLOSSARY - Y |
Yield Point See elastic
limit. This is the point in compression or tension loading of a sample beyond
which permanent damage to the structure of the sample results. Before this point
complete elastic recovery will occur. Commonly rigid foam
is defined as that foam having a yield
point of less than 10% (compression or elongation).
Yield Strength The force required to bring a specified sample of foam
to the yield point. The force is
usually stated in pounds per square inch.
