Impact resistance refers to the durability of a material when it is subjected to instantaneous large forces.
While hard materials exhibit great durability when loaded slowly, most materials crack easily when subjected to instantaneous force such as hitting with a hammer. In other words, they are hard and brittle materials. This can be said to have low impact resistance.
Therefore, to improve impact resistance, it is necessary to design a material that strikes a balance between hardness and brittleness.
The main methods to measure impact resistance are the Izod impact test and Charpy impact test.
We handle a variety of unique urethane resin products with excellent impact resistance that optimize this balance between hardness and brittleness.
