Plastic brittleness test
WebTheir brittle point is the highest temperature at which a plastic or elastomer fractures in a prescribed impact test procedure. Plastics that are brittle frequently have lower impact strength and higher stiffness properties. A major exception is reinforced plastics. WebJul 17, 2013 · We have two tests for brittleness, one is dry as molded, another is moisturized; as the part can be used dried or moisturized. The moisturized one is fine, …
