Plastics Industry Guide for Materials Testing
Materials Testing Systems are used in many different industries. A system used for plastics testing might differ greatly compared to a metals testing system. Universal Grip has compiled an index of curated and relevant industry specific knowledge.
Over 20,000 facilities make up the plastics industry in the United States. Plastics is the third largest manufacturing industry in the US and supports roughly 1 million jobs. Universal Grip estimates that there are between 5,000 to 10,000 installed universal testing machines that are used to test plastic. Benchtop tensile testers used in this industry are generally below 10kN (dual column) and in many cases can be single column (2.5kN).
Universal Testing Machines for Plastics Testing
There are four main components to a UTM:
3. Load Cell
There are two types of impacts tests, Izod and Charpy. Impact Testing for plastics is usually performed at lower forces around 1-25 joules.
Plastics Notched Charpy Testing - ASTM D6110
Plastics Notched Izod Testing - ASTM D256
Plastics Unnotched Impact Resistance - ASTM D4812
