Extruded Compounds
When it comes to industrial applications, selecting the right material for resistance against various chemicals is important. Different compounds demonstrate a variety of levels of resistance to industrial chemicals, impacting their suitability for specific applications. Within the guide, it provides a detailed analysis of how common extruded compounds perform under exposure to various chemicals.
Chemical Resistance of Extruded Components
Industrial compounds like cross-linked polyethylene (XPLE), PVC, EPR (Ethylene Propylene Rubber), Neoprene, Polyethylene, and EPDM (Ethylene Propylene Diene Monomer) are used in diverse applications ranging from cables to seals and gaskets. The resistance to damage when exposed to different chemicals can vary significantly, and understanding these differences is key to choosing the most suitable material.
Resistance to Industrial Chemicals
The resistance of these materials to various chemicals has been evaluated using the ASTM D-543 testing method, which involves exposing the materials to chemicals at an elevated temperature of 80°C for 7 days. This testing approach provides reliable insights to the performance of each compound under challenging conditions.
