Question: What is the range of compression set for liquid silicone?

 

Answer: The compression set range for liquid silicone is generally between 5% and 30%. Where 5% displays very little permanent deformation and 30% is relatively high permanent deformation. The grade of liquid silicone and the degree of completion of cross linking generally effects the final compression set. If compression set is a major issue for your project, it may be worth the time to post cure (A.K.A. Post Bake) your parts in order to complete cross linking of your parts. Your liquid silicone material supplier should be able to provide the compression set range for their liquid silicone.
