Compression deformation of rubber pads
Thread Content
Emergency help! How much can a 1mm thick silicone rubber pad be compressed to, in millimeters? Its hardness is probably around 40. What about a 2mm thick one? We need to find a suitable sealing structure; please help!
According to the **testing standards for compressive deformation, temperatures below 50 degrees can be tested at a deformation rate of 40%. It shows that at least a 40% compression is definitely possible. It’s not clear what the maximum degree of compression is, but there’s one thing the original poster should keep in mind: the better the sealing performance of rubber, it isn’t the case that greater compression leads to better sealing. On the contrary, excessive compression will accelerate the loss of the rubber’s physical properties, resulting in reduced sealing performance and a shorter lifespan.
Compressive deformation is an indicator of the rebound property of the rubber compound, and it can also reflect the sealing property to some extent.
