Which type of rubber is suitable for frequent deformation?

2015-11-16View Original

Thread Content

I need to create a structure in which a large clip is used outside the rubber hose to control its flow – the clip opens when flow is allowed, and it closes around the hose to stop the flow. Since this action needs to be performed frequently, four or five times per minute, I would like to know what material would be suitable for this purpose. Thank you everyone.

Inside, dry powder cement is used, with a pressure of less than 0.6 Mpa. Now I want to use polyurethane; I’m not sure if that’s possible

The valve spool of pinch valves is usually made of fluororubber; yours should be similar

Thank you. I really didn’t know about clamp valves before, nor was I aware that fluororubber came in more specific varieties. Also, after reading your reply, I suddenly wondered whether the material used for airbags could be used as well. I originally planned to use polyurethane; I’m not sure which is more suitable compared to fluororubber

:Lol, no need to be polite. I just know what a clamp valve is; I’m not very familiar with the specifics of fluororubber materials, so I need someone who knows more to explain it to us so we can learn together*
