Neoprene rubber washer
Neoprene rubber washer is the right choice if you need rubber washer that will be in contact with acids, solvents, oils and similar types of very aggressive substances. It should be borne in mind that it is resistant to mild acids, while very strong acids can damage it. Neoprene, which is also called polychloroprene because it is a synthetic type of rubber that has extremely good chemical stability and that is why it is ideal for contact with the above-mentioned substances.
Neoprene rubber washer retains flexibility even when temperatures change, which is very important. Although it should not be exposed to such high and low temperatures as silicone, for example, because neoprene should not be exposed to temperatures above 150 degrees Celsius, retaining flexibility is crucial, even at very cold temperatures. You can use neoprene rubber washer to create a tight fitting seal to prevent leakage of various substances including water. That’s why you can find neoprene rubber washer on different hoses and the like, because it has the function of creating a tight fitting seal and preventing any liquid from leaking out where it shouldn’t. Another important thing is that neoprene rubber washer also serves as corrosion protection.
It is also useful to distribute the weight properly and thus the neoprene rubber washer prevents various types of damage. In order to be able to create a tight fitting seal, it is necessary that the neoprene rubber washer be of the ideal size. It must not be a little smaller or a little bigger than necessary, otherwise you will not achieve what you want. Finding the ideal size will certainly not be a problem, because the choice is a big plus the ability to order a custom washer. Hardness is Shore A 40–95, so neoprene is harder than some other rubber materials.
