C-4310 is a white CR rubber sponge. Its hardness is 23±5°, which is almost the same as general-purpose materials, and it is processed into items such as gaskets.
C-4310 is a foam product made of neoprene rubber, and while many rubber sponges are black, this one is white. Due to its independent bubbles, it does not allow liquids or gases to pass through. It also excels in oil resistance and weather resistance. Furthermore, it meets the flame retardant standard equivalent to "UL94 HF-1."
