The sponge rubber is small, DIA. 2-7 mm, has a standard hardness or Hardness that is higher than a large SIZE sponge rubber, which is a solid sponge rubber DIA. . 2-7 mm has a hardness or Hardness 70+/5 Shore OO. The large sponge rubber DIA. 8-60 mm has a hardness or Hardness 60 +/- 5 Shore OO.
The main reasons that make the sponge rubber SIZE small (DIA. 2-7 mm) have hardness or Hardness that is higher than SIZE large round sponge rubber (DIA. 8-60 mm) is from the “collapse problem of Solid sponge rubber" Sponge rubber, small SIZE, low hardness, causing a lot of collapse than large SIZE sponge rubber, resulting in less strength. Therefore, it is a problem in the matter of implementation in the end.
For this reason, sponge rubber, small SIZE (DIA. 2-7 mm), most people use it at hardness or Hardness 70+/-5 Shore OO
But if the customer wants to use a specific area and has a special low hardness It can specify the hardness that the factory produces as a special case.
