[18] The size of Coronavirus is identified to be on average 0.125 microns.[19]. [citation needed]. 10 Steps Everyone Can Understand. This feature is the reason why sponge neoprene is ideal for seals and gaskets that need a really tight seal. The durometer (or measure of rubber hardness) is measured in shore “A” for solid neoprene and Shore “OO” for cellular neoprene. They can withstand similar temperatures--a high of 149 degrees C for EPDM and 121 degrees Cor Neoprene, and a low of -60 and -40 respectively. They sound very similar but they are two different fabrics with different advantages and disadvantages. Used for electrical insulation or automotive belts, they have become valuable parts in common products within our market. Neoprene (also polychloroprene) is a family of synthetic rubbers that are produced by polymerization of chloroprene. This culmination of higher durometer and tensile strength contribute to its solid form ability to endure conditions that experience constant wear. [8] To prevent shoddy manufacturers from harming the product's reputation, the trademark DuPrene was restricted to apply only to the material sold by DuPont. As for temperature, it is the compound blend that would determine the range. Neoprene is a form of rubber often used for wetsuits and other water products.
