MSN-V40A is made of “polar” materials, which have excellent oil resistant property. Parts made of MSN-V40A exhibits good oil resistant property at a Shore Durometer OO hardness range. As many of polyurethane gel materials are made of polyether raw materials, which are more “non-polar” materials, the material tends to degrade quickly from contacts with oily substance. This combination of MSN-V40A's property can be utilized to make gaskets, seals, and other soft parts used in oily environments.
