DESMOPHEN 2000 Resistant O-Rings and Seals
DESMOPHEN 2000, also known as polyether polyol, is a type of polyurethane used primarily in the production of adhesives, sealants, and coatings. It is used in a wide range of industries, including automotive, aerospace, construction, and furniture manufacturing.
When exposed to DESMOPHEN 2000, rubber materials can experience swelling, softening, and discoloration. Swelling of the rubber material can occur due to the presence of hydroxyl groups in the DESMOPHEN 2000, which can cause the rubber material to absorb moisture and swell in size. Softening of the rubber material can occur due to the presence of hydroxyl groups, which can cause the rubber material to become softer and more pliable. Discoloration of the rubber material can occur due to the presence of hydroxyl groups, which can cause the rubber material to become discolored and fade in color.
Buna-N (NBR, Nitrile, Buna)
Buna-N o-rings also referred to as NBR o-rings and Nitrile o-rings are the most widely used o-ring material in the word because of low cost, good mechanical performance with resistance to water, most basic oils, lubricants and some fuels, many pneumatic, hydraulic systems, and the default choice for basic applications. Buna-N o-rings are not recommended for exposure to sunlight, UV light, ozone and general outdoor weathering or hash chemicals, acids, keytones and many others.
