Most of the time, though, LDAP is used to search for information in the directory. The LDAP search operation allows some portion of the directory to be searched for entries that match some criteria specified by a search filter.
It has good low temperature flexibility and is superior to most elastomers in compression set, cold flow and abrasion resistance. However, it does not possess good resistance to ozone, sunlight or weather. Buna-N has a temperature range of -40 to+135 C (-40 to 275 F).
Nitrile rubber. Nitrile rubber, also known as Buna-N, Perbunan, or NBR, is a synthetic rubber copolymer of acrylonitrile and butadiene.Trade names include Nipol, Krynac and Europrene. Nitrile butadiene rubber is a family of unsaturated copolymers of 2-propenenitrile and various butadiene monomers.t is used in the nuclear industry to make protective gloves. NBRâs ability to withstand a range of temperatures from -40 Â°C to +108 Â°C makes it an ideal material for aeronautical applications. Nitrile butadiene is also used to create moulded goods, footwear, adhesives, sealants, sponges, expanded foams, and floor mats.
