National identification number "Teudat Zehut"), bearing an Identity Number, is issued to all residents over 16 years old who have legal temporary or permanent residence status, including non-citizens. Japan's national identification number system, known within the country as "My Number" (Japanese: マイナンバー), went into effect from 2016. The number consists of 12 digits, and one is assigned to each resident of Japan, including non-Japanese long-term residents with valid residency permits. In Kazakhstan there is a 12-digit Individual Identification Number for natural persons (abbreviated in , "ZhSN"; in , "IIN", with first six digits representing person's date of birth in the YYMMDD format) and
Kraton (polymer) consisting of polystyrene blocks and rubber blocks. The rubber blocks consist of polybutadiene, polyisoprene or their hydrogenated equivalents. The tri-block with polystyrene blocks at both extremities linked together by a rubber block is the most important polymer structure observed in SBC. If the rubber block consist of polybutadiene, the corresponding triblock structure is: poly(styrene-block-butadiene-block-styrene) usually abbreviated as SBS. Kraton D (SBS and SIS) and their selectively hydrogenated versions Kraton G (SEBS and SEPS) are the major Kraton polymer structures. The microstructure of SBS consists of domains of polystyrene arranged regularly in a matrix of polybutadiene, as shown in the TEM
