  • Detail

Four synthetic leather industry standards will be implemented this year. Recently, the Ministry of industry and information technology approved and published four synthetic leather related standards in light industry standards, all of which will be implemented from October 1 this year

they are: (1) qb/t polyurethane for household use; 2. Safety technical conditions for leather formation in the chemical industry. This standard specifies the safety grade, requirements and test methods of polyurethane synthetic leather for household use. A variety of hydrogels with relatively good mechanical properties have been developed. This standard is applicable to polyurethane synthetic leather for household use made of base cloth, polyurethane resin and other main raw materials, through wet or dry polyurethane coating and post-processing

(2) general safety technical conditions for qb/t polyurethane microfiber synthetic leather. This standard specifies the safety grade, safety technical conditions and test methods of polyurethane microfiber synthetic leather. The standard is applicable to various types of polyurethane microfiber synthetic leather

(3) polyurethane synthetic leather for qb/t cap. This standard specifies the product classification, requirements, test methods, inspection rules, marking, packaging, transportation and storage of polyurethane synthetic leather for hats. This standard is applicable to polyurethane synthetic leather for caps made of various cloth bases through dry and wet polyurethane processing and finishing processes. Our engineers should consider the solution in this regard

(4) qb/t 208 must be rough ground 0-2010 high resilience flexible polyurethane foam. This standard specifies the classification, grade, requirements, test methods, inspection rules and marks, packaging, transportation and storage of high resilience flexible polyurethane foam. This standard is applicable to high resilience flexible polyurethane foam produced by block and cold curing mold with polyether polyol and isocarbamate as the main raw materials
